Having won their opener 7-0, Australia again cruised through their match and now require a result to confirm their place at 2013's tournament
Australia are one draw from a place in the EAFF Women's East Asian Cup, moving to the brink of qualification after defeating Hong Kong 4-0 on Thursday.
The Matildas built on Tameka Butt's 33rd-minute header after half-time, with Kyah Simon, Kate Gill and Stephanie Catley rounding out a comfortable victory.
The margin could have been greater but for some desperate defending from Hong Kong, but - having trounced Chinese Taipei 7-0 in their qualification opener - the result still puts Australia on the cusp on making the tournament finals in July, 2013 in South Korea.
“It’s was probably one of those frustrating little games tonight,” Matildas coach Tom Sermanni said after the match.
“Hong Kong, to their credit, played with a lot of spirit, a lot of character.
“They basically parked eleven players twenty-five metres from their goal, blocked all and sundry that we through at them and defended as if their lives depended on it and did it very well.
“I think, from statistics, we had 83 crosses go into the penalty area, I don’t know how many corners and how many times we hit the woodwork.
“It was the kind of game where we hoped to have scored more goals, but at the same time, the players did what we asked them to do.
"We created enough chances and unfortunately on the night there was lots and lots of red coloured bodies around the place to block things.”
Australia face China on Saturday in their final group match, with Sermanni describing the match as a "huge game".
