He had to fight his way into his first Olympic team, now Mitchell Iles is primed for a second crack after earning a quota spot for Australia in the men's trap on the final day of the Oceania shooting championships.
Iles, still only 20, and Sergei Evglevski won gold in the men's trap and 25m rapid fire pistol respectively on Friday.
Both earned quota spots for their efforts, meaning Australia will be able to fill 15 positions for next year's shooting program in Tokyo.
Iles opened with two perfect rounds of five shots in high winds, with Athens bronze medallist Adam Vella a shock early casualty in the final despite entering as the highest-ranked shooter.
Iles and Vella were the men's trap pairing at Rio's Games but only after Iles was forced into a Court of Arbitration battle arguing against his controversial omission.
Michael Diamond, a gold medallist in Atlanta and Sydney, was eventually withdrawn from the team because of his gun and drink driving charges.
Iles held his nerve on Friday, shooting 43 of 50 targets to defeat team-mate Daniel Di Pietro.
"I'm absolutely wrapped to win and get a quota position. That was the goal but the conditions were very tough," he said.
"The wind was strong and gusty and the light was in and out."
A comfortable winner ahead of Thomas Ashmore, Evglevski said he would enjoy a short holiday in Bali before nailing an Olympic berth with another strong showing at the final Olympic selection trials next year ahead of March's team announcement.
New Zealand's Natalie Rooney (37 targets) beat Australian pair Lisa Smith (33) and Breanna Collins (26) in the women's trap.
Australian shooters Laetisha Scanlan and Penny Smith had already claimed Tokyo Games quota positions in the event.
