This is confirmed. Pretty huge news as it is the first current Australian RU International player to switch codes for 2 decades:
Rugby World Cup star Mark Nawaqanitawase has become the first incumbent Wallaby to defect to rugby league in two decades after signing with the Roosters on a two-year deal from 2025.
Nawaqanitawase informed Rugby Australia, NSW Rugby and his teammates on Wednesday night he had agreed to terms with the Bondi club and will switch in the NRL after his rugby contract ends in 2024.
