I've only just seen this and felt I should reply to granjura. Some years ago, having been made redundant and the children not needing me around all the time, I treated myself to a 3.5 month trip, including Oz. I booked much of it through a travel agent in London who specialised in such things. I flew out via Thailand where I spent 3 nights then a further 3 nights in Singapore, after which I flew to Sydney. I spent 5 days there before joining a coach trip as far as Cairns, stopping at various places en route. Before leaving the UK I had bought a flexible Greyhound ticket which meant I could get on and off as the mood took me, so from Cairns I travelled down the centre, Ayers Rock, Kalgoorlie, Coober Pedy, Adelaide and Perth. I spent some time with relatives in Queensland and old neighbours in Bunbury then flew back from Perth to HongKong where I spent 5 days before returning to London. I had booked most of the hotels in advance but sorted out one by phone. All in all I had a fantastic time and wouldn't have missed it for the world, though my neighbours thought I was decidedly odd to be going solo on such a trip.
