The 2005–06 Australian cricket season took place from October 2005 to March 2006.
The 2005–06 Australian cricket season began on 2005-10-05 with the first official ICC Super Series match, and the home season lasted until 2006-03-27 when the Pura Cup final concluded. The national team are, however, playing away matches until 2006-04-28. Australia played six home Tests during this season – three against West Indies and three against South Africa – and also hosted the three-team VB Series, between Australia, South Africa and Sri Lanka. The team also toured New Zealand for One Day Internationals in December, played five ODIs and three Tests in South Africa in February and March, and visited Bangladesh for the first time in April. Also, the season included a new domestic competition, for the first time in 36 seasons – a Twenty20 tournament called the Twenty20 Big Bash was held in January 2006, with two groups of three teams and the group winners proceeding to the final.
A limited-overs cricket tournament has been a feature of Australian cricket since the 1969–70 season, branded as the Matador BBQs One-Day Cup for the 2015–16 season. Initially a knockout cup, the competition now features a single round-robin followed by a finals series, with matches limited to 50 overs per side. The tournament is contested between teams representing the six states of Australia, who also compete in the first-class Sheffield Shield. Three other teams have also played in the tournament for short periods of time: New Zealand's national team competed in several early tournaments, a team representing Australian Capital Territory participated for a brief period in the late 1990s, and Cricket Australia XI took part as the seventh team for three seasons starting with 2015-16.
England was the first country to introduce a domestic one-day limited-overs competition with its Gillette Cup in 1963. Australia was the next country to do so when this competition was established in 1969–70. It has been held every summer since, under a wide variety of names and formats. It is a List A cricket competition. It was the first List A competition to feature numbers on player's shirts when they were introduced for the 1995-96 season.
The Ing Cup is an international Go tournament, with a large cash prize of over US$400,000. It was begun, and is named after, Ing Chang-ki.
In the 7th Ing Cup (2012/13), Fan Tingyu (b. 1996) beat Park Junghwan (b. 1993) [3-1] and became the youngest Ing Cup winner in history. In the semifinal, Fan defeated Xie He, and Park defeated Lee Chang-ho.
The Ing Cup is sponsored by Ing, Yomiuri Shimbun, the Nihon-Kiin, and Kansai-Kiin, and held every 4 years (and thus often nicknamed Go Olympics). The competition has its own rules and an 8 point komi. The time allotment is 3.5 hours for each player, while players are available to buy an extra 35 minutes for an additional 2 point komi a maximum of three times. The first rounds are knockouts, while the semi-finals and finals are a best-of-3 and best-of-5 respectively.
