Australian Rhiannan Iffland has continued her dominance, winning the fourth stop of the 2022 Cliff Diving World Series in Norway.

Diving from a record-breaking 30m-long platform on the roof of the Oslo Opera House, Iffland edged Canada's Molly Carlson to take victory.

She picking up three nines from the judges for a beautifully executed third-round dive which Carlson was unable to match.

Another near-perfect fourth dive drew 9.5s from the panel for Iffland to seal her third win of the 2022 Red Bull series.

The victory meant reigning champion Iffland stretched her lead in the overall standings to 130 points.

"I'm riding this wave of confidence and really enjoying the diving," 30-year-old Iffland said.

Fellow Australian Xantheia Pennisi finished seventh.

In the men's event, Frenchman Gary Hunt took first place ahead of Italy's Alessandro De Rose and England's rising star Aidan Heslop.
