The Commonwealth Bank Trophy, also referred to as the National Netball League, was the top level national Australian netball league between 1997 and 2007. The league was organized by Netball Australia. Its main sponsor was the Commonwealth Bank. Melbourne Phoenix were the competition's most successful team, winning five premierships. Sydney Swifts were the second most successful team, winning four premierships. Between them, Phoenix and Swifts played in every grand final, except in 1999 when Adelaide Thunderbirds won the second of their two premierships. In 2008, the Commonwealth Bank Trophy league was replaced by the ANZ Championship.
