Labor is shaking the donation can for an advertising blitz while Climate 200 had a staggering boost after a Liberal candidate's climate comments.
National secretary Paul Erickson emailed party faithful on Friday morning asking for more than $43,000 by Saturday night "to stay on track with a major digital advertising push".
The money would go towards promoting Labor's health pledges as it seeks to promote itself as staunch supporters of Medicare in contrast to the coalition, regularly attacking Opposition Leader Peter Dutton for his time as health minister.
"This is make-or-break stuff. We're up against huge spending from the Liberals' biggest backers, but we know that when our message lands, we win," Mr Erickson said in the email.
"This election is going to be decided by a few hundred votes in a few battleground seats and missing this target could mean we pull back just when we need to double down."
The federal Labor Party spent almost $100,000 on Facebook ads in February that have been viewed millions of times, publicly available Meta advertising data reveals.
The ads have predominantly been seen by younger audiences aged between 18 and 44.
The key battleground state of NSW received the bulk of the ads targeting the opposition leader, purporting that the cost of living would be worse under Peter Dutton, while smaller spends target Tasmania with local messaging.
The Liberals' federal Facebook page has also spent thousands of dollars in the last few days targeting marginal Labor seats with ads attacking the local MP for overseeing food price increases alongside Prime Minister Anthony Albanese.
It comes as the Climate 200 fundraising vehicle that backs pro-climate action independents raised more than $1 million from more than 3300 donors, after emailing supporters with comments from Liberal Andrew Constance walking away from climate commitments.
It seized upon the comments from the Liberal moderate and former NSW minister to attack the coalition as becoming more extreme against climate change under Mr Dutton.
Climate 200 has also launched an ad campaign focused on Clive Palmer alongside Donald Trump after the mining billionaire started a political party aimed at copying the US president's policies.
The spend for each ad as of Friday sits in the hundreds of dollars, with some less than $100.
