This is a dive in the middle of the Port Phillip Heads. The Plateau is a huge rocky platform located in approximately 16 metres of water, and winding its way around the edge of this platform is the Entrance. This is the deepest water in Victoria, originally part of the river Yarra. Depths at the bottom of this area are between 40 metres and 100 metres. The slack water period here is short, hard to pick and the currents are a little unpredictable. There is also the problem of the dive site being located smack bang in the shipping channel and diving here is only possible when sea conditions, the tides and shipping timetables allow. Despite all that, this area is amazing, with some fantastic rock formations sheltering an amazing array of sea life.
