Beach Litter Surveys 2004–05 Summary Report BEACH LITTER SURVEYS 2004–05 SUMMARY REPORT Publication 1021 November 2005 1.

The EPA Victoria again commissioned Keep Australia overall number of litter items, mainly cigarette butts Beautiful Victoria (KABV) to investigate litter on and small plastic items, remained steady. twelve Port Phillip Bay beaches during the summer of 2004–05. Regular beach cleaning by councils is helping to control beach litter. There are further opportunities for councils and beachgoers to keep their local beach clean. As beachgoers we are all responsible for the condition of our beaches. Beachgoers must also play their part in protecting this special environment by disposing of their litter in bins provided or taking it with them when they leave 2. KEY FINDINGS 2.1. Visual Ratings KABV rate each beach for visible litter. Ratings are between 0 and 10, with zero representing no litter and 10 representing a site covered in litter. Figure 1 shows that in 2004–05 the beaches had less visible litter than in the previous year. The trend has continued to improve over the past six years with the beaches looking cleaner each year.

    TANGAROA BLUE OCEAN CARE SOCIETY 2010‐11 Victorian Surf Coast Marine Debris Project Report Heidi Taylor, Wally Smith “Pollution is a symbol of design failure.” William McDonough, American architect. Tangaroa Blue Ocean Care Society PO Box 757, Port Douglas, Queensland, 4877, Australia www.oceancare.org.au Introduction Tangaroa Blue Ocean Care Society (TBOCS), www.oceancare.org.au is a non‐profit organisation registered on the Department of Environment’s Register of Environmental Organisations. In 2004 TBOCS founded the South West Marine Debris Project (SWMDP) to focus on the issue of marine debris in the south west region of Western Australia. The aim of the project is to find ways of reducing the amount of marine debris making its way into our oceans and impacting marine life. In 2010 TBOCS launched the Victorian Marine Debris Project with the support of Surfrider Foundation Australia and with funding from a Caring for our Country Grant. The aim of the project was to remove debris, identify those items impacting the Victorian coastline, contributing to the National Marine Debris Database and engage communities into a national marine debris project. Over 5,000 TBOCS volunteers have collected more than 650,000 items of rubbish from beaches around Australia and New Zealand since 2004. In its seventh year of the Australian Marine Debris Initiative, data on what is making up the debris and where it is coming from is helping to create strategies to reduce the amount of rubbish in local waters. In every square mile of ocean it is estimated that there are over 46,000 pieces of plastic, resulting in the deaths of more than 1 million seabirds and 100,000 marine animals every year.
