Darryl "Brax" Braxton is a fictional character from the Australian soap opera Home and Away, played by Steve Peacocke. He made his first screen appearance during the episode broadcast on 16 February 2011. The character was created and introduced along with his two brothers; Heath and Casey. The trio were nicknamed The River Boys and were inspired by the real life Bra Boys group. When Peacocke learnt about the role of Brax, he initially thought he would not suit the part as he is from the country. However, after learning more about the character, Peacocke successfully auditioned for the role. Peacocke's departure was announced on 1 February 2015 and Brax made a temporary exit on 10 June 2015, before returning on 9 December. He made his final appearance on 7 June 2016.

Casey Braxton is a fictional character from the Australian Channel Seven soap opera Home and Away, played by Lincoln Younes. Casey made his first on-screen appearance on 17 February 2011. Younes was about to go travelling when he auditioned for the role of Casey. He changed his plans upon winning the role. In late 2010 the Seven Network began airing trailers for a new trio of characters known as "The River Boys". The trio consist of Casey and his older half-brothers Darryl and Heath Braxton. The River Boys arrive in Summer Bay from neighbouring town Mangrove River. Casey is characterised as being a "modern day Rebel Without a Cause"; who is intelligent and unsure about what he wants out of life. Younes has described him as the "epitome of teenage angst". The River Boys cause trouble in Summer Bay and producers were inspired by Koby Abberton's Bra Boys in the creation process. Casey is portrayed as wanting to distance himself from their bad reputation; but his anger issues often mar his attempts.
