Wallaroos

The Wallaroos performance was full of errors, while the Japanese success was based on some outstanding defence.

Both sides scored two tries with Australia having the chance to steal the result late in the game but normally reliable goal kicker Lori Cramer missed a penalty attempt in the 77th minute.

The result will improve the world ranking for the Japanese who are currently ranked 12.

The Japanese also beat Fiji 28-14 earlier in the series.

It will be the first time the Manusina have played the Wallaroos since 2009 and their first Test since beating Tonga in November to advance to the final Rugby World Cup repechage.

Head coach Ramsey Tomokino said it was the first time he could remember the Samoa women being a part of a Test series and not just a one-off match.

"We're just grateful for any opportunity we can get and...for our players opportunities that you cry out for, that we've been seeking and wanting to have," he said.
