The 23-year-old claimed the WA1500 Revolver and WA48 Revolver world titles before defending his club teams pistol title with his father Dean - and missing out on the revolver title by just one point - before winning the world teams with Chris Banfield in pistols.

"It's pretty surreal," Brus said, looking at the haul on his lounge room table.

"No Australian has ever won the main match in the 1500 and no-one's ever won two (individual titles), and dad and I backed up and did the club teams and came second by one.

"I definitely wasn't expecting it."

While all the wins had sentimental value attached to them, Brus said being the first Australian to claim the WA1500 pistol title meant the most.

He claimed that title, and the four-inch pistol title, on the first day of competition, but couldn't let loose and celebrate with four events to come.

"It was a great big high on Friday and you found out your on the podium four times, five times, but can't celebrate because you've got teams the next day," he said.

"To shoot club teams in the morning and be told, yep, you're world champion with your coach and your dad again and second by one point and [have to] settle back down again."

"Then you shoot revolver, find out you're third, think you're on the podium but it's not quite what you want and then you get Australia winning at the international world teams ... it's unreal."

This is Brus' fourth time shooting for his country in the international world teams, which pits the two best shooters in the country against each other, and each year he'd come second.

Until last weekend.

"It's really, really nice to not be the bridesmaid any more," Brus said, laughing.

Achieving the success he had was made sweeter not just by being on home soil, but for the chance to compete in front of grandparents, uncles, aunts and family members who had rarely - and in some cases never - seen him shoot competitively was special.

The win was also embraced by his "second family" - Emus Rugby Club - who he won a second-grade premiership with last month, and he gave part of the credit for his win to playing rugby in the lead-up.

"I've never felt better heading into a competition than this year," he said.
