Jelly wobble

Came across several of these on the beach at Maroochydore. They look like enormous fried eggs at first. I've been studying alleged jellyfish identification websites, but so far haven't quite got there. They look different when they're not stranded on a beach.

These sorts of jellyfish are often called 'snotties', I gather. But there's been some excitement in recent times among jellyfishologists, with new and rediscovered species turning up. Could it in fact be the Cambione Cookii - the so called 'Cookie Monster' jellyfish, recently rediscovered after 100 years?
