One Nation leader Pauline Hanson has taken calls about family law, domestic violence and support for people with disabilities during a marathon phone-in on New Year's Eve.

Senator Hanson said on her Facebook page that she was taking calls to reduce loneliness as part of a Lonely Hearts 2020 initiative.

The senator and advisor James Ashby started fielding calls, live on Facebook, at 6pm.

The phone-in is expected to continue until midnight, Queensland time.

Speaking about family law issues, Senator Hanson said there were calls from men and women who were not able to have access to their children.

"My heart goes out to parents who don't see their children," she said.

In a discussion with Mr Ashby about local government, Senator Hanson said it was "disgusting" what some chief executive officers got paid.

Senator Hanson said the idea of the phone-in came after reports revealed one in four Australians feel lonely, The Courier-Mail reported.

"Let's have a fun night together and let's reduce the loneliness tonight across Australia," Senator Hanson says on her Facebook page.
