The Matildas have failed to capitalise on multiple gilt-edged scoring opportunities in a 1-0 loss to Canada in a pulsating international soccer friendly at Brisbane's Suncorp Stadium.
Olympic champions Canada took a 1-0 lead into half-time thanks to a superb strike by Adriana Leon and three cracking saves by goalkeeper Kailen Sheridan when Matildas skipper Sam Kerr appeared certain to score.
The first half was an open affair with 11 shots on goal. The Matildas had seven of them.
After the break it was end-to-end with Australia allowing Canada far too much latitude while in possession, an area of their game they need to improve before next year's FIFA Women's World Cup kicks off in Australia and New Zealand .
Kerr laid a neat flick on for substitute Cortnee Vine to fire just wide in the 83rd minute as Australia pressed for the equaliser. Kerr missed out again in injury time when Sheridan again tipped a header over the bar.
Matildas coach Tony Gustavsson said defender Charlotte Grant did a good job on star Canadian forward Nichelle Prince overall but admitted that when the game opened up the Matildas "got exposed on the counter a bit too easy".
"We weren't intense enough in the first half. I think we were much more physical in the second half," he said.
Gustavsson said the Matildas "never say die" attitude was in evidence at the end as Kerr went in search of the equaliser.
"Sam is a world-class goal scorer and on other days she scores three and everyone is really happy and she's happy," he said.
"It was just one of those days. We need to work on our final pass to set her up for success."
The Matildas were well served by 19-year-old midfielder Mary Fowler who was busy throughout and involved in much of the good work done by the side.
Central midfielder Katrina Gorry was also outstanding, with her passes opening up opportunities for the forward line.
A header by Kerr in the fourth minute was superbly denied by a diving Sheridan after a neat cross from the left by Emily Van Egmond.
Canada opened the scoring in the 11th minute when Leon, who plays on the wing for Manchester United, was given too much space just outside the box and speared a rocket finish into the top right corner.
An advancing Sheridan denied Kerr again after a slick through-ball from Gorry. Gorry, who took a year off in 2021 to have a baby girl Harper, proved a constant threat.
The Matildas lost defender Alanna Kennedy to a leg injury before half-time and she was replaced by Aivi Luik.
With 320 days to go until the World Cup kicks off, Gustavsson has signalled that consistency and continuity in the team lineup will be key as he tapers the side toward being at their best when the crunch games are on.
Gustavsson was not able to start this campaign with his best team, with seven starting players from the Tokyo Olympics semi-final side that lost 1-0 to Sweden unavailable.
Two of those - forward Caitlin Foord and defender Steph Catley - told Channel 10 before kick-off they were hopeful of being available for the second clash with Canada in Sydney on Tuesday.
