The Australia National Netball Team, commonly known as the Australian Netball Diamonds, represent Australia in international netball tests and competitions. The team was formed in 1938 and played in the first international game of netball, against New Zealand. In 2008 the team adopted the nickname "Diamonds" in line with other Australian sporting teams, including the national women's basketball team, the Opals.
Australia have traditionally been regarded as the most successful netball team in international netball: they have won ten of the thirteen World Netball Championships, in addition to being the current world champions and ranked first in the INF World Rankings. The Diamonds compete annually in a home-and-away test series, the Constellation Cup, with perennial rivals New Zealand. Regular test matches are also held with other major netball countries, including England and Jamaica. To date, Australia have won ten World Championships and three Commonwealth Games events.
The Diamonds are administered by Netball Australia, the national governing body for netball in the country. Players are usually selected from Australian ANZ Championship franchises. The team are presently captained by Queensland Firebirds defender Laura Geitz. Lisa Alexander was appointed head coach in August 2011, taking over from Norma Plummer.
Historically, the Australian team has had an edge over perennial rivals New Zealand, as posting 54 victories, as opposed to New Zealand's 36 out of the 90 tests they have played (as at October 2008), including two matches ending in a draw.
On 8 September 2008, Netball Australia launched officially named the national team the Australian Netball Diamonds. Continuing the trend set by the Australian women's basketball team, the Opals, Netball Australia made the announcement and described it as a milestone event in the sport's 80-year history in Australia.
Australia has competed in all six World Netball Series. The first series saw Australia's side all Diamond test players. Since the second series the fastnet/fast5 Australian team has contained both youthful and experienced players normally those just missing or not ready for Diamonds selection yet. Australia's Fast5 team is called the Fast5 Flyers.
