A jam-packed Barker ballot paper will give voters plenty of choice for their lower house representative.
The electorate of Barker has expanded beyond the Barossa Valley to include more Light townships including Kapunda and Freeling.
On top of incumbent Liberal MP Tony Pasin, candidates from the the Greens, the Animal Justice Party, United Australia Party, The Nationals and Centre Alliance have all put their hands up to compete for your votes.
Get to know a little bit about each candidates and what they are promising to do for you:
Liberal - Tony Pasin
Tony Pasin has been the federal MP for Barker since he was elected in 2013 and re-elected in 2016.
Tony operated his own legal practice in the South East, representing local farmers, residents and businesses.
As a young father and family man, Tony says he knows first-hand the real challenges faced by families in Barker, as they confront rising cost of living pressures and access to quality healthcare, jobs and education.
"The Morrison Government understands that having strong regions creates a strong Australia and that is why we are continuing our record investment in supporting regional communities like the ones in Barker," Mr Pasin said.
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".
Centre Alliance - Kelly Gladigau
Representing Centre Alliance, formerly led by Nick Xenophon, Kelly Gladigau is hoping to "bring about the real change that our community and our state desperately needs."
Kelly Gladigau is a fourth-generation farmer's wife, mother of five children, registered nurse, volunteer and committee and board member of local community organisations in the mid Murray region.
"Like many of my fellow constituents, I am proud of the rich history and opportunities that a regional area such as Barker offers us, our families and our communities."
"However, I have also become disenchanted by the same old 'it's one party or the other' option."
United Australia Party - Rupert Bacher
Formerly known as the Palmer United Party and led by Queensland billionaire Clive Palmer- the United Australia Party has endorsed Rupert Bacher as their Barker candidate.
Rupert Bacher is a retired welder and timber worker from Mount Gambier.
He immigrated to Australia in 1963, with only 24 pounds in his pocket, and says he has joined the United Australia Party to give back to the country he loves.
Animal Justice - Karen Eckermann
Murray Bridge Councillor Karen Eckermann will represent the Animal Justice Party at the election, she announced at the council's meeting last week.
"My aim is to raise the profile of the Animal Justice Party and the values it promotes: kindness, equality, rationality and non-violence," she said.
"We can all be quite confident I won't be elected, but I am thrilled at the opportunity to do something important for an issue I care so much about."
Cr Eckermann had previously campaigned against live exports, corella culling and greyhound racing, among other causes, as both a councillor and a founding member of Murraylands Animal Welfare Watch.
She described living in a distict where animal agriculture was so prevalent as "a big challenge".
Her candidacy would not affect her commitment to serving the ratepayers of Murray Bridge, she said.
The Greens - Rosa Hillam
Describing herself as a "community-minded artist", Rosa Hillam has worked as a Healthy Rivers Ambassador and River Fellow to help save our precious Murray Darling Basin.
"I'm also passionate about improving rural services, such as domestic violence and substance abuse treatment facilities, and I have been an advocate for quality regional aged care and mental health services." Ms Hillam said.
"I hope to raise the quality of life for regional communities and protect the country's land and water."
She launched her campaign in January.
The Nationals - Miles Hannemann
Kieth businessman, Tatiare Districtor Councillor, and former SES and ambulance service member Miles Hannemann has been endorsed as the Nationals Barker candidate.
"I have 4 boys and I want to create opportunities for them in our communities, here in Barker," Mr Hannemann said.
"We need to provide secure local jobs and bring people back to our regions so we can secure our way of life for future generations."
"We have a strong story to tell - lower cost of living, affordable housing, cheaper industrial land, fantastic amenities and ideal locations to raise families."
"I believe in regional development and I want to make sure that we are not just talking about economic development but the social and cultural development that needs to occur alongside."
