Jan 21 (Reuters) - Two-time defending champions Japan brushed aside Myanmar 5-0 in their opening game at the
Women's Asian Cup in Pune on Friday while joint-favourites Australia thrashed Indonesia 18-0.
Chelsea striker Sam Kerr scored five times and Emily van Egmond hit four in Mumbai as Tony Gustavsson's side showed no mercy to an inexperienced Indonesia side marking the country's first qualification for the finals since 1989.
Kerr also became Australia's all-time leading scorer with her career 54th goal, breaking the previous record held by former men's international Tim Cahill.
Ellie Carpenter, Kyah Simon and Hayley Raso claimed braces while Caitlin Foord, Mary Fowler and Aivi Luik were also on the scoresheet as the 2018 runners-up made an uncompromising start to life in Group B.
The Matildas moved to the top of Group B on three points, with the Philippines in second spot on goal difference following their 1-0
victory over Thailand.
The Philippines, who had not beaten Thailand in 12 previous attempts, earned a late victory at Navi Mumbai's DY Patil Stadium after Thai keeper Waraporn Boonsing spilled forward Chandler McDaniel's shot in the 81st minute.
Earlier, West Ham United midfielder Yui Hasegawa struck twice for Japan as Futoshi Ikeda's side made light work of Myanmar in their opening Group C match.
Riko Ueki put the champions in front when she nodded in Hasegawa's 22nd minute cross but it took until the second minute of the second half before Japan doubled their advantage.
Hasegawa was released behind the Myanmar defence by Ueki's deft touch to slot home while Hikaru Naomoto's curling free kick gave the Japanese a third five minutes later.
Yui Narumiya hit the fourth from the edge of the Myanmar penalty area and Hasegawa capped a fine display in stoppage time when she clipped the ball over goalkeeper May Zin New.
Japan,
ICONWIN who beat Australia in the final in both 2014 and 2018, moved to the top of Group C on three points. South Korea defeated Vietnam 3-0 in the late evening contest and sit second on goal difference.
South Korea had the perfect start with captain Ji So-yun firing the opener from the edge of the box within four minutes and they soon had their lead doubled, thanks to an own goal from Vietnam defender Tran Thi Phuong Thao.
Ji completed her brace in the 81st minute, firing her penalty kick into the bottom left corner, after Vietnam defender Chuong Thi Kieu was penalised for a handball in the box.
