The first challenger to Tony Pasin's run as federal Member for Barker has emerged: Kelly Gladigau.
The nurse and previous state candidate has been pre-selected as the candidate for the Centre Alliance, formerly the Nick Xenophon Team.
She said she was thrilled and privileged to be running for a party which gave South Australians a voice and put people first.
“Since running as a candidate in the recent state election I have continued to advocate for people and business throughout the electorate," she said.
"I now look forward to running a strong campiagn to represent the Barker electorate on a federal level."
She is also currently running for election to the Mid Murray Council, but said she did not expect one to affect the other unless she won the federal poll, likely to be held next year.
She will kick off her federal campaigning at Murray Bridge Community Club tomorrow night, where athletes hoping to form a local triathlon club will gather at 6.30pm.
“I’m looking forward to a strong and positive campaign, and to listening to people about what they want,” she said.
The Liberal Party has already confirmed its continued support for Mr Pasin as Barker's federal MP.
Mr Pasin defeated a Xenophon candidate by winning 46.6 per cent of first-preference votes, and a majority on preferences, at the 2016 election.
Ms Gladigau won 22.7 per cent of first-preference votes in this year's state election.
