Roberta Williams has been chosen as the Australian People's Party candidate for Mr Shorten's seat of Maribyrnong in Melbourne, but her status as an undischarged bankrupt could rule her out of the race.

The Federal Court declared Ms Williams bankrupt over a $300,000 tax debt last year.

She also spent six months in jail in 2004 for her involvement in a drug ring that supplied 8,000 ecstasy pills to undercover police.

Ms Williams said she deserved a chance to take a tilt at federal politics.

"So many wrongs have been done to me and other people that I believe need to be fixed and the Government at the moment doesn't seem to know how to do that," she told reporters outside her Melbourne home.

"I have haters, I have likers, I have people who love me, we all do in society. I believe that everyone deserves a chance at giving anything a go and if you've got the capabilities to do so, do it."

Ms Williams would not comment on her bankruptcy status.

Mr Shorten said he was focussed on Labor's policies, not potential candidates.

"Every Australian is allowed to nominate for Parliament and I don't blame anyone wanting to represent the north-western suburbs of Melbourne," he said.

Williams to campaign on homelessness, troubled youth

The People's Party was registered in March in a bid to restore the vision of government as "of the people, by the people, for the people".

On its website, Ms Williams is described as a "charitable person" who plans to campaign on health, homelessness and troubled youth.

"Roberta has a great understanding of the needs of the homeless, troubled youth, people with disabilities, people with mental health issues and those experiencing financial difficulties," the site reads.

The party's policies include a "prosperity tax", making education free, cutting health system red tape, and asset protection so that governments cannot privatise schools, roads, power, ports and parks.

Under section 44 of the Australian constitution, a person is blocked from becoming a federal MP if they are an undischarged bankrupt.

A party spokesman said one of Ms Williams' daughters would run as a candidate if she was ineligible to stand.

Roberta Williams was married to underworld figure and murderer Carl Williams, who was bashed to death by another inmate in Barwon Prison in 2010.
