The Westfield Matildas have been forced to settle for a 0-0 draw with Portugal in their second Algarve Cup match on Saturday morning (AEDT).
Denied an early penalty, Australia battled hard against the host nation but were unable to replicate the fluidity of their 4-3 win over Norway.
Alen Stajcic made four changes to that team but retained Clare Polkinghorne for the experienced defender's 100th international cap.
Despite the draw, the Westfield Matildas remain first in Group A ahead of their clash with China PR on Tuesday morning (6:00am AEDT).
STORY OF THE GAME
- CONTROVERSY: Australia were denied what appeared to be a clear early penalty when Chloe Logarzo was tripped, only for the referee adjudged the foul as being outside the area.
- CLASS DEFENDING: Polkinghorne anticipated a threatening moment midway through the half to snuff out a shooting opportunity for Jessica Silva.
- SAVE! Lydia Williams next came to Australia's rescue, smothering a one-on-one with Diana Silva.
- CHANCE: Lisa De Vanna looked set to break the deadlock shortly after the hour, but she was unable to trap Sam Kerr's cross.
- INJURY: Stajcic's injury problems grew with Emily Condon forced off with an ankle problem shortly after coming on for her international debut.
- SAVE! Williams again did well to tip over a deflected Vanessa Marques effort.
- CHANCE: Kerr was bundled over on the edge of the area in the dying moments, but Alanna Kennedy's misdirected free-kick meant the deadlock remained intact.
