Rugby Australia boss Raelene Castle will launch a review into their overseas player eligibility rules, in a move which could see the Wallabies hang on to some of their top talent.
Known as the "Giteau Law" in honour of former Wallabies back Matt Giteau, the rule, which was introduced beforethe 2015 Rugby World Cup, allows Australian players to still represent the Wallabies while playing overseas, as long as they have played 60 tests and have played professionally in Australia for at least seven years.
However, with key Wallabies such as Samu Kerevi (23 tests), Rory Arnold (19 tests) and Adam Coleman (29 tests) all having signed overseas contracts after the 2019 World Cup, there is a chance that Rugby Australia could significantly change the law to strengthen their national side.
Castle said that she would discuss changes with Rugby Australia's director of rugby Scott Johnson and high performance manger Ben Whittaker.
"The Giteau rule has worked really well for us and if you think about the players we couldn't select for the World Cup, there is probably only three or four you would look at and say they would have had a big crack at making the Wallabies for the World Cup."
Castle, who added that South Africa and New Zealand are both reviewing their rules surrounding overseas-based players, said it would "irresponsible for us not to review it".
The rule has a loophole where players such as Nic White and Matt Toomua are allowed to be picked in the World Cup squad despite not meeting criteria, as the pair have both signed to return to Super Rugby in 2020.
Rugby Australia investigated making a similar deal with lock Will Skelton, but he re-signed with Saracens, instead aiming to return to Australia in 2021.
"He basically had to give up the last year of his Saracens contract, and sign with Rugby Australia and we would have had some flexibility like we did with Nic White and Matt Toomua, they could finish their seasons and come back and play the back few games of Super Rugby, that would have been within the bounds of the Giteau law," Castle said.
"But he was looking to not come back until the following year and that wasn't acceptable to us."
Castle stressed that even if they changed the law, there would still be a rule in place to keep top players in Australia and playing Super Rugby.
"We need our good players playing Super Rugby, so we need to make sure we look at it from that perspective.
"Don't give any open doors for opportunities for players to think 'well I'm going to disappear off and not play Super Rugby and then I'm a dead cert to be selected for the World Cup.
