Six months after winning election to the Murray Bridge council, a Labor candidate is ready to have another crack at the federal seat of Barker.
Mat O'Brien has been endorsed to run against Liberal MP Tony Pasin after an unsuccessful tilt in 2016, and another at the 2018 state election.
The Murray Bridge resident said he would campaign on standing up for the River Murray and South Australia's fair share of water, a stronger focus on the regions, and a greater commitment to local schools, hospitals and roads.
Mr O'Brien, the vice president of SA Country Labor, also said he planned to host community meetings across the electorate in the lead-up to the May 18 election "to ensure residents in Barker are listened to and don't have their votes taken for granted".
He said Labor was united, ready to govern, and had a plan for better hospitals and schools instead of "tax loopholes for the top end of town".
He criticised Mr Pasin for his apparent involvement in the failed leadership push by Home Affairs Minister Peter Dutton, saying the MP's time would have been better spent focusing on the people of Barker.
"I want Barker to have the best possible representation in Canberra," he said.
"If given the opportunity, this will be my priority."
The president of SA Country Labor, Limestone Coast-based state MP Clare Scriven, said Mr O'Brien understood the issues facing local people, such as the importance of the Overland train service.
"Mat O'Brien lives and works with his young family in Barker ... and, if elected, will do a fantastic job in representing residents' views in Canberra," she said.
Seven candidates have now nominated in Barker so far, including Mr Pasin, the Centre Alliance's Kelly Gladigau, the National Party's Miles Hannemann, the Greens' Rosa Hillam, United Australia's Rupert Bacher and the Animal Justice Party's Karen Eckermann.
