“The whole team watched Norway against Canada," said Garriock. "Norway is a very physical team. I guess the main point of difference between the sides is speed.

“[Lisa] De Vanna and Walshy [Sarah Walsh] are going to kill them with their speed upfront.”

Certainly both strikers looked lively in the 4-1 win over Ghana on Wednesday night. It was Australia's first ever win at a World Cup.

De Vanna in particular shone in a 45 minute cameo that would've had alarm bells ringing in the Norwegian camp.

De Vanna's two goals in the opening group game were particularly impressive and her speed caused Ghana endless bother.

“She's a gun player," said Garriock of De Vanna. “Her speed is phenomenal and she is good tactically. She's done the business and is going to be hard to stop.”

Walsh too was a lively presence upfront although her finishing disappointed her.

“I wasn't very happy with my finishing,” she said today. “And Norway will be more structured so there'll be no way I'll be left alone on the halfway line like I was against Ghana.”

Overnight, Norway defeated Canada 2-1 in the Matildas' group. Garriock wasn't buying into whether the final group match against Canada would be the decider in the group.

“Every game is important. We want to win all three games. No-one is thinking too far ahead,” added Garriock of the clash with the world ranked four nation on Saturday.

The only injury concern coming out of the Ghana match is Jo Peters who is doubtful for the crunch Norway match.

Matildas' legendary striker Julie Murray told au.fourfourtwo.com that the campaign had got off to a "promising" start.

"We have a fast, mobile frontline. De Vanna is perfect in that role as an impact player who can take advantage of the latter stages of a game," she said.

"We should be proud but there's a long way to go. Against Norway, you're not going to get many chances, so we'll have to take them if we get them. But things are looking promising."
