July 2014 - Katherine to Litchfield National Park

As we leave Lake Argyle and start heading east again, we bid a fond farewell to Western Australia as we crossed the border into Northern Territory.
With the Kimberly region behind us we moved into the Victoria River region and soon found more breathtaking views.
Timber Creek is the first little settlement in NT coming from the west, it is right on the Victoria River and provided us an ideal overnight stop before crossing the river at Victoria River Roadhouse and then on to Katherine.
The star attraction at Katherine is undoubtedly the famous Katherine Gorge which was renamed “Nitmiluk”(meaning “cicada place”) in 1989 when traditional owners, the Jawoyn Aboriginal people gained title to this land.  The easiest way to see the gorge is to take a tour with Nitmiluk Tours which is a 100% Indigenous owned organization and the sole tour operator within this national park.
Nitmiluk Gorge is a maze of waterways sculptured from the sandstone over countless years by the Katherine River, and consists of 13 separate gorges as it winds its way along 12 kilometres of sheer rock cliffs, most of which are more than 70 metres high.
During the current dry season, the river is very shallow in places and there is no water passage between the separate gorges, so the tour operators have boats stationed up river from each blockage.  The tour took us through the first gorge and then we had to disembark the first boat and walk about 600 metres over the rocks along the river bank to the water of the second gorge.  We passed these rock paintings along the way.
The next boat then took us up river into the second gorge which was more spectacular than the first.  The river is a haven for fresh water crocodiles which are currently preparing to lay their eggs along the sandy banks of the river.
We were lucky enough to see 4 or 5 as we traveled along the river. Salt water crocodiles only enter this part of the river during the wet season and the park ranges have a busy time trapping them to keep this section of the river safe for swimming and other water activities.  The lesser known attraction of Nitmiluk is Leliyn or Edith Falls as previously named.
These falls are about 52 kilometres north east of Katherine on the Edith River and the pandanus fringed plunge pool offers a great place to cool off with a swim in beautiful clear cool water.  The pool was about 5 feet deep while we were there and you could clearly see the bottom of the pool while standing in the water, another of those beautiful places that we came across unexpectedly.
The opposite of the cool water of Leliyn is the warm waters of the Katherine Hot Springs where the crystal clear waters are at an idyllic temperature of 32 degrees. The spring which winds its way through a number of tree lined pools and out into the Katherine River makes a great place for a swim.
The Northern Territory pastoral industry generates more than $300 million directly and $880 million in directly into the Northern Territory economy. This magnificent one and a half times size bronze statue acknowledges the industry forebears, salutes those who currently work the land and encourages others to cherish the challenges of tomorrow.  With the school holidays on for a month in the NT, we found that all caravan sites in Darwin were booked out until the last week of July, so we had a couple of weeks to fill in between Katherine and Darwin.  We headed west again for about 100 kilometres from the Stuart Highway into a little settlement on the Daly River.  All reports were that the fishing was good and the caravan parks had room available.
We stayed at the Banyan Farm Tourist Park which is right on the river and has plenty of shade and surrounded by pandanus ferns.  We were warned to keep back from the river as there was a 5 metre salt water crocodile captured and removed from their boat ramp the week before.  We were also told that the river was full of bull sharks which surprised us as the park is about 90 kilometres upstream from the mouth of the river.
Some of the other fisherman in the park with boats told of catching fish and only landing the head as a crock or shark took the rest as they were reeling it in.  Needless to say we didn't put the Zodiac in the water for fear that the crocks would use it for a teething ring.  I only caught a lousy cat fish, but it was a bit of fun anyway.
Heading back towards Darwin again we stopped at the lovely little oasis of Adelaide River, which is home to "Charlie" the water buffalo made famous by the Crocodile Dundee Film.
More importantly, It is also steeped in WW2 history. During the Second World War, the Northern Territory contained the largest operational base in the South West Pacific.  Darwin, the capital, became a naval base and suffered its first air attack on 19 February 1942.
