A nurse with the Navy Reserve in Brisbane, Adams shot with surgical precision, hitting 59 from 60 targets in the final to defeat fellow Australian Joshua Bell (52 targets).

Experienced New Zealander Paul Wilson (39 targets) captured the bronze.

Adams was thrilled with his performance, which equalled the Oceania record and clinched a 2020 Tokyo Olympic Games quota position.

"I've been working my butt off in recent months and all the hard work paid off today," said Adams.

"The quota place was the icing on the cake.

"I will now take a couple of weeks off and get ready for the final Olympic selection championships beginning in February."

West Australian Bailey Groves also snared a Tokyo Olympic Games quota position with the final shot in what was a thrilling 10m Men's Air Pistol final.

Groves (234.4 points) edged Australian teammate Scott Anderson (234.3) by 0.1 point, with four-time Olympian Daniel Repacholi (213.2) winning the bronze medal.

Anderson went into the final round with a 0.7 lead but could only manage 19.0 with his final two shots, while Groves shot a gold medal-winning 19.8.

"I'm still shaking in my boots," said a relieved Groves.

"0.7 was a good lead for Scott and I knew it was going down to the last shot. There was a lot of pressure and the stakes were high.

"When I first looked at the scores, I thought we had tied and that we were going into a shoot-off, but then I looked at the decimal point and saw that I had won.

New Zealand's Chloe Tipple won the first Kiwi gold medal of the championship, dominating the Women's Skeet.
