I’ve never thought of the port. Have snorkelled around ocean bay but never tried a rod. But there were heaps of congers and crays.
Snorkelled around robinhood and a bit of fishing but never really came up with much.
Seen quite a few bluecod and crays whilst snorkelling though.
Out around the points look good but like you say you’d need a boat or Kayak. Might have to tow the inflatable up