Within a month of the first air raid, Darwin became the heart of this important operational base.  From its airfields around Adelaide and Batchelor, the Royal Australian Air Force raided Timor, Dutch New Guinea, Borneo and islands in the Arafura Sea.  Both Adelaide River and Alice Springs were the headquarters of large base establishments and the main north–south road from Darwin to the rail head at Alice Springs was built during the war.
During the Second World War, Adelaide River was the headquarters of a large base and the Adelaide River War Cemetery was created especially for the burial of servicemen and women who died in this part of Australia.  After the war, the Army Graves Service moved graves from civil cemeteries, isolated sites and temporary military burial grounds, into the Adelaide River War Cemetery.  There are 434 burials, comprising 14 airmen of the Royal Air Force, 12 unidentified men of the British Merchant Navy, one soldier of the Canadian Army, 18 sailors, 181 soldiers, 201 airmen belonging to the Australian forces, and seven men of the Australian Merchant Navy.  This war cemetery is the third largest in Australia, it is absolutely impeccably maintained and it is a moving experience to walk through the grounds and read the tomb stones, with so many of the dead being men and women of a very young age.
Berry Springs just south of Darwin is home to the Territory Wildlife Park, where the NT government have turned some virgin bush land into a wonderful natural setting to house birds, fish and animals in their natural surroundings.  We saw the Birds of Prey show at the Flight Deck which showcased raptors, (birds that catch their food with their feet).
The owls and osprey were great but the highlight of the show was the red kite which used a stone he picked up in his mouth to break open an emu egg.  These are the only birds known to use tools to gather food.
Next was the aquarium where they have a large salt water crocodile as well as a big variety of fish, including the illusive barramundi. The Monsoon Forest Walk starts with a monsoon that includes thunder and lightning and pouring rain that really makes you think it is the real thing. The walk then continues for about a kilometre which takes you through various bird aviaries and into one of the largest domed walk through aviaries in the southern hemisphere.
We were very pleased to see that one of the aviaries had a pair of Gouldian Finch which had recently hatched out 5 young.  In 1992, these birds were classified as "Endangered in the wild” because the viable population size was estimated to be less than 2,500 mature individuals.  This finch was found all across the top of Australia some years ago and we have been trying to find one since we first read about its plight when we were in Wyndham. Fortunately, these finches breed well in captivity, so with a good breed and release program, places like this wildlife park will ensure that this beautiful little bird doesn't become extinct. Once again a good photo was hard to get so this one is from the internet.  Litchfield National Park has played second fiddle to Kakadu for many years, but following many recommendations from other travelers, we decided that we were too close not to take a look, and we weren't disappointed.
Batchelor township, which lies at the gateway to the park, began to flourish in 1949 with the discovery of uranium at Rum Jungle. This was Australia’s first uranium mine and became one of the greatest economic influences on the subsequent development of the Top End.
First stop within the park is the Magnetic Termite Mounds.  There are 2 types of termites here in the Top End and both build very different types of mounds. The magnetic termites, which are not found anywhere else in the world, build their mound exactly north and south in the black soil of the flood planes with their flat sides then facing exactly east and west.  This is a marvelous feat given that these termites are completely blind so they can’t use the sun to guide them.  Scientists proved their theory that the termites have a built in compass by placing strong magnets beside the mounds away from the north / south direction, and the termites dutifully followed and built repairs to their mound in the alignment of these magnets.
The other termite here is the Cathedral termite which build their mounds on well drained soil. These mounds can be up to 5 metres tall and take up to 50 years to build, which is very impressive achievement for a 5 mm long termite.
Continuing further into the park we came across Florence Falls which were easily viewed from a well constructed platform on the opposite side of the creek. There is a walk along a 1.2 kilometre track or down 135 steps to get to the pool at the base of the falls.
We gave that a miss in the 32 degree heat and went on to our picnic lunch spot at Bluey Rockhole where we sat on a creek crossing and dangled our feet in the cool water surrounded by pandanus and other palms.
Our last stop for the day was another 30 kilometres further into the park at Wangi Falls which is another one of those unforgettable “wow” moments on our trip.  The car park at Wangi Falls is only about 250 metre walk from the pool and viewing platform at the base of the falls.
