Craig Kelly has been the member for Hughes since the 2010 federal election when he won as a Liberal candidate.
He resigned from the party to sit as an independent MP in February 2021, before joining Clive Palmer’s United Australia Party shortly after and announcing he would lead it at the next federal election, slated for 2022
He faced criticism over recent years for spreading misinformation on social media related to climate change and COVID-19.
In September, the Therapeutic Goods Administration accused Mr Kelly of breaching copyright and misleading the public about adverse reactions to COVID-19 vaccines.
Mr Kelly engaged in a text message campaign about vaccines, including a message with a link taking people to a database of adverse event notifications for vaccines.
Ahead of the federal poll, which must be held before 21 May, Ms Steele said she hoped that her standing as an independent MP will work in her favour.
“Hughes now is going to be the epicentre for Clive Palmer’s United Australia Party for the next election, given Craig Kelly is now that party’s leader,” she said.
“I am here saying, ‘there is a sensible, qualified person willing to stand up against the United Australia Party in the interests of the community of Hughes’.”
Ms Steele said she hoped to collect community donations and is in talks with Climate 200, a non-profit, non-partisan campaign group led by Simon Holmes à Court.
She said she sees her main competitor as whoever is selected as the Liberal Party candidate, acknowledging Craig Kelly has been elected as the MP for Hughes four times previously but only when he was running as the Liberal candidate.
“I won’t just sit here while the climate vandals leading the country and politicians bend even further to the extreme right,” she said in a campaign video.
Ms Steggall, a former Olympic athlete who won the seat of Warringah at the 2019 federal election as an independent MP, said Ms Steele’s candidacy was “great news” for the people of Hughes.
