Australian rugby captain Stirling Mortlock is adamant the door to Wallabies selection should remain shut to overseas-based players like the code's latest prize recruit Mark Gasnier.

Along with Australia's most successful league convert Lote Tuqiri, blockbusting centre Mortlock expected the former St George Illawarra NRL star to prosper in the 15-a-side code.

Kangaroos centre Gasnier made an instant impact on his debut for French rugby club Stade Francais last Friday.

Playing on the wing for the side coached by former Waratahs mentor Ewen McKenzie, he scored a try in a 32-25 win over Bourgoin.

His two-year contract effectively rules him out of Wallabies selection during that period, as current Australian Rugby Union (ARU) policy is to choose only locally based players.

Asked by AAP if he would like to se the ARU relax their stance on players domiciled offshore, Mortlock said not at this stage.

"My thoughts on that is that we've got to do everything in our power to make sure that Australian rugby is really strong and it starts with developing the players domestically at club level and provincial level and then trying to get as strong a Wallaby side as possible.

To do that I think, the mechanism that seems to be the most positive is having players chosen that are playing in Australia."

Mortlock and Tuqiri both expected Gasnier to do well in rugby provided he was willing to put in the work on learning the nuances of the highly technical code.

"He is a quality player and I've got no doubts if he keeps on working, he can go well," Mortlock said.

Tuqiri, who has accumulated 66 Test caps since moving over from rugby league, believed Gasnier had the attributes needed to succeed.

"He's a freak athlete, he's a freak player he can beat a tackle, he can swerve, he's got a great step, he's got speed, they are all ingredients to be a good rugby player as well as a good league player," Tuqiri said.

"He's just got to get used to how you train and body height and positioning and positioning on the field and that will only take him a month or a couple to get used to it.

"He's done well with Ewen being coach, having an English speaking coach which is probably really good and smart for him."

The normally reserved Mortlock said he felt a huge amount of excitement and positivity about the Wallabies coming six-match spring tour, which starts with a Bledisloe Cup clash against New Zealand in Hong Kong and ends with a match against the Barbarians at Wembley Stadium, with Tests in between against Italy, France, England and Wales.

"We would have liked to have got a result in our last match (the Tri-Nations decider against New Zealand), it wasn't to be, but I think nonetheless that's probably instilled a little bit of resolve amongst this group to hopefully have a really positive tour," Mortlock said.

"We've got four uncapped players coming into the group a few of the guys that weren't in the 30 for the last Test match come back in, it's very exciting.

"A lot of young guys are going extremely well so far this season and it's going to be a great test for them and for us as a group."
