Citlalli Reyes made the difference for Mexico on her record-breaking 13th tournament appearance to see El Tri into the knockouts.

The first chance of the game fella Mexico's way, as Mia Urbano bundled her way into the area and sent a left-footed curler towards goal which crashed off the crossbar.

Australia wouldn't escape next-time, though, as Reyes finished off a flowing move with a low drive into the bottom corner in the 35th minute.

Natalia Perez came closest to doubling the North American sie's lead in the second half when her edge-of-the-box drive also rebounded off the woodwork.

One, however, proved to be enough for the Mexicans, who will now tackle Nigeria in the last 16 on Thursday.
