We're going to Port Douglas for 4 nights in mid November, then on to Cairns for 2 before flying to Sydney. Apart from one or two trips to the GBR (probably with Wavelength), is there anything anyone can recommend we should do? I've been on the skyrail to Kuranda and the train back so I don't think I want to necessarily do that again. In particular, what is there to do in Cairns? I think I read somewhere that there are really lovely botanical gardens there. Has anyone been?
