Teams
In 2023, the line-up of teams changed for the first time in 8 years with the addition of the Western Clydesdales. The North Queensland Cowboys changed their affiliation agreement, with the Cowboys sending all NRL contracted players not selected in their weekly squad to just the Townsville Blackhawks.

On 15 June, the Brisbane Broncos annulled their affiliation agreement with the Norths Devils after the Devils announcement that they had signed a four-year affiliation agreement with the Dolphins from 1 November 2023 ahead of the 2024 season. In response to the news, the Brisbane Broncos would remove their players from the Devils for the remainder of the season.
