What is the best Gold Coast theme park?

Coming over from NZ & we are taking our sons (9 and 8) over to Gold Coast in October and it’s been over 20 years since I’ve been there. What are the best theme parks now? Both kids are fairly interested in tv/films so I’m thinking definitely movie world. We’re only going over for a week so we won’t get a chance to do all of them. But I’m thinking based on their ages I could narrow down the best ones.
