Pauline Hanson blames Tony Abbott for her imprisonment over now quashed electoral fraud charges but the pair have made up in a bizarre staged video posted to the senator's Facebook page, in a move that will spark further speculation the former prime minister is attempting a political comeback.

"Pauline it's good to catch up with you after all these years," Mr Abbott said, making no mention of the brutal campaign he led to destroy her One Nation party.

In a stilted conversation lasting just 40 seconds, Ms Hanson thanked "Tony" for visiting her in her office and for sharing a cup of coffee.

"I think it is great too and I really appreciate you coming to my office and saying 'hello' and welcoming me to the Parliament," she said.
