I was up there a month ago, on low tide, try get to the flats at the end of coal and candle creek, can be accessed by a walking track near akuna bay, here's the Google maps link of the flats https://maps.app.goo.gl/hKFSnJ6NDUwjtnfcA
There are heaps of whiting, bream and flathead around here, I found the most success using a Berkeley honeyball 38mm lure and yabbies. If possible the flats in yeoland bay are amazing but not sure if they are accessible by foot.
There's also an odd abundance of squid around here as I had squid following my baits up so might be worth throwing a squid jig around the deeper bits.
Good luck 🤙
