Defending champions Yui Kamiji, Dylan Alcott and Shingo Kunieda were all victorious as the wheelchair tennis competition began at the Australian Open.
Kunieda, who is seeking an 11th men's wheelchair singles title in Melbourne, dropped only one game in his opening match.
The Japanese star beat Australian Ben Weekes 6-1, 6-0 and will play Britain's Alfie Hewett in the final.
Another Briton - Gordon Reid - was the only player to knock out a seed, as he came from behind to defeat Argentina's 2017 and 2019 champion Gustavo Fernández.
Reid won 5-7, 6-4, 6-4 and will play Belgian Joachim Gérard for a place in the final.
In the women's singles, Kamiji was dominant in dispatching Chile's Macarena Cabrillana 6-0, 6-1.
Kgothatso Montjane is up next for Kamiji, with the South African saying before the tournament that reaching a first-ever Grand Slam final was her goal.
Top seed Diede de Groot won an all-Dutch affair between two former champions, edging past Aniek Van Koot 6-0, 3-6, 6-4.
Momoko Ohtani of Japan awaits in the semi-finals.
In the quad singles, Australia's Alcott beat compatriot and doubles partner Heath Davidson 6-0, 7-5 in the quarter-finals.
This is the first year that the quad draw has been expanded to eight players.
The Netherlands' Niels Vink beat Nicholas Taylor of the United States and will play Alcott in the semi-finals, while Andy Lapthorne of Britain and Sam Schröder - the Dutch US Open champion - will meet in the other semi-final.
The tournament continues tomorrow.
