World Rugby’s eligibility rules have opened the door for a number of high-profile internationals to represent a different nation at the 2027 Rugby World Cup.

Most would qualify through the three-year stand-down period introduced in 2022, while others are yet to make their Test debut despite previous involvement in international squads.
From established stars to intriguing outsiders, here are 10 players who could be wearing different colours in Australia.
10 Billy Vunipola (Tonga)
Vunipola was born in Australia to Tongan parents before later relocating to the UK. He is now eligible to change national allegiance under World Rugby regulations after earning the most recent of his 75 England caps in 2023.
Last year, reports connected him with a potential move to Tonga, while his Australian birthplace also leaves Australia as an option.
He has recently spoken against playing for Tonga, saying “To think about going back and potentially blocking a young Tongan kid who wants to give his family the same opportunity that I’ve had, I think would be pretty greedy.”
Although his stance appears clear, he still has time to switch should he reconsider.
9 Jack Willis (Ireland)
Willis qualifies for Ireland through his grandfather and would become eligible in late 2026 under World Rugby birthright laws, which allow a change of Test allegiance after three years away from international rugby.
Ireland’s centrally contracted players all represent one of the four provinces and only in very rare cases, such as fly half Johnny Sexton’s brief spell with Racing, have players been selected while based overseas.
The 29 year old back row forward won the latest of his 14 England caps with a single appearance at the 2023 Rugby World Cup. He now plays for Toulouse in the Top 14, which makes him ineligible for England under RFU rules.
8 Ma’a Nonu (Samoa)
The iconic centre last played Test rugby 11 years ago when he helped the All Blacks win the 2015 World Cup and continues his career in France with Toulon.
At 44 years of age, Nonu is still impressing in the Top 14 with his power, experience and skill, prompting speculation that an improbable return to international rugby may not be impossible.
Under current World Rugby regulations, players may change nations after a stand down period if they qualify through birthright.
With Samoan heritage, Nonu would therefore be eligible to represent Samoa, who are eager to strengthen their squad after a challenging recent qualification campaign.
7 Hoskins Sotutu (England or Fiji)
Sotutu last represented the All Blacks in November 2022 and will become eligible to switch to either England or Fiji in 2026. He qualifies for England through his mother and Fiji through his father.
In December 2025, Sotutu is set to leave New Zealand and move to England to join Newcastle Red Bulls in PREM Rugby on a three year deal starting in the 2026 to 27 season, which would make him eligible under RFU rules.
6 Val Rapava Ruskin (Georgia)
While not strictly a switch, as he has not represented another country, Rapava Ruskin could feature for Georgia at a World Cup. As a prop, however, he would be entering a position where they already have significant depth.
In June 2019, he was one of four uncapped players named in England’s provisional World Cup training squad.
He was again included in England’s training group in the summer of 2023 ahead of the summer fixtures and the 2023 Rugby World Cup.
Born in Tbilisi, he left Georgia at the age of two and was raised in England.
