Well forget about the bait or the lego, got one better.
I can actually still remember when I was a kid fishing inside the breakwall near the back of the co-op at Nelson bay catching slimies with no bait, just a hook.
They was a massive school were in there in a frenzy taking anything shiny.
End up catching 75 in about 30/40 minutes, great fun, I dont think I even kept any as being a kid of about 10 years old it was just fun catching fish with just a hook
That was back in the day when the wall was shorter, used to get dolphins & other creatures in there back then to.
I recall @Scratchie saying he had a similar experience when the Kingie cages broke up at Broughton & the kings were just taking the shiny hooks with no bait
