Dozens of anti-mining protesters have targeted Prime Minister Malcolm Turnbull's Sydney home to rally against taxpayer funding for the Adani coal mine.
Activists chanted, waved placards and threw beach balls at the colourful Stop Adani rally, held at Lady Martins Beach in Point Piper on Sunday morning.
The group says the government is exploring the possibility of using the Export Finance and Insurance Corporation (EFIC) to help the Indian mining giant's project.
It comes after Queensland Premier Annastacia Palaszczuk vetoed an almost $1 billion concessional loan through the Northern Australia Infrastructure Facility.
Businessman Geoff Cousins, a neighbour of Mr Turnbull's, said the lobby group was responsible for Ms Palaszczuk's decision and pledged to also stop the "back door" EFIC method.
"Not only because that mine will greatly affect the (Great) Barrier Reef and contribute enormously to global warming ... but also because Adani itself is a corporation rotten to the core," he told the crowd.
After a similar protest at the Gold Coast office of Steve Ciobo this week, a spokesman for the Tourism Minister dismissed the suggestion about EFIC as "complete rubbish".
"The minister can not 'order' EFIC to fund loans to resources companies on its commercial account," the spokesman told AAP.
"He can not order them to fund anything on the commercial account - it's completely at arms length. And there are no proposals for Adani to receive funding on EFIC's National Interest Account."
