The 2006–07 A-League was the 30th season of top-flight soccer in Australia, and the second season of the A-League since its establishment the previous season. Football Federation Australia hoped to build on the success of the first season and on the interest generated by the Socceroos competing in the 2006 FIFA World Cup. Fox Sports had signed a A$120 million deal over 7 years for the exclusive broadcast rights of the A-League, AFC Champions League, and national team matches.

Since 2011, the club has been owned by Welnix, a consortium of seven Wellington businessmen.
