Captain GetUp appeared in Tony Abbott's seat of Warringah on Tuesday, highlighting GetUp!'s supposed support for Labor and the Greens and criticising its acceptance of foreign donations.

The caped character was created by Advance Australia, which was launched in November to champion conservative causes.

He introduced another conservative character, Freddie Foreign Money, to his social media followers this morning.

Advance Australia national director Gerard Benedet said Captain GetUp had been "a great success" in building awareness of "GetUp!'s radical left-wing agenda".

While many people have made fun of Captain GetUp online, Mr Benedet said there was no doubt he had highlighted some of Advance Australia's causes.

"He's designed to be a political satire, there's no doubt about that," he said.

"People joining online, as I've seen, are making funny memes about the captain, and that's a good thing."

Mr Benedet said Captain GetUp and Freddie Foreign Money would be travelling around Australia over the next six weeks.

"I think you use many different tools to achieve strategic outcomes and what we're trying to do here is wake people up to GetUp! and their radical agenda and what it means for Australia's way of life and how it's being changed," he said.

GetUp! dismisses 'stunt' despite deploying caricatures

Captain GetUp has already inspired a plethora of memes and a fake Twitter account.

"I thought Captain GetUp was promoting a new Australian breakfast cereal," one social media user wrote.

GetUp! national director Paul Oosting dismissed Captain GetUp as a "silly little stunt" — despite GetUp! using caricatures of Tony Abbott and Peter Dutton at its own stunt in suburban Adelaide this morning.



Mr Oosting said Advance Australia would not deter members from campaigning on climate action in the southern Adelaide seat of Boothby.

GetUp! is targeting the seat in a bid to oust conservative Liberal MP Nicolle Flint.

"It's giving people a lot of laughs on Twitter as this sort of right-wing splinter group from the Liberal Party is roundly mocked for their attempts," Mr Oosting said.

"I guess it's satire or something akin to that, but no, I don't think it'll have any real impact."

Ms Flint was first elected in 2016 and holds Boothby — which is South Australia's only marginal federal seat — with a 2.8 per cent margin.

Peter Combe sings for GetUp!

Children's entertainer Peter Combe joined GetUp!'s campaign in Glenelg this morning.

He sang his famous 1988 song Newspaper Mama as well as a new one called Sun Comes Up, Sun Comes Down about climate change.

"We live in an extraordinary, beautiful place and we can keep it like that if and only if as a nation we choose to," Combe told a small crowd at the protest.

"It follows from this that we need political leaders who not only accept the science about climate change but put policies into place that will rapidly reduce greenhouse emissions."

Mr Oosting said GetUp!'s focus was not on electing Labor candidates like Nadia Clancy in Boothby.

"Our focus is on removing the hard right from Parliament and making sure their corrosive impact on stopping action on climate change [and] stopping our transition to cheaper affordable renewable energy is removed from Australia's body politic," he said.

He said GetUp! planned to make 100,000 calls to Boothby voters during the election campaign.

He said the group's 700 South Australian volunteers had already called 25,000 people.

Prime Minister Scott Morrison had been expected to call a May 11 election last weekend but did not make any announcement.
