I try to not fish lures off any wharf, as most wharves on the parra river have been over fishe, just look at google maps and explore some spots that look they are worth a flick around. Start by using softplastics either squidgy bloodworm wriggler, zman grubz in bloodworm colour too or also Gulp grubs in watermelon or pumkin seed are awesome try with a 1/10th or 1/8th jig head and fish it slowly with some long pauses, should get into some flathead hopefully. Try the shorelines along iron cove. goodluck
