Holly McNamara has scored her first international goal but new Matildas coach Joe Montemurro was left with plenty to ponder after his side scratched out an unconvincing 3-0 win over Slovenia in Perth.
Emily Gielnik's third-minute strike in Thursday night's match at HBF Park got the 15th-ranked Matildas off to a flyer, but it wasn't until McNamara scored in the 86th minute that the win was safe.
Hayley Raso added the icing on the cake in the 87th minute when she waltzed through the midfield untouched before unleashing a strike from outside the box.
Although the 3-0 scoreline looked good on paper, the performance was far from slick in front of a crowd of just 8,678.
The under-strength Matildas were error-prone throughout the night, especially in defence where they attempted to play their way out of trouble at every chance.
Montemurro's possession-based game plan was always going to have teething problems, but the sheer amount of errors will be a huge concern.
Things started brightly when Gielnik stayed persistent in a goalmouth scrap to score the opener.
But the Matildas' determination to retain possession at all costs led to numerous sloppy turnovers, many of which should have been punished.
Time and again, the Matildas opted to go backwards instead of finding the gaps further ahead -- leading to problems whenever Slovenia were able to pick off the pass.
One such turnover let Spela Kolbl off the leash in the 15th minute, with her floating cross glancing off the crossbar.
The Matildas' best opportunities in the first half generally came when defender Ellie Carpenter found some space to charge forward, with her pace and physicality proving hard to stop.
The Matildas' worst defensive error of the night arrived in the 52nd minute when Clare Hunt was unaware an opponent was bearing down on her as she attempted a short pass.
She got stripped of the ball but was left breathing a huge sigh of relief when Slovenia striker Zara Kramzar fired straight at Matildas keeper Teagan Micah from close range.
It was Alanna Kennedy's turn to commit a horror mistake 10 minutes later when her clumsy attempt to control the bouncing ball while running back to defend resulted in a costly deflection.
Slovenian substitute Nina Kajzba pounced on the mistake, with her strike forcing Micah to make a fine diving save.
McNamara, who has endured three knee reconstructions during her career, was a threat throughout the match.
The 22-year-old, playing her 10th international, finally received her reward when she put away a header at the far post following a sublime cross from Raso.
McNamara's teammates mobbed her as she celebrated her first Matildas goal.
A minute later, Raso went on a run and curled in a precision strike from the edge of the box.
The Matildas went into the international window missing a host of their best players.
Sam Kerr (knee), Mary Fowler (knee) and Tameka Yallop (leg) were all out through injury, while Steph Catley, Caitlin Foord, Katrina Gorry and Cortnee Vine are all on personal leave.
The Matildas were dealt another blow just days out from Thursday's match when Clare Wheeler left the camp for personal reasons.
Australia face Slovenia again in Perth on Sunday, before taking on Panama in Bunbury on July 5 and in Perth on July 8.
