Activist group GetUp! says it won't be spending one dollar of foreign money on its campaigning during the federal election.
GetUp! chief Paul Oosting says the party has raised $12.54 million over the past year, based on an average donation of $20.
Critics of the organisation say it is relying heavily on foreign donations as it targets coalition candidates over climate and other policy areas.
Mr Oosting said foreign donations represented about 0.5 per cent of the organisation's annual take, mainly from global environmental foundations.
"Zero dollars in total in foreign money will be spent on our federal election campaign - this is a people-powered effort," he told Sky News on Monday.
He said the organisation was targting former prime minister Tony Abbott in his Sydney seat of Warringah over his efforts to "stop the transition to renewable energy", but had yet to determine its how-to-vote material.
It was likely four candidates, but not Mr Abbott, would be promoted to voters based on their strong stance on climate policy.
