MATILDAS MIX OF YOUTH AND EXPERIENCE
Australia have two 17-year-olds in their squad; Ellie Carpenter and Princess Ibini, both of whom were born in 2000.
The overall roster is highly-experienced though with 11 of the 21 players boasting 48 or more internationals.
The Japanese team has been going through a major rebuilding phase after the retirement of many players who were central to the team's success in the first half of the decade, including legendary captain Homare Sawa.

The final games of the tournament are on Friday (AEST) when the Westfield Matildas meet Brazil and Japan play USA.
