Depends on how far you are willing to travel, but you have heaps of options around that area. Some of the obvious spots would be checking out Wellington point jetty, taking a walk out to King Island, having a look around Lota. Really depends on what you want to catch, whether you want to eat it and how close it needs to be.
Quick drive around should reveal a few good locations, or a bit more info and maybe we can narrow it down a bit.
