How to move Canada Geese

My friend has a lake in her garden with an island.A pair of Canada Geese took up residence and produced eggs which hatched.All fine until they took the whole family into a neighbour’s paddock where she has a swimming pool.The neighbour does not want them in her pool and my friend would like to encourage them back into her garden, but is not sure how to.She could coax the goslings back through the fence but the adults would need to fly over it and she is scared of them attacking her if she tries to move the goslings.

Any suggestions?
