India's cricket team clinched a thrilling Test-series win against Australia in Brisbane by becoming the first country to defeat the hosts at the Gabba since 1988.
Australia had been undefeated in 31 previous Test matches at the venue – winning 24 – since losing to the West Indies there more than 32 years ago.
Here, the PA news agency takes a look at a selection of other lengthy sporting unbeaten runs.
Jahangir Khan (squash)
Khan lays claim to one of the most impressive winning streaks ever, having gone undefeated in all tournaments from 1981 to 1986. The Pakistani was crowned World Open champion aged 17 and won his next 555 matches before losing in the World Open final five years later to New Zealand's Ross Norman.
Edwin Moses (athletics)
American 400-metre hurdler Moses' 122-race winning streak is the longest in track history. Moses was untouchable for almost a decade and set new world records on four occasions. After finishing second to West Germany's Harald Schmid in August 1977, he did not lose again until beaten by fellow American Danny Harris in June 1987.
Arsenal (football)
The Gunners set an English top-flight record of 49 league games unbeaten in 2003-04. They became the first side in the modern era to go an entire season undefeated (26 wins, 12 draws). Their unbeaten run was finally ended in 2-0 defeat to Manchester United at Old Trafford in their 10th league game the following term.
West Indies (cricket)
The West Indies embarked on a 15-year unbeaten run in 1980 which saw them undefeated in 29 Test series. From 1980 to 1995 they won 20 series and drew nine. During that run they went unbeaten in 27 matches, winning 17 and drawing 10 and set a joint record of seven straight Test series wins from 1982-1986.
New Zealand (rugby union)
The All Blacks have not lost in 44 Test matches at Eden Park, Auckland, stretching back to a 20-23 defeat to France in 1994. Since then, only two sides have managed to avoid being beaten, South Africa (18-18) in 1994 and the British & Irish Lions (15-15) in 2017. Between 2009 and 2017, the All Blacks won a record 47 Tests at all venues on home soil.
Martina Navratilova (tennis)
Navratilova won a record 74 consecutive singles matches in 1984. After losing to Hana Mandlikova in the Virginia Slims finals in January that year, the Czech-born American went unbeaten until losing to Helena Sukova in the Australian Open semi-finals. Defeat to Sukova, a teenager from Czechoslovakia, dashed Navratilova's hopes of a record seventh consecutive grand slam title.
