Conservative activist group Advance Australia has been accused of sexism and poor taste after it released a video of its "satirical superhero" Captain GetUp gyrating and rubbing against a poster of independent Warringah candidate Zali Steggall.

The video, released on the official "Captain GetUp!" Twitter account on Sunday evening, showed the caped conservative crusader in front of a large billboard with Ms Steggall's photograph cropped next to a photograph of Opposition Leader Bill Shorten.

Captain GetUp - who is named after his nemesis, the left-wing activist group - is seen rubbing himself against Ms Steggall's face to a soundtrack of pacey electronic dance music. The video has since been removed.

"I think there is a level of sexualisation with that, which is inappropriate," Ms Steggall said.
