Cleaning up an old port – what does success look like?

Mr Peter Pfennig1

After over a century of neglect and uninformed development and management the Port River near South Australia’s capital city Adelaide was looking very much the worst for wear. The river was characterised by an almost constant algal bloom with regular dinoflagellate population explosions causing ‘Red Tides’.  Stable rafts of sea lettuce (Ulva lactuca) were a regular feature of the nearby Barker Inlet and Adelaide’s coastal waters during spring. In the 1990s things began to change with discharges being either severely curtailed or removed and a continuing move to better stormwater management.  A Water Quality Improvement Plan was developed by 2008 with support from the Australian Government to set targets and guide efforts.

A Dolphin Sanctuary was established and more recently there has been a move away from heavy industry in the inner Port to commercial and residential development.

Things have changed in the Port River over the last 20 years, but how is it faring now, and what does the community think about their river?

Information about the current environmental status of the Port River will be presented and questions posed – when have we done enough? What will this look like? how will we use our Port river?

About the Association

The Australian Coastal Society (ACS) was initiated at the Coast to Coast Conference in Tasmania in 2004. The idea was floated as a means for those interested in coastal matters to communicate between conferences and where possible take resolutions of the conference to appropriate levels of government.

The idea was discussed further at the Coast to Coast Conference in Melbourne in 2006 and it was agreed that Bruce Thom develop a constitution of a company limited by guarantee that would operate on a national basis.

This plan was accomplished and in 2008 at the Coast to Coast Conference in Darwin the constitution was ratified and an Executive appointed. The company received charitable status in 2011.
