I've said it before and I'll say it again, 3 family roller coasters is a bad idea, especially for a park that seems to have trouble with queues and with keeping rides operating all year round. Something that's also been said by many people (including myself) is that they need a people eater, a big indoor dark-ride like Looney Tunes was. If the plan was for 1 family roller coaster and a highly themed dark ride then I'd be like, that's a good idea. But 3 roller coasters feels like someone at the top going, "well we could buy 1 expensive roller coaster, but that'd be expensive and potentially hard to market, but you know what the general public will get excited about... 3 roller coasters." I guarantee that'll be their marketing, not talking about "Australia's first" like they tend to just something along the lines of: "WHAT'S BETTER THAN ONE NEW ROLLER COASTER? HOW ABOUT THREE NEW ROLLER COASTERS?!"
