A State of Origin match will be played in Perth for the first time in 2019.
The second game of the series will shift to the city's new stadium, marking a move by the NRL to play only one match in Sydney and Queensland.
The shift is expected to be confirmed on Friday by NRL chief executive Todd Greenberg, but comes after a 2018 match will also be taken to Melbourne as part of a three-year rotation cycle.
The match could be played in front of up to 60,000 people, with the new Burswood Stadium scheduled to be opened in 2018.
It will also come after the city hosts its first rugby league Test match later this year, with Australia and New Zealand set to do battle at nib Stadium in October.
West Australian premier Colin Barnett has confirmed his government paid an undisclosed amount to win the rights to the Origin match.
