"I think I will fly up north as far as the barrier reef and back. I just have to get my hands on some maps to see if that is possible to do within a month..."
From Sydney? The start of the Reef, around Lady Elliot Island, would only be around 700 nm north of Sydney? I think I could do that on a push bike in a month!!
Butair. I suggest you make contact by PM with some of our Aussie PPRuNers and identify exactly where you want to go - otherwise we'll be wandering all over Australia, from Abbeywood to Zilzie. I'm sure you will find our Ozmates very helpful.
