Wow i have an itinerary for once. I also have aching feet and a cracking hangover as i write this. It seems Sydney has quite a good selection of pubs and people wanting to have a drink with you :-)
I seem to have to have a plan, as i have so little time (2 months) in this huge country - it's easily bigger than SE Asia after all. So:
Sydney
Blue Mountains
Canberra
Snowy mountains
Melbourne
Tasmania
Melbourne
Adelaide and surrounding area
Cairns
East coast between Cairns and Sydney
New Zealand
Of course shares can go up as well as down.
