I live in Darwin. I am pretty sure that most accommodation has aircon. The following places/activities are good for families:

-crocosaurus cove
-wavepool
-crocodylus park
-museum
-playshack(Palmerston)
-territory wildlife park
-aquaduck (bus that drives into harbour)
-leanyer water park
-the planet (tenpin and kids play centre)
That should do for a start
