Actually getting to Oz/NZ - help!

OK, one option for our travels would be 4.5 weeks in Oz, 4.5 weeks in NZ and a few days in Dubai.

How would you say would be the best way to physically acheive this?

We'd like to do the East Coast in Oz (not sure about Cairns as it's far out but at least between Melbourne and Brisbane (either direction or a return journey, preferably start in Brisbane though). All around NZ (probably start Auckland, end Christchurch). Dubai is easy as we have a friend there and could be considered a stopover.

Thanks!

Some of the best parts of australia are north of brisbane in my opinion.. barrier reef, fraser island and whitsunday islands... its worth the effort to get up there if you can

From reading the travel guide i bought, i would very much like to get to the Whitsunday Islands if we can, they don't seem to far north of Brisbane..well, not in comparison to Cairns at least!

Yuo might want to look into getting some cheap flight with jetstar or virgin blue that might allow you to see more up north
