A fantastic place...
Been to:
Brisbane (only very briefly)
Townsville
Cairns (extremely briefly)
Alice Springs (ditto)
Ayers Rock (wow.)
Perth
Adelaide
Melbourne
Sydney.
Awesome, every one.
I spent 2 R & R's there back in the late 60's early 1970's, and again on two deployments while in the USAF for 45 days each time........I like Austrailia and its a very varied country.....lots to see lots to do.....
