Folau made his debut for the Brisbane Broncos in round one of the 2009 season, scoring the team's first try in a 19–18 win over the North Queensland Cowboys. The following week, Folau again opened the scoring in the highly anticipated clash against his former club, Melbourne Storm, soaring above his former teammates to take a catch in what would be the first try in the Broncos 16–14 win – the club's first home win over the Storm since 2005. Folau continued his try-scoring feats averaging a try-a-game by Round 10. This was helped by a massive four-try haul against the Gold Coast Titans in May, equalling Brisbane Broncos Steve Renouf's record for the most tries in a single game for the Queensland club.
