Mavrik Geyer will join Perth's Bears for their 2027 debut, continuing his father Mark's Western Australian connection.
Mark Geyer, a Western Reds marquee signing from 1995 to 1997, expects the Bears to reach the finals in their first season.
"This Bears side can win half their games next season. They could shock rugby league and play finals footy, of course they can." Mark Geyer told News Corp.
The Reds won 11 of 22 games in 1995, and Geyer believes Perth's home fixtures could help the new side avoid last place.
The Bears are expected to blend young talent with experienced NRL players, including Gehamat Shibasaki, Tyran Wishart, Nick Meaney, Toby Sexton and Siosifa Talakai.
Perth has made Matt Burton a lengthy offer for 2028, while hoping to secure an earlier move.
The full squad is expected to relocate by the end of November for pre-season training.
