It's called traditional cooperative fishing, a way to communicate with dolphins to get fish, exists or at least existed in places like in WA in Mandurah estuary. Traditional owners from different places used similar techniques tapping the water and dolphins would chase fish in. If it happened in one spot it probably did and may still happen all around Australia.
It does happen in other parts of the world, like Brazil between bottlenose dolphins and fisherman targeting mullets, and how it used to happen in Australia with also killer whales and whalers targeting humpback whales.
But one of the places where dolphins and human cooperation is more representative is in the Asian country of Myanmar, where the practice is still seen today.
