I just thought it was interesting to hear a view from a veteran marine biologist who studies sharks, i guess it depends on your definition of significant. 16 years to maturity, 16 years since protection, yeah maybe sharks that were young then are reaching maturity and the adult population is getting larger and producing more pups, but that generations of pups hasn't reached maturity in number so with natural attrition factored in even with ideal circumstances the population probably hasn't doubled. Like he said one of the primary indicators is commercial fishing bycatch and that data hasn't changed. This drum line policy could be useful data but so far it is showing 0 GWS captures so thats hardly conclusive.
Anyway, I was against the cull regardless of the shark population. I don't really care about the science because to me its an ethics thing. The science is interesting to debate because there arguably hasn't been due diligence done by the government to establish facts on which to base their decision, but thats all neither here nor there if you want to argue that its inappropriate to kill an endangered and important animal to potentially save 1 or 2 lives a year of people who choose to take the risk of entering the ocean and compound those risks by imitating shark prey and forsaking the use of known deterrents such as shark shields.
