I went to Dreamworld recently and agree that the ride capacity was terrible and most of the coasters and rides had only one staff working them.
Apart from Tower of terror and Eureka Mine coaster the other coasters weren't that crash hot.
In particular the ThunderBolt which would have to be the worst coaster in the world,very rough and braking alot.This is sad as when i went to Dreamworld 15 years ago it was a Great coaster.
I wonder if mangement of Australian theme parks Realise how bad some of our coasters have become.Especially compared to other coasters overseas.Not only in Building coasters but updating and maintaining them as well.
