Canberra winger Jordan Rapana and sister Tazmin Gray are set to become the first brother-sister duo to play on Grand Final Day.

Gray’s Brisbane Broncos will face St George Illawarra in a curtain raiser at ANZ Stadium with Rapana will run out of for his first NRL grand final as Canberra battle the Sydney Roosters.

Rapana and Gray are just two of ten siblings.

“We talk a fair bit about footy,” Gray told AAP.

“It’s obviously real good to have a brother like that. Growing up I always followed everything he did.

“He’s a massive role model and playing in a grand final is the closest thing I will be able to do to run out on the field and play before him.”
