Thanks all for the help, is it worth buying a yabby pump and using as bait? I have seen some YouTube videos but never done it or used them as bait? Sounds like the perfect thing to do with my kids tbh!
also, I do have a 4m kayak, is it worth paddling that down the river to what on Google maps looks like oyster beds and flicking some soft plastics or live bait around them?
thanks again!
