Australia coach Tony Gustavsson said taking on weaker teams in the run-up to co-hosting next year's Women's World Cup would only give the country a false sense of security.
The Matildas lost a second game in four days against Canada at Sydney Football Stadium on Tuesday, heaping more pressure on Gustavsson little more 10 months out from the tournament.
The losses to the seventh-ranked Canadians followed a 7-0 defeat to eighth-ranked Spain in June and left the Matildas without a win in their last four matches.
