I see that Australia is (probably) reopening. I have a window of March-September 2022, and I'm thinking of trying to schedule a GBR liveabord. I don't know much about GBR diving, so I'd welcome feedback. I see Mike Ball and Spirit of Freedom are both well regarded. Any other hints for what could well be a one time trip? I have dove a fair amount in the Caribbean, and two weeks (back to back) in the Red Sea. I guess I am looking for something moderately high end, say on the standard of Explorer Ventures or Aggressor Boats. I'm a photographer, and not a deep / deco diver.
