yeah i was there on tuesday, there were a quite few, but they wern't trapped they were just passing through they did seem to hang around that general vicinity for a day or two though. i live nearby, they seem to have left now. I stopped by after work and there was a couple of fishos on the wharf soaking baits in the harbourside and said that they had caught a rat or two eariler in the day but none in the bath even though they had tried.
just spoke to a nieghbour who saw fisheries officers give people fines for fishing in the pool side of the shark bars. bit harsh if you ask me.
