Sydney full-back "Leaping" Leo Barry, who took that mark in the dying moments of the AFL grand final, turned his attention to rugby in a bid to help the Australian Sevens side master the art of catching the high ball.

"It's basically more a case of teaching them how to mark. With their kick-offs, they are finding they have probably a lack of judging the ball and being able to take a mark above their head," Barry said at Lakeside Oval, near the SCG.

"If they can improve that skill it will go a long way."

But 28-year-old Barry denied he was planning to switch codes with the Melbourne Commonwealth Games looming next March.

"I think Mat Rogers is pretty safe at the moment. I'm quite happy kicking our little red ball around," he said.

Barry, who hails from the NSW Riverina town of Deniliquin, admits his rugby knowledge is not brilliant.

Australian coach Glen Ella, however, was more than happy to take a punt with his new guest coach.

"From this session, we need to be more confident attacking the ball in the air. That's why Leo's here," Ella said.

"With the re-starts, a team can hold the ball for nearly the whole half if they are very good at what we are doing here today.

"We are learning to be aggressive and confident in taking the high ball."
