The hour-long protest was on Saturday morning (June 30).

The silent vigil showed the significant impact of coal minues and coal powered stations have on climate change and global warming, spokesperson Harry Creamer said.

"Today is no new coal day. We are calling for no new coal mines or no new coal powered stations in Australia," he said.

"There is a significant link between coal and climate change and global warming.

"Coal is the biggest contributor to pollution and is also a major health issue because of the bad pollution linked with it.

"There is also the costly rehabilitation that coal companies have walked away from; there are enormous costs to clean up these areas.

"Coal has taken us out of the darkness but we are in danger of moving back into that darkness."

Mr Creamer said countries around the world are doing much better than we are, in relation to investigating and implement alternative power sources.

"Our concern is focussed on what Australia is doing," he said.

The spokesperson said the federal government party room had, this week, debated about whether to fund new coal powered stations.

"And don't forget that both major parties support the Adani coal mine in Queensland too," he added.

Mr Creamer said it could not understand why the current federal government would not look at winding down coal mines in favour of alternative power sources.

He said a recent Lowy Poll found that 84 per cent of Australians are in favour of renewable energy rather than coal.

"Even the majority of Coalition voters favour renewables over coal. This is a government that is not listening to its own voters," he said.

"We want to say no to the Adani coal mine, build solar not coal and say no to any new coal powered stations.

"There is a growing concern that Australia is not doing enough about reducing the reliance on coal mines.

"Support for climate change is resurging," he said.