Wangi Falls is fed from a spring in the dry season and its water spills over the sandstone cliffs of the Tabletop Plateau down into the plunge pool about 150 metres below.  The pool has cool, crystal clear water and black bream or sooty grunter can be seen swimming around the edges looking for food. This is a safe swimming pool during the dry season as only a few small fresh water crocodiles inhabit this area, but the pool is closed to swimming during the wet season as the extra water flow makes dangerous currents and saltwater crocodiles manage to find their way in here.
The bush all around the Top End is full of Kapock trees which are very obvious when they are in flower as they loose their leaves before a brilliant yellow flower appears.  The aborigines use these as their calendar tree as it tells them that the crocodiles are about to lay their eggs when the tree is in flower.
Other bushes that really stand out in the Top End is the turkey bush with it’s brilliant mass of purple flowers.  Aboriginal people would squeeze the juice from the flowers and use it as a pain killer.  If the colours of the Kimberly were yellows and red, the colours of the top end are certainly orange with red and brown.
The Banksia trees in full flower throughout Litchfield National Park really show off the orange colours of the top end.  From Litchfield it's soon time to move onto the big smoke of Darwin, but for now it is just great to sit back and enjoy what the territory has to offer.

June 2014 – Kununurra to Lake Argyle

With the outside air temperature still at 32 degrees it is hard to believe that we are already 5 weeks into winter, however the trees seem to know and the leaves have turned to autumn colours and the wattle has flowered.  This gives a real yellow tinge to the east Kimberly which really stands out against the deep red background of the rocks and mountains.
The road between Bungle Bungle and Kununurra passes through the Carr Boyd Ranges which is an ever changing landscape, and the turning of the grass adds to the yellow tinge creating the unique colours of the Kimberly.   
 As Kununurra was only gazetted in 1961, it is one of the youngest towns in Western Australia which was developed through the construction of the Ord Irrigation Scheme.
The Diversion Dam which was the first stage in the construction of the scheme comprises of 20 radial gates that are raised or lowered to regulate the water level in Lake Kununurra, primarily to maintain water flow to the irrigation area and also to manage wet season flood levels.  This dam wall which was completed in 1963 also forms part of the Victoria Highway at the west side of the town.  Unfortunately the Ord River Irrigation Scheme has had a number of spectacular failures, pushed by successive governments. First was the cotton crop from 1963 to 1974. The high number of pests meant the cotton had to be sprayed every two to four days, a massive use of millions of litres of pesticides, which made it nonviable so it was eventually abandoned.  Next to come were peanuts and rice. The rice crop attracted 8000 to 10,000 magpie geese an hour which meant the airport became unmanageable and eventually rice was also abandoned.  The growth of vegetables has been successful and many are still grown today, subject to massive irrigation from the Ord River.
On our approach into the town we noticed what appeared to be tree plantations with 3 or 4 different species of trees all planted in consecutive rows. We found out during our look around town that these are Indian Sandalwood plantations.  The reason for the different species of trees all in the same plantation is that Sandalwood has a poorly developed root system and is classified as a hemi-parasite, due to its inability to fix nitrogen in the soil.  It therefore needs other trees and legumes to grow around it for it to grow and survive. Sandalwood has been an integral part of Asian culture and religion for thousands of years, and remains a key ingredient in leading fragrances and cosmetics.  Sandalwood features in incense, perfume, carvings, medicines, fashion, furnishings and religious ceremonies around the globe.  The Indian species of Sandalwood commands the highest price at auction due to its superior oil yields and long-term market acceptance.  The price of wild Indian Sandalwood sold at auctions in Indian has continued to increase over the last 20 years with the price for Indian Sandalwood logs averaging over A$100,000 per tonne.  The unique climate of Australia’s tropical north provides an ideal location for the growth of Indian Sandalwood.  It was first planted in Kununurra in 1999 and a further 7,500 hectares of commercial Indian Sandalwood have been planted since.  Sandalwood plantations in Western Australia are assisting to lower the watertable and reduce salinity problems across the Ord River Irrigation Area (ORIA).  The bio-diverse nature of Sandalwood plantations also makes them an ideal nesting place for native birds.  As with any large scale farming operation, there are always pros and cons.  Of course the Sandalwood growers are very positive and predicting excellent returns over 20 years, but the skeptics say that this area should be kept as a food bowl producing fruit and vegetables.
