Port Phillip is home to an amazing array of wildlife. When you see dolphins, seals or whales, make sure you give them plenty of space. Never approach closer than 100 metres and leave them alone if they show signs of agitation such as diving or rapid changes in direction.
At the Ticonderoga Bay sanctuary zone (located north-west of Portsea, near Point Nepean), vessels cannot approach dolphins and whales any closer than 200 metres. More information is available from the Department of Sustainability and Environment.
