Expansion is seemingly always on the lips around League Central. Since the 1981 admission of the Canberra Raiders, the NRL has continuously looked to build out its competition.
Following the Green Machine, the Brisbane Broncos and Newcastle Knights joined in 1988, followed by the New Zealand Warriors and North Queensland Cowboys in 1995.
The Melbourne Storm joined the competition in 1999.
After a nine year break from expansion, the Gold Coast Titans entered the NRL in 2007.
