The northern shore of French Island has one of the most extensive areas of saltmarsh and mangrove communities in Victoria and the mudflats are of State geomorphological significance. The seagrass beds are nursery areas for fish, including commercially and recreationally important species such as King George Whiting, Bream and Mullet. The area is especially significant as feeding habitat for the 32 species of migratory waders found in Western Port. The waters around Barralier Island, one of the bay's 13 high tide roost sites, are particularly sensitive to disturbance. Precautions
For your own safety, only undertake activities appropriate to your skills and abilities. Take all necessary precautions, be aware of changing conditions, and watch for potential hazards, such as rips. A number of Victorian marine animals are potentially harmful if not treated with respect and care, so ensure that you familiarise yourself with these species. Sunburn and hypothermia are also potentially harmful but easily avoided. SCUBA diving is a potentially high risk activity and should only be undertaken by appropraitely qualified people that have completed recognised training and certification. Victoria's cool water environments can be extremely challenging to those used to diving in warmer waters so ensure that local knowledge is sought before undertaking a dive in a new location. Dive charter operators can provide some of the best advice on diving in Victoria. |
