for those of you who know the East coast better than I do (which isn't difficult), here is 2 options for you: 1) from cairns, travel overland to brisbane, then fly the remainder of the coast to sydney.
We would like to take our 6 and 10 year old with us to one of the glaciers, Franz Josef or Fox. We would like to incorporate, if possible a short glacier walk which my 6 year old could do. Does anyone have any info or suggestions on where we could do this?
