Club weekends we are allowed 10 per species max for the weekend, except where MAF rules apply .
Catching snapper limits happens while surf casting and rock fishing. But how many catch there limits on 2 consecutive days? your allowed to, but if you have say 18 snapper in the bin when heading home from the bop at least 9 will need to bagged and tagged for the previous day... but as the club limits us we don't fall into this potential problem if picked up by MAF.
A few times a year there have been club members who weigh in 20+ fish for the weekend. The fish are kept on ice and looked after - all fish gets divided up and eaten.
Inter-clubs a lot of fish can be caught over a weekend and we have all seen some waste there, especially with shark species.
