You will need a 4WD to get off the barge as it drops you on the beach. and generally where the sand is nice and soft.
You'd be surprised what you'll catch landbased if you put in the effort at the right time. Get away from the wrecks though, never caught a decent fish within cooee of the joint. Its the only wreck in the hole bay that doesn't produce decent fish. Too much boat traffic i think.