Another new crop being grown around the area is a little known ancient seed that has emerged as the most lucrative crop option for Stage 2 of the State and Federal Government's $415 million investment in the Ord River Irrigation Development project. The chia plant, first used by the Aztecs, produces a tiny seed that is the richest plant source combining Omega 3, dietary fibre, protein and antioxidants, making it the most nutritional grain available and therefore contributing to a healthy global community.  Growing chia is very latitude specific, it has to be grown in the range 15-20 degrees north or south of the Equator to optimise the Omega 3 ratio in the oil.  Chia needs to be grown during the dry season as the seed is hydrophilic meaning that it is covered by a microscopic fibre that turns to gel when it comes in contact with water.  The gelling is one of the key nutritional and functional benefits of chia, but if chia gets rain on it, it will ruin the crop.  It is interesting to see how these new crops develop and the chia harvest is said to be worth $20 million by 2015.  As we travel around, we are always amazed at the amount of different things that we find that are said to be unique to that particular area.
Zebra Stone is another one of these things which is only found near Kununurra in the Kimberley Region of Western Australia.  This is a rare and beautiful stone said to be formed long before animal life moved about earth.  The totally unique Zebra Stone has been estimated to be 600 million years old and the only deposits in the world have been discovered right here, just east of Kununurra.  It consists of a fine grained siliceous argillite with rhythmic patterns of red bands or spots contrasting sharply with a lighter background.  It is not known how the regular patterns were formed but the red stripes are coloured ferric (iron) oxide.  Geologists have investigated Zebra Stone without producing any valid explanation of its origin.  The rock's natural beauty typifies the colours and spirit of Australia and some have said that the stone has a special quality for bringing luck.  There are 3 or 4 galleries around town that work with this stone and make some beautiful sculptures.
We were lucky enough to pick up this beautiful little partly finished crocodile straight from the workshop at a fraction of the finished price.  All I need to do is give him a good clean up with wet and dry sandpaper and then a couple of coats of clear varnish to make the colours stand out.  
We weren't going to visit Wyndham but after finding some advertising on Parry Creek Farm we decided that it would be worth back tracking a bit and we weren't disappointed.
We stayed at the Parry Creek Farm right near the Marlgu Billabong in Parry Creek Reserve which is a natural habitat for hundreds of birds and the odd fresh water crocodile or two.  They have built a walkway out beside the lagoon with a bird watching hide at the end.  While we were standing there a crocodile swam stealthly under the water right below to where we were standing in the bird hide.
We could see bubbles coming up but couldn’t see him.  He surfaced briefly right in front of us after about 10 minutes and we could plainly see that he was about 2.5 metres long. He must have decided that it would be too hard to get to us so off he went.  Just goes to show how easily you could get attacked if you were standing by the waters edge.
We spotted a rare Rainbow Bee Eater.What a beautiful bird but my photos turned out poorly so I grabbed one off the internet.  Wyndham is the Kimberley's oldest town, Western Australia's northernmost town, and it's also Australia's hottest town. Marble Bar might claim the highest peak temperatures, but Wyndham has the highest year round average temperature.
The first thing you see when entering the town is the giant crocodile which was built by a group of students back in 1980.  She is made up of 55 kilometres of steel rod, 50 kilograms of welding rods, 10 rolls of bird mesh and 5 cubic metres of concrete.  Wyndham has a lot of history going back to the 1880’s which was first sparked by the gold rush, followed by supporting the pastoral industry with a thriving meat industry as well as imports and exports from the wharf.  The Port of Wyndham was an integral link with the outside world and supported the whole of the East Kimberly region.  Camel, bullock and donkey teams were vital for the transportation of goods from the port to outlying stations as far afield as Halls Creek.(375 kilometres by todays roads).
