There's a lot of questions, like What meal? Would you prefer QS or TS?
Off the bat, in park I'd recommend Cosmic Ray's for some good park food. Its quick service and has a ton of options for any picky eaters.
I personally love Casey's Corner on Main Street, and Pinocchio Village Haus for the atmosphere.
If you're looking Table Service, Crystal Palace is fun as is Liberty Tree Tavern. You're from Australia, and its very traditional American holiday like fare. I hope this helps!
