Media Release: New report details damning environmental destruction by Dendrobium Mine

Wollongong, New South Wales — Confronting images of recent environmental destruction by South32’s Dendrobium Mine have come to light, showing cracked streams and rockfalls within the Special Areas of the Greater Sydney Water Catchment. The mining multinational published its Longwall 17 End of Panel Report (1) earlier this year, documenting the immediate environmental impacts of this particular area of mining in Area 3b. 

Detailed in this report are impacts on streams, creeks, upland swamps, access roads, water losses, as well as documented Aboriginal heritage sites. The report documents 40 identified new surface impacts, 75% of which were on “natural features”.

South32 recently withdrew its application for a 20 year extension to the Dendrobium Mine, but will continue to conduct longwall mining within the water catchment for several more years.

Protect Our Water Alliance (POWA) spokesperson Dr Rada Germanos said “This report provides us with real-time evidence of the horrific damage that South32 is causing within our water catchment. It is incredible to read such a long document that lists cracked stream after cracked stream, dry swamp after dry swamp, and realise that all of this destruction has been approved by the Department of Planning.”

“Furthermore, only two of the five documented Aboriginal heritage sites were visited in the post-mining survey. First Nations people have said time and time again that longwall mining affects the cultural integrity of the landscape, and here we see an incredibly poor effort by South32 to even bother to acknowledge their destruction of these places.”

“While water drinkers in Sydney and the Illawarra are relieved that the expansion of the Dendrobium Mine will not go ahead, we remain deeply concerned that damage to our water catchment continues every day until the mining ceases.

This consent to destroy has been provided by successive NSW Governments. It is simply not good enough to allow multinational companies to trash these ecosystems, and document their destruction in these dry, detached reports. As the 2023 State Election draws closer, we ask, do the Labor or Liberal parties care enough about clean drinking water for the 5 million people of Greater Sydney to overhaul our planning laws, and stop this destruction by stopping mining in our water catchment?”

Dendrobium Damage Update #4 – more cracked rocks

South32 has finished mining Longwall 17 in “Area 3b” in the Dendrobium Mine, which of course is on unceded Dharawal Country, and just north of the Avon Reservoir.
Your faithful friends here at POWA have trawled through the End of Panel report, and distilled some Dendrobium Damage for you. Spoiler alert: longwall mining is highly destructive, and South32’s contractors only appear to have surveyed a small part of the undermined (and adjacent) area.

Dendrobium Damage Update #1

South32 has finished mining Longwall 17 in “Area 3b” in the Dendrobium Mine, which of course is on unceded Dharawal Country, and just north of the Avon Reservoir.

Your faithful friends here at POWA have trawled through the End of Panel report, and distilled some Dendrobium Damage for you. Spoiler alert: longwall mining is highly destructive, and South32’s contractors only appear to have surveyed a small part of the undermined (and adjacent) area.


Update #1

The extracted longwall has a length of 1901 metres, a void width of 305m, and a maximum cutting height up to 3.9m.

During the extraction of Longwall 17, forty new surface impacts were identified.

  • Thirty of these impacts were observed on natural features.
  • The remaining ten impacts were observed on built features such as fire roads and other access tracks

Only two out of five Aboriginal cultural heritage sites located within the Subject Area were visited.


In summary — a bloody big longwall, and a suspiciously low number of identified impacts over such a large footprint.

Also, the surveyors identified ONLY FIVE cultural sites in the area – and only checked on 40% of them. We know first nations folks in the Illawarra refute this quantitative, piecemeal approach to evaluating the impact of mining on the cultural integrity of the landscape.

Stay tuned for update #2!
