Top catch and it's great to hear the population and size are returning. I hope commercial fishing keeps away from both harbour and Botany Bay. Yes we can see great results from Port Phillip Bay since the commercial side stopped there.
I remember fishing Old mans Hat in the harbour 30 odd years ago. Some of the old timers I was fishing with remember marlin being caught there (very few that is).
Imagine, Marlin land based off Sydney harbour, PRICELESS!
