From Perth to Melbourne, I was able to hitch 2 rides. The first was a quick hour ride to Dunbury. I got picked up by this guy, let's call him Andy. As I put my bags in the bed of his ute, he comes around back with a case of beer. We end up driving an hour or so drinking along the way. This is something I would not have ever imagined doing. What a great experience.
The next and most interesting ride was from Dunbury to Melbourne. I met this guy on gumtree, Craigslist for Australia, and we ended up driving the remainder of the trip to Melbourne. But this was no uneventful road trip. On the way, we got stuck in Esperance for 2.5 days, hit two kangaroos before crossing the border into south Australia, got pulled over for speeding and got hit by a car that almost flipped us. This all happens in a span of 1.5 days and we still manage to make it to Melbourne in the same car. Try saying that in one breath.
All in all, I would have to say that hitchhiking across a country the same size as the US is quite a feat. It has really opened my eyes to a different world and level of trust. Five years ago, I most likely would not have even thought about hitchhiking or picking up hikers. Now, after experiencing the wait with your thumb out and trusting my personal effects with other people, I am able to read a person and their intentions a bit more effectively. Plus, i can say i played the longest game of kangaroo golf in all Australia. This is a win.
