Dressed in orange tights and a grey cape, Captain GetUp has arrived in Sydney to come to the rescue of Liberal MPs at risk of losing their seats in the May federal election.

The self-styled "truth crusader" is the creation of conservative lobby group Advance Australia which has been set up to counter the campaigning of progressive group GetUp.

"After 14 years of secret backroom deals I have finally been let out of GetUp HQ!" the mock superhero declared on Tuesday morning in Manly, where former prime minister Tony Abbott is battling to save his Warringah seat.

"I'm Captain GetUp and I'll be travelling across the country over the next few weeks educating voters about all the clever tricks we use to influence an election."

Fret not citizens of Australia, after 14 years of secret backroom deals I have finally been let out of GetUp HQ! I'm Captain GetUp & I’ll be travelling across the country over the next few weeks educating voters about all the clever tricks we use to influence an election #auspol pic.twitter.com/PpvuiS4EaI — Captain GetUp!

The character comes with his own Twitter, Instagram and Facebook accounts.

However, the use of GetUp in his name is already proving problematic for the mock superhero.

PUNTER: so you’re from GetUp?



CG: er, no.



PUNTER: So why are you called Captain GetUp?

From a campaigning perspective 'Captain GetUp' seems a terrible idea and will surely only raise the profile and influence of the actual GetUp campaign https://t.co/xxStN3p7z9 — William Summers (@william_summers) April 8, 2019

Warringah is one of at least six seats held by Liberal MPs being targeted by GetUp and its army of volunteers.

The left-wing lobby group has been active in Sydney's north shore electorate for weeks, holding various events including a mock early retirement party for Tony Abbott.

Advance Australia was formed by prominent businessmen to rival GetUp and is focusing its efforts this election on saving those seats.

In a recent update to members, Advance Australia national director Gerard Benedet said they had listened to their wishes to help "mainstream candidates" campaign in marginal seats against independents or "non-mainstream" incumbents.

"We've already been hard at work campaigning for mainstream values and freedoms in target seats across the country," Mr Benedet wrote in the email sent earlier this month.
