Edmondson made it a hat-trick of omnium crowns as he reigned supreme against a star-studded field at Darebin International Sports Centre in Thornbury.

A dual world champion in the six-discipline event, Edmondson made it back-to-back Australian titles as he beat South Australian team-mates O'Shea and Miles Scotson.

”I’m pretty ecstatic,” Edmondson said after the race.

“To be able to beat someone like O’Shea - you don’t really have to say anything more than that - to be able to get one up on him is really special.

"I’m absolutely amazed."

Earlier this year, Edmondson teamed with O'Shea in the Bendigo International Madison track classic at the Tom Flood Sports Centre.

In the latest race for the omnium title, Edmonson lapped the field twice to earn a bonus 40 points in the final round points race.

The individual and team pursuit world champion finished the event on 242 points.

O'Shea, a world omnium champion and three-time winner of the Bendigo Advertiser Sports Star of the Year award finish on 198 points.

A gold medallist in the teams pursuit at the world titles and Glasgow Commonwealth Games, O'Shea is a finalist in the 50th Bendigo Bank Bendigo Advertiser-Prime 7 Sports Star of the Year award.

The focus for the track cycling stars is now on Saturday night's Australian Madison championship at Hisense Arena.

O'Shea will join forces with Jack Bobridge, while Edmondson and Miles Scotson team up in the madison.

A big night of racing at Hisense includes the women's madison in which Bendigo's Tayla Evans will team with Welsh ace Hayley Jones.

Another cyclist from Bendigo, Imogen Jelbart will contest the madison with Ashlee Ankudinoff.

A great carnival for Ankudinoff from Sydney began by winning Friday night's women's omnium.

Saturday's racing at Hisense includes the 117th Austral Wheelrace and the women's Austral.
