Save St Kilda Mangroves

The Spring of our Discontent: The onset of a second springtime of hypersaline leakage from the salt ponds was marked by a range of Direct Actions

- September-November 2021 -

Winter brought rain, and with it calls for the salt brine to be removed from the ponds, to reduce the likelihood of further impacts. When these calls appeared to be falling on deaf ears, and with torrid reactions from some politicians and government agencies becoming more common, community members started undertaking direct actions.

The first day of Spring saw the Citizens' Environmental Cleanup! Thank you Uncle Jeffrey, Yuandamarra and Nadia for your support and blessing. Faith, what can we say? What a classy action! And the excess funds from the "Go Pump Me" crowdfund will be the seed funding as the community looks to install a piezometer network to monitor the shallow groundwater lens under the town - so stay tuned for more information!

When toxic politics resulted in a public verbal attack (on radio) on one of the Alliance scientists, brave rebels from XR took time out from their larger concerns to start an #IStandWithPeri social media action, and so many wonderful people joined in...

And a huge "Well Done" to kayakers George, Sue, Albert and Leonard, who love Barker Inlet and who undertook a magnificent "Canoe Doodle to Save the Mangroves"

But we are not done yet. Earlier this year, a Community Vision Workshop was held to envision the future of the coastline along the southern parts of the Adelaide International Bird Sanctuary, Winaityinaityi Pangkara. The report from that workshop is due out shortly. Keep coming back to this website for updates and remember that there are even more updates, live as they happen, on our social media feeds.

The St Kilda Mangrove Die-off

What is happening?

Our beautiful tidal wetlands (mangroves and Commonwealth EPBC Act protected saltmarshes) surrounding the St Kilda Mangrove Boardwalk have been sickening and dying since mid 2020.

The nearby decommissioned gypsum ponds were filled with hyper-saline brines. Gypsum, lining the old ponds, had rotted after sitting empty for seven years and now the ponds are leaking and mobilising acidic materials from underneath the gypsum crust.


The SA Department of Energy & Mines regulate all the ponds as part of the Dry Creek Saltfields and the SA Department for the Environment manage the National Park next to the gypsum ponds.

Both departments have allowed this catastrophic impact to continue unchecked, merely measuring the impact, rather than being proactive and starting efforts to halt the ongoing leakage occurring from underneath the irreparably damaged gypsum crust.

The St Kilda Mangroves need your help right now

Please sign, and share the petition for the South Australian Government to act immediately to minimise the damage done to the St Kilda Mangrove Forest through the continuing leaking of hyper-saline liquid from the adjoining gypsum ponds.

So far the impact continues, no one is admitting it is an ongoing disaster, no one is taking responsibility and the environment is losing ground (and ability to repair itself) daily. [28-12-2020]
