I have just returned from 4 days in the Western Australian bush. we took the Bibbulmun Trail (which goes from Albany to Perth) from Dwellingup to North Banister.
As trails go this is a very luxurious one. Hiking an average of 15km with huts at each stop, many more experienced hikers would simply double hut and cover twice the distance in one day. Most huts slept up to twelve people and were almost never populated by just one group. The fact that we didn't need to carry tents with us made all the difference. The trail is also nice because, for those hiking long distances, there is a restock town about every 4-7 days.
The most awsome part about being in the bush was the change of scenery. I felt as though I was in Jarassic Park. For someone who is not accustomed to the Aussie wilderness it was quite a different environment. We saw lots of little gray kangaroos and one big red one and a few lizards. The trail was busy and we stayed with at least on other group each night. I'd like to come back and do the whole thing end to end some day.
