Anti-coal lobbyists have staged a protest outside an ANZ branch in Melbourne in solidarity with the activist behind the Whitehaven Coal hoax.
Protesters from Quit Coal played dead on the floor of the ANZ branch in Melbourne's Bourke St Mall, to be carried out on stretchers by members dressed as paramedics.
The action comes days after Jonathan Moylan, from the anti-coal mining group Frontline Action Coal, sent a press release to media outlets claiming the bank had pulled its $1.2 billion loan to miner Whitehaven Coal.
The hoax temporarily wiped $314 million from the value of the company.
Quit Coal spokeswoman Chloe Aldenhoven said it was important fellow activists supported Mr Moylan.
"We're here in support of Jonathan Moylan and his action which brought to people's attention that ANZ have been funding coal projects that are fuelling catastrophic climate change," she said.
"We think it was an important act of civil disobedience and the costs incurred by day traders are insignificant when you consider the cost of cleaning up climate disasters and the cost to the community of the droughts and bushfires we've seen in the last few years."
Mr Moylan last week said officers from the Australian Securities and Investments Commission (ASIC) had raided his camp in northern NSW and seized some of his property including a phone and laptop.
ASIC is investigating if any laws were broken.
