Westfield Matildas attacker Chloe Logarzo admits she was taken aback by Korea Republic's cautious tactics in Sunday morning's 0-0 draw in Amman.
Australia were afforded almost complete control in their first match of the 2018 AFC Women's Asian Cup as the Taeguk Nangja were content to hang on for a point.
Lydia Williams did not face a shot until the 93rd minute, with Logarzo conceding it was tricky to break down such a committed rearguard.
"It was a tough game. We knew it was going to be hard," the Sydney FC star told FFA TV.
"I definitely think they parked the bus a lot more than we expected.
"But they did a great job and all praise to them.
"We didn't lose, so it's a tournament where we just need to win the rest of our games and that will get us through to the World Cup."
Logarzo's start at King Abdullah II Stadium marked her debut appearance in the AFC Women's Asian Cup.
The 23-year-old was joined in the XI by a strong core featuring the likes of Williams, Clare Polkinghorne and Lisa De Vanna.
"It was nice. It would have been better with the win," she said.
"I was a little bit nervous but it was nice with the rest of the girls around [and especially] all the experienced players."
