I think you blokes are carrying on a bit here!
Couple of reasons:
1. I don't think this year is any better then others, and it has been a cracker of a season.
2. Most blokes can't catch 5 snapper
3. The current regulations are more than adequate.
If the regulations are tightened up much more in will become pointless going out to catch a feed. And finally on tagging big snapper and throwing them back; I think you are turning them into shark bait. Yes, they may live for a while, but they are pretty bloody doey from the stress of the capture and are and become an easy target for the sharks.
Leave the current rules alone,
Good fishing
