Quade Cooper

Cooper said he wants to swap codes and give the 13-man game "a fair crack" with Williams, a good friend of his, at the Toronto Wolfpack before the pair retire.

"I want to play with Sonny before we both retire. But I wouldn't mind playing NRL either, just for one season or even just come and do some training with the lads to see what it is like," Cooper said on the Ice Project podcast.

"If it doesn't happen, it doesn't happen. I am happy with what I have been able to achieve, but if the opportunity arose I would love to do it."

"If he actually cared about Aus rugby he would have done it a while ago," Cooper wrote on Twitter.

The 31-year-old first-five hasn't played for the Wallabies since 2017.

He was included in the preliminary squad six months out from the World Cup in Japan, but didn't make the final 31-man party.

A Wallabies regular until the Rugby Championship this year, the five-eighth will skipper the invitational team at Sydney's Allianz Stadium on October 28.

Jones, a former Wallabies coach, tweeted the announcement on Wednesday and interviewed the 70-test veteran on his 2GB radio show.

Cooper has been playing for Brisbane City in the NRC this season while the Wallabies have played New Zealand, South Africa and Argentina.

The 29-year-old said he would be out to entertain rugby fans with a focus on attack.

Kerevi made his return to the Wallabies fold this week after missing the June series with an ankle injury, but it was without his long-time Queensland teammate, who was a high-profile absentee from Michael Cheika’s Rugby Championship training squad.

Cooper’s omission was an that surprised players and fans alike, coming after a challenging year at the Reds.

The 70-Test Wallabies flyhalf has taken the chance to head on an overseas holiday while the Wallabies are in camp and Kerevi said Cooper was staying positive despite being overlooked.

Hunt, who started at inside centre in all three of Australia's June tests, was a notable absentee at training on Monday in Newcastle. 

The 30-year-old will spend about two months on the sidelines, putting him in doubt for at least the Wallabies' first four matches of the Rugby Championship. 

Although Hunt has played mostly in the midfield, the Wallabies are low on playmakers and many assumed Cooper would return despite being overlooked last week in Cheika's extended squad. 

It wasn’t quite Quade 2.0 against the Springboks, rather an enhanced prototype of the mercurial flyhalf, with a dose of maturity mixed in.

In a good mindset after an injury-free season to this point, something that has been a rarity for Cooper in the past, the returned Wallabies playmaker said he had managed to add thin

“When I went away before that all I knew was the Reds,” he said.

“Not knowing anything else, not knowing any style of play, but also for me, while I was overseas understanding how I thought about my rugby, I was able to add things to my game.

The agreement takes the New Zealand-born playmaker through until the end of the 2019 rugby World Cup in Japan.

The 28 year old re-joined the Wallabies ahead of the Rugby Championship and started at first-five in last weekend's second Bledisloe Cup test defeat to the All Blacks in Wellington.

"For me, playing at the highest level for the Wallabies against the best teams in the world, week in, week out is the ultimate, and it will always be the pinnacle of our sport," Cooper said.

The former Wallaby, who is attached to French club Toulon, arrived in Sydney on Wednesday, three days before the tournament, but misses the chance to make his national sevens debut with no place found for him in the 12-man squad.

"Due to circumstances which were beyond Quade's control and our control, he just couldn't get enough work in this week with the team," new Australian Sevens head coach Andy Friend said.

The Wallabies and the third-ranked All Blacks are scheduled to meet at 9pm on Saturday in the nightcap of the opening day's play. 

Williams was picked in New Zealand's squad on Monday on the back of a fluctuating performance in the third leg of the World Rugby Sevens Series in Wellington over the weekend. 

"I'm really pleased with how I went this weekend to tell you the truth," Williams said afterwards. 

"The pleasing thing is being able to be in an environment where, even though I'm a rookie, everyone wants to help you out." 

Williams has been included in the New Zealand squad to play in Wellington this weekend, a strong pointer he will also feature in the inaugural Sydney 7s world series leg on February 6-7 at Allianz Stadium.

The All Blacks' World Cup champion has taken a season off Super Rugby to seek selection for the Rio Olympics, and his new coach, Sir Gordon Tietjens, says Williams is ahead of schedule in his transition to the seven-a-side game.
