One Nation Senator Pauline Hanson and former prime minister Tony Abbott have not had the best of relationships over the years.
Senator Hanson has held Mr Abbott responsible for her three-year jail sentence for electoral fraud, of which she served 11 weeks before the conviction was quashed.
She argued he was involved in bankrolling the court cases which led to her brief imprisonment in 2003.
"Pauline, it's good to catch up with you again after all these years," Mr Abbott said in the video of their meeting posted to Senator Hanson's Facebook page.
