Britain's Alfie Hewett and Gordon Reid, men's doubles silver medallists at Rio 2016 and Tokyo 2020, were also victorious at Melbourne Park.

Top seeds de Groot and van Koot have now won the Australian Open women's doubles event for the last three years, recording a straight sets victory against Japan's Tokyo 2020 doubles bronze medallist Yui Kamiji and China's Zhu Zhenzhen.

De Groot and van Koot won the first set 6-3 and the second 6-2 to triumph in one hour and 14 minutes, the longest of the day's wheelchair doubles finals.

Paralympic champions Schröder and Vink took just 58 minutes to overcome South Africa's Donald Ramphadi and Brazil's Ymanitu Silva 6-1, 6-3.

They are now the holders of all four Grand Slams in quad doubles, and avenged a defeat to Britain's Andy Lapthorne and United States' David Wagner in last year's final at the Australian Open.

Second seeds Hewett and Reid won the wheelchair men's doubles for the fourth consecutive year, denying The Netherlands a clean sweep of the medals with a 6-1, 6-2 victory over Maikel Scheffers and Ruben Spaargaren in one hour and three minutes.

They have now won 11 of the last 13 doubles Grand Slams, bouncing back from defeats in last year's Wimbledon and US Open finals.

The wheelchair singles finals are due to be held tomorrow between Hewett and Japan's Tokito Oda in the men's, de Groot against Kamiji in the women's and Vink and Schröder in the quad.

The women's and quad singles finals are between the top two seeds, while Hewett against Tokito would be first against third.
