Activist group GetUp aims to double its number of volunteers from the last election and issue how-to-vote cards in 29 seats in a bid to promote health and climate on the political agenda.
Thirteen parties and candidates featured on the group's election guides released on Saturday include Labor, the Greens, Centre Alliance and Derryn Hinch's Justice Party.
GetUp boss Paul Oosting told AAP he hoped to be able to endorse the policy platforms of Liberal and Nationals candidates in future elections.
But the Coalition parties were currently too "beholden to the hard right" and failed to properly address clean energy and reducing emissions.
Liberal frontbencher Peter Dutton, whose seat of Dickson is being targeted, said GetUp lacked credibility.
"I've seen some polling on GetUp in my seat and their net favourability is through the floor, so I think people at this election have worked out what GetUp is about," he told Sky News.
"They are an extreme left-wing advocacy group ... and I think people have had a gutful of GetUp."
GetUp will have at least 1800 members handing out almost 800,000 guides at 335 voting booths on May 18 in the group's "most ambitious campaign ever", according to Mr Oosting.
GetUp's cards include several ways to vote on a particular issue.
The electorates being targeted are: Dawson; Dickson; Moncrieff; Menzies; Flinders; Fremantle; Kooyong; Corio; Cook; Hughes; Robertson; Warringah; Cowper; Hume; Wentworth; Cunningham; Macquarie; Newcastle; Page; Canning; Pearce; Canberra; Bean; Fenner; Boothby; Grey; Mayo; Clark; and Franklin.
The group named independents Anthony Pesec (ACT Senate), Julia Banks (Flinders), Susan Moylan-Coombs (Warringah), Zali Steggall (Warringah), Oliver Yates (Kooyong), Huw Kingston (Hume), Andrew Wilkie (Clark), Rob Oakeshott (Cowper) and Kerryn Phelps (Wentworth) as candidates committed to strong climate and health policies.
