Hi John,
Yes I have just recently lost big fish to local Sharks in Moreton bay.
I have been fishing the same spot for nigh on 55 years and the sharks in the 60's were really bad and took a lot of grassy sweetlip off us at the time.
Just this year one morning I had 3 under the boat and they were waiting for us to hook a fish.
They got one big cod for sure and possibly another cod that I did not see.
Had a good feed on board so went home after that.
Have fun Haji-Baba.
