Rebekha Sharkie

House of Representatives Electoral record At the 2016 federal election, Sharkie defeated Briggs with 55 percent of the two-candidate preferred vote.

On 9 May 2018, Sharkie announced her resignation from the House of Representatives following the High Court of Australia ruling that Senator Katy Gallagher was ineligible to contest the 2016 election as a consequence of the 2017–18 Australian parliamentary eligibility crisis. Like Gallagher, Sharkie had failed to complete renunciation of her British citizenship before nomination in the 2016 federal election. She contested the 2018 Mayo by-election on 28 July, and was returned to parliament with a swing in her favour.

Sharkie successfully defended her Mayo seat in the May 2019 federal election winning her seat with a two candidate preferred vote of 55.14%, up 2.22% on the previous election. She was re-elected in the 2022 Australian federal election with the support of the Teal independents, and re-elected to serve a fourth term in the 2025 Australian federal election. Prior to the election she hinted at her support for a Liberal–National Coalition in a hung parliament.

Party affiliation Sharkie was the only Nick Xenophon Team (NXT) candidate elected to the House of Representatives at the 2016 election, joining Xenophon and Skye Kakoschke-Moore who were elected to the Senate.

NXT changed its name to the Centre Alliance in April 2018, after Xenophon ceased his active involvement with the party. Sharkie was the only candidate for Centre Alliance at the 2022 and 2025 elections. In a 2025 interview, she described it as a "party of one" and stated its continued existence was due to difficulties with electoral laws allowing the transfer of funds from a registered party to an independent.

Political views and advocacy Sharkie approached finance minister Mathias Cormann in 2019 about funding a research centre in the region that includes the complex ecosystems of the Coorong, Lower Lakes, and Murray Mouth. The Coorong, Lower Lakes and Murray Mouth (CLLMM) Research Centre in Goolwa, run by the Goyder Institute for Water Research, was officially opened by Sharkie in early February 2024.

In 2026, Sharkie announced that she would introduce a private member's bill to outlaw burning of the national flag, as well as the Aboriginal flag and the Torres Strait Islander flag. Her bill would have provided for offenders to be jailed for up to two years.

Personal life , Rebekha is married to Nathan Sharkie. They live in Birdwood, South Australia. She has three children from a previous marriage, which ended around 2008.
