Former One Nation leader Pauline Hanson says she is planning to run in this year's federal election.

Ms Hanson says she believe there's no "representation" of Australian life and people in parliament.

"I'm going to put my hand up. I'm going to apply for the job and hopefully the people think that I'm the best person for that job to represent them," Ms Hanson told the Seven Network.

Ms Hanson said the rising costs of electricity and the 457 visa system are the issues which concern her most.

"Water is a huge issue in this country and that needs to be investigated, along with the costs of electricity. I don't think the government is doing enough to understand that people are hurting," she said.

Ms Hanson, who served in federal parliament from 1996 to 1998, said her political comeback was "not about revenge".

"I went to jail, it took me over two years to get over, and it's that determination that I feel can keep me going. Why give up for something I feel that is right," Ms Hanson said.

Ms Hanson narrowly missed out on a spot in the NSW upper house in 2011.

She said she had lost on preferences before because politicians didn't want "someone like me in there who's going to bring them to accountability".
