One Nation senator Peter Georgiou arrived in Esperance on April 23, ahead of a looming federal election.
Mr Georgiou was last in Esperance in June 2017, when his party had four senators in the federal parliament.
Along with One Nation leader Pauline Hanson, he is now one of only two party MPs remaining in the senate.
Mr Georgiou said the party had "had a few mishaps", but he was confident about his prospects ahead of the May 18 vote.
"We're quite confident that, come the next election, we'll have four or maybe five senators on the cross-bench," he said.
"I'm feeling fairly confident that [I will] hold One Nation's senate spot in WA."
One Nation is still battling scandal after an undercover investigation revealed key One Nation figures looked at sourcing donations from the United States and discussed watering down Australian gun laws.
Mr Georgiou would not comment on how the scandal would affect his chances of re-election, but confirmed he did not want to see Australian gun laws weakened.
"I'd like to see our gun laws left the way they are," he said.
"I think we've probably got the best gun laws in the world. I don't want to see our gun laws go down the same path as America's."
The senator said the biggest issue for Esperance voters when he was last here was the jetty, and was pleased the project had received $4 million from the federal Building Better Regions Fund.
"It's a good outcome for the community here. They all want this jetty to be built again," he said.
"I don't know what state the jetty is in, whether it needs replacing or restoring.
"I would assume the path they [the Shire of Esperance] go down is the one that is financially viable."
Mr Georgiou said fighting for an increased share of the GST for WA and the provision of MRI machines across regional communities were achievements during his time in the senate.
