New Zealand's complete domination of sevens rugby proves that parachuting in part-time stars is not the recipe for success it might seem, according to Australian Commonwealth Games captain Ed Jenkins.

Popular opinion says Australia should inject Israel Folau and other Wallabies stars into sevens for the sport's Olympics debut in Rio in 2016.

However, Jenkins insists such an assumption is an insult to the unique physical and technical demands of his fast-paced sport.

New Zealand have never been defeated in Commonwealth Games competition, dating back to Kuala Lumpur in 1998.

While Australia's sevens set-up has long resembled a transit lounge, the Kiwis have mostly avoided the temptation to bring across All Blacks or use the sevens format as a mere pit-stop for up-and-coming 15s stars.

The ARU this year followed New Zealand's lead and moved to a central contract system, and Jenkins says if Australia can keep their core group of young players together ahead of Rio, consistent results will follow.

"New Zealand have had the same group of key, core players for five or six years which has really helped them," Jenkins said.

"I think they (ARU) did use it as a stepping stone ... but I think that's completely changed now.

"The ARU knows it's a separate entity.

"You can't really use it for that tool otherwise you're just not going to compete against those big nations."

Jenkins wants the ARU to fight to keep up-and-coming rugby stars like Cam Clark and Tom Cusack on the books so Super Rugby clubs can't poach them before Rio.

Jenkins said Folau might be a once-in-a-generation talent - but insists he still couldn't come in cold to a major sevens tournament and excel.

"It's funny when you hear that a Wallaby will just jump in and find it easy," he said.

"Izzy would have the skills and all that, but I think he'd have to come across early just to get that conditioning level.

"We bring people in all the time who are great athletes and great football players. But they do one week and pull up with torn hammies and back problems. It takes time to adapt.

"We're not a shortened form of the 15s game - it's a different game."

On the field, Australia geared up for the Commonwealth Games with a 20-15 defeat of Scotland in a low-key practice game on Tuesday.
