Marc,
Add this to your list of must do's if you head up our way...
https://www.discoverthedaintree.com/aerial-walkway/
There is a bit of a 'foody' trail up on the Tablelands, couple of dairies, local cheeses, coffee plantations & tea plantation..
Tons & tons of things to do & see up here mate... give us a yell if your stopping in Cairns, maybe catchup for a beverage or two & if the skies are nice, maybe some stargazing...
Cheers
Carlton
