ON Friday, the Matildas made history with a first ever win over world champions the USA.

On Monday, they've done it again, this time with a big 4-2 win over Asian champions Japan to go to the top of the table in the Tournament of Nations.

Led by a brilliant first-half Sam Kerr hat-trick, Emily Van Egmond then scored a penalty on the hour mark to recover from a horror start after Japan took the lead six minutes into the match.

But that only served to kick the Aussies into gear, who themselves had a good chance just 60 seconds into the match.

Up stepped Kerr, who hit a lethal double in five minutes.

Her first came after Elise Kellond-Knight played Hayley Raso in behind, with the right winger flying beyond Japan's back four to square the ball to Kerr for a tap in on 11 minutes.

Then Kerr did it herself in the 16th minute, winning the ball back high up the field to race in behind one-on-one with the goalkeeper to score.

And just as Japan probed for an equaliser on the stroke of half-time, Kerr scored a break away solo goal to seal her hat-trick.

Japan then scored a late consolation goal in the second minute of stoppage time, but it was Kerr who stole the show.

You can watch the Matildas v Brazil in the Tournament of Nations from 9.10am AEST Friday on Fox Sports 503.
