There's sweet FA in WA
And that's what's so great about it!
Western Australia or WA is Australia's largest state, and that pretty much puts it at about the same size of half of mainland Europe. Over the last week Emma and I have been exploring it, or a very small part of it, namely a 1500km long stretch of coastline that unravels north of Perth, in an attempt to get in touch with the 'real' Australia. We realised that the most economical way to travel through this part of the country would be to hire a car, camp in the bush and on the beaches along the way, and cook our own food.
Our route took us along parts of the coast but also over vast tracts of inland wilderness; the famous Australian outback. It is a unique experience to drive through such an environment. Seemingly endless sections of straight road are surrounded by a consistent mess of bush, tracks that venture off the road look promising but soon peter out into impassable quagmires of sand, and the occasional fuel-selling roadhouse provides the only major evidence of human influence in an environment that is simultaneously beautiful and inviting but deceptive and deadly. I suddenly attained a great respect for the explorers who first came to this continent and had the nerve to attempt to stray into the unknown red centre of the country in order to try to cross it from the south to the north. The first explorers to survive the crossing died on the return journey.
On top of experiencing the outback we found numerous deserted beaches and visited several national parks and marine reserves. Emma's writing more about one of the highlights of the journey, Ningaloo reef, in her blog, which you can reach via my sidebar.
I'm going to write a little about the intriguing stromatolites of Hamelin Pool, Shark Bay which we found on our second day, 800km north of Perth. Bill Bryson mentions these interesting biological phenomena in his hilarious book Down Under, and after having read the book in Peru I was keen to visit them if ever I had the opportunity to.
Stromatolites are deceptive. They look like rocks, and they more or less are rocks, but with an extra twist. They're alive. These intriguing creatures once dominated life on earth for 2 billion years. They consist of a primitive form of bacteria known as cyanobacteria, which collectively join together and trap sediment. Over time, this materializes into a tangible structure which, on a long enough timescale, grows and spreads. When geologists first visited Shark Bay they were amazed to find evidence of stromatolites living today, as it was previously believed that there were no modern day examples of an organism which once dominated the earth and eventually evolved in to all other living things. The stromatolites of Shark Bay exist because the hypersaline waters of Hamelin Pool prohibit any of their natural predators, which include sea snails, from grazing on them and destroying them. A different species of stromatolite exists somewhere in the Bahamas, and there exist freshwater versions in Mexico, but otherwise the stromatolites of Shark Bay are unique. It was amazing to gaze in to the water below the boardwalk and see evidence of one of the first forms of life that miraculously spawned out of the primordial soup.
Here are some more pictures from our trip.
We're now back in Perth and are looking forward to spending a couple of days south of Perth (in one of the wine regions, not coincidentally) with my cousin Emma. Then we'll be off to Darwin to spend a few days in Kakadu National Park (think Crocodile Dundee) before changing countries again. Indonesia beckons!
