Pennicott Wilderness Journeys shared the footage to Facebook, summing up the excitement of those on board with the words, "this is just a little bit awesome."
The post added, "Skipper Robert Pennicott found this mum and bub having fun in the Wilsons Promontory Marine National Park today. What a wonderful experience."
