Watched a vid on attracting garfish in Australia (Port phillip bay Melbourne)
I lived in Cheltenham Victoria.
They were 'Chumming' the water with groundbait similar to what we do in freshwater.
Their garfish have their mouths above their beaks,where as ours have a beak that opens.
I camped on The Lizard in Cornwall a few years ago and caught a few off a dock wall.
