Dylan Alcott will bid to retain his status as the king of Melbourne Park when the Australian Open Wheelchair Tennis Championships begin tomorrow.

The Australian has won the quads singles title at his home Grand Slam for five straight years and seems untouchable in front of his own fans.

Alcott, who has won Paralmypic gold medals in both wheelchair tennis and wheelchair basketball, is the top seed with the four quads players contesting a round-robin before the final.

He will open tomorrow against compatriot Heath Davidson, while American David Wagner, beaten by Alcott in four of the last five finals, will take on Britain's Andy Lapthorne.

Reigning US Open champion Lapthorne goes into the opening Grand Slam of the year as the new world number one.

Alcott will also be searching for a third quads doubles title in a row after winning the last two with Davidson.

They will play Lapthorne and Wagner in the final.

In the women's singles, Dutch player Diede de Groot is hoping for a third consecutive Australian Open title.

The top seed begins in the quarter-finals against China's Zhenzhen Zhu.

Japan's second seed Yui Kamiji will be hopeful of a second Australian Open crown after winning last week's warm-up event, the Melbourne Wheelchair Tennis Open.

She has been drawn with Britain's Jordanne Whiley in the last eight.

There is an all-Dutch quarter-final between Aniek van Koot and Marjolein Buis while Germany's Sabine Ellerbrock will take on South Africa's Kgothatso Montjane.

De Groot and Van Koot are the top seeds in the women's doubles and will defend their title.

They have been handed a semi-final clash to start against Buis and Zhu.

Singles rivals Kamiji and Whiley will team-up to play the second seeds, Ellerbrock and Montjane, in the other last four clash.

Argentina's second seed Gustavo Fernandez is the defending champion in the men's singles and begins in the quarter-finals against Britain's former winner Gordon Reid.

Japan's 2018 champion Shingo Kunieda heads the seeds and plays Frenchman Nicolas Peifer.

Joachim Gerard of Belgium won the warm-up event and has been drawn against Australian wildcard Ben Weekes.

Britain's Alfie Hewett will play France's Stephane Houdet in the remaining quarter-final.

Gerard and Stefan Olsson of Sweden won the men's doubles last year but will not defend their title.

The Belgian is instead teaming with Weekes for a semi-final against France's top seeds Peifer and Houdet.

Second seeds Reid and Hewitt will play Fernandez and Kunieda.