Now days the biggest thing that happens in town is the export of iron ore from the Ridges mine which is 165 kilometres south west of Wyndham.  38 road trains travel down to the mine each day and bring 150,000 tonnes of Iron ore fines in 110 tonne loads back to the port each month.  As the port is on the river it is not deep enough for ships to come in, so the iron ore is loaded onto barges and towed out to the waiting ships anchored in the Cambridge Gulf.  A 65,000 tonne ship is loaded every 2 weeks with a tug towing 2 or 3 barges transferring iron ore to the ship.
The wharf and surrounding area can be seen from the Five Rivers lookout on top of the Bastion Range which is 350 metres above sea level. The Forest, Pentecost, Durack, King and Ord rivers all enter the Cambridge Gulf at Wyndham.
A proud monument to the indigenous heritage is on display at Warriu Park where the Dreamtime Statues can be seen depicting early aboriginal life at Wyndham. The Statues were built as part of a Bi-Centenary project and originally intended for Kings Park in Perth as an Indigenous People contribution towards Reconciliation and the development of a new Australian society.
One of WA’s best kept secrets is the caravan park at Lake Argyle.This place has one of the best infinity swimming pools with one of the best backdrops you could ever find anywhere.The caravan park is tree to tree grass as you would imagine with all that water available.
It is a real resort style caravan park with a bar and restaurant right on the site that serve beautiful meals at very reasonable prices in a beautiful outdoor setting. Lake Argyle is the water supply for the Ord River scheme at Kununurra.  It is Australia’s largest expanse of freshwater covering an area of more than 900 square kilometres at full supply level and up to 2000 square kilometres when in flood.  At full supply level it holds 21 times more water than Sydney Harbour.
We took a cruise on an unusual boat called the Kimberly Durack which is named after the grazier whose family moved into this area from central Queensland in the early 1800’s.  Kimberly had a vision for the Ord River scheme at Kununurra as well as the lake to supply the water.  It was their property that was flooded when the dam wall was completed to make the lake.  Ironically, Kimberly died in 1968 just as the dam was starting to be built.
The dam wall which is only 334 metres long has been built across the Ord River between 2 solid rock walls. The wall is 67.5 metres above the original river level and it was constructed using 1,522,306 cubic metres of rock fill and 243,111 cubic metres of impervious clay as a core to give the wall some flexibility.  The rock for the wall was blown out of a mountain only about 2 kilometres away from the wall site.  The first blast shattered just under 1 million tonnes of rock and the second blast the following year blew out just over 1 million tonnes of rock.  This is still the biggest single blast undertaken in Australia to this day. The blast registered 5.4 on the Richter scale all the way across the country in Sydney.  It is believed that if this wall was to fail, it would only take 15 minutes to flood Kununurra which is 35 kilometres away by river.  It would also then take 4 years for the lake to completely empty.  When the dam wall was completed in 1973, it was expected that it would take 8 wet seasons to fill the lake but it was filled in less than 3 years, which left a lot of the Durack station buildings go under water.
Fortunately they were able to pull down the original homestead and relocate it to higher ground at a later stage.  The house is now a wonderful museum to the Durack family and the early years in the Kimberly.
The cruise took us about 7 kilometres down the lake and around a lot of the many islands that the water created and out into the big section of the lake. This gave us a better idea of the size of the lake as 35 kilometres off to the east was the edge of the lake near the Northern Territory border and 55 kilometres to the south is the Argyle Diamond Mine along the southern edge of the lake.
One of the highlights of the tour was a swim in the lake at sunset with a wine , soft drink or ice cold beer.  The boat anchored in 32 metres of water and in we went for a cooling swim.  What a great place to swim and watch the sun go down for the evening.
Now days there is a 30 megawatt hydro power station at the bottom of the wall which supplies power to Kununurra, Wyndham and Argyle Diamond Mine.  This little power station replaces diesel power stations which used to burn 60 million litres of diesel annually.
We moved from the West Kimberly to the east and kept thinking that the Pilbra region further south was better, but after continuing on our way east. we have found just as many awe inspiring sites along the way.
I cant resist taking a photo of a boab tree at sunset
