There’s a weird and wonderful underwater world right on our doorstep in Port Phillip Bay – and much of it is only a few metres below the surface. Tiny Portsea, on the tip of the Mornington Peninsula, is Victoria’s most diver-friendly spot, so this is where I head to begin some underwater exploration. Gary Grant, of Bayplay Adventure Tours, has been running guided dives and PADI courses here for 12 years and says shore diving in the temperate waters around Portsea comes as a Seahorse nestled in the surprise to those who have only experienced tropical waters. Sea dragon with eggs, captured in the lens, so exquisite coral, a burst of colour “I did two thousand dives in the tropics before I moved here,” says Gary, “But the one thing that got me here is how unusual the diving is — the weirdness and unique marine life.

Detailed numerical models have been developed to examine tidal hydrodynamics, wave transformation and sediment transport processes. Wave transformation modelling has incorporated the tidal hydrodynamics to investigate the impact of tidal streams on wave propagation. The combined impacts of wave refraction and diffraction have been simulated using a Boussinesq-type wave modelling program. Boussinesq-type equations present the most complete solution to wave transformation that is available and have been used to predict accurately wave evolution across large basins, wave breaking over irregular topography, wave –structure interaction and wave-induced current patterns, among many other advances.

    PORT PHILLIP BAY CHANNEL DEEPENING PROJECT ASSESSMENT under ENVIRONMENT EFFECTS ACT 1978 Minister for Planning November 2007 ii ISBN 978-1-74208-165-6 Assessment: Port Phillip Bay Channel Deepening Project iii FOREWORD This Assessment of the environmental effects of the Port Phillip Bay Channel Deepening Project (CDP) completes the assessment process under the Environment Effects Act 1978 for this proposal. It also constitutes the Assessment Report required as part of the accredited assessment process under the Commonwealth’s Environment Protection and Biodiversity Conservation Act 1999. This Assessment process has entailed an unusual intensity of effort on the part of the Port of Melbourne Corporation (PoMC), as the proponent, as well as by agencies and submitters in response to the 2004 Environment Effects Statement (EES) and the 2007 Supplementary Environment Effects Statement (SEES), and the two inquiries appointed under the Environment Effects Act. I acknowledge these efforts and thank all those who have contributed to the process, including PoMC, submitters and most recently the members of the “SEES Inquiry”, including Dr Allan Hawke as the Chair, and Ms Kathryn Mitchell and Dr Mike Lisle-Williams as Members. I particularly wish to thank the members of the Independent Expert Group (Dr Graeme Mitchell as Chair, and Dr John Parslow, Prof. Mick Keough, Dr Kerry Black and Mr Nick Bray), for their advice during both the preparation of the SEES and the SEES Inquiry process. These various efforts have assisted in ultimately achieving a comprehensive understanding of the potential environmental effects of the CDP, in terms of magnitude and likelihood, as well as appropriate management responses.

  • Across the Heads GREG MULLER: Welcome to a Summer by the Sea
    Across The Heads GREG MULLER: Welcome to a Summer by the Sea podcast. I'm Greg Muller. I'm at the Queenscliff ferry terminal on the Bellarine Peninsula. We're about to board the Searoad Ferry across to Sorrento. Summer by the Sea is run by Coastcare Victoria with the aim of inspiring people to learn more about this state's beautiful coastline and in turn find out what you can do to protect these unique environments. Just waiting for the cars to load, and then we'll make our way onto the top deck. It's an open deck, there's an inside area too, but on a day like today, why be inside? And the views are fantastic. With me is: MARK RODRIGUE: My name is Mark Rodrigue I'm the Program Leader for Marine and Coasts with Parks Victoria, and it's a great pleasure to be welcoming you here in this virtual way down to Port Phillip Heads Marine National Park. It's a beautiful, slightly sunny day, a little bit overcast, but it's a fabulous day for seeing a little bit about the amazing cultural and natural values of this particular part of the world. It's a very rich area from Aboriginal history to the geology of the area, through to our fantastic Marine National Park that we're going to talk a bit about during the course of our journey. So strap yourselves in and let's go for a bit of a ride on the ferry. GREG MULLER: And I should just say, we're traveling from Queenscliff to Sorrento.

  • 28 to Accompany Australian Notice to Mariners 498/2004 28. MARINE PROTECTED AREAS 1. Australia Has Established a Number of Comm
    To accompany Australian Notice to Mariners 498/2004 28 28. MARINE PROTECTED AREAS 1. Australia has established a number of Commonwealth, State and Territory Marine Protected Areas (MPA), which comprise any area of intertidal or subtidal terrain, together with its superjacent waters and associated flora and fauna, which has been reserved by legislation to protect part or all of the enclosed environment for conservation, scientific, educational or recreational purposes. 2. This notice contains a listing of the significant marine protected areas which exist in Australian, the external territories and Antarctica. Mariners should be aware that areas such as marine and aquatic reserves, fish habitat and management areas, specific types of aquatic sanctuaries and historic sites (see Notice to Mariners No 21), may also exist. National parks may also have a marine component in the intertidal area. A full listing is contained in the Collaborative Australian Protective Areas database (CAPAD) can be found at the Department of Environment and Heritage website: www.deh.gov.au/parks/nrs/capad/index.html.. 3. Entry to waters south of 60° S requires contact with the Australian Antarctic Division or other appropriate Antarctic Treaty Governments for approval prior to entry. 4. The Great Barrier Reef Marine Park (GBRMP) covers an area of approximately 345 400 km2 along the east coast of Queensland from Cape York, south to Rules Beach, a point between Agnes Water and Bundaberg. The GBRMP extends eastward from the MLW to beyond the eastern edge of the Great Barrier Reef. The entire Park (including the waters, airspace, Commonwealth Islands, sea bed and sub-soil beneath the sea bed) is considered a MPA and restrictions may apply to access and or use both continuously or on a seasonal basis.
