Written off before the Tokyo Games had begun, the Hockeyroos, headlined by Gerringong's Grace Stewart, have achieved a feat no other Australian side has achieved in Olympics history.
The women have won four-straight matches to start a campaign for the first time, a feat even more remarkable given Australia has claimed three gold medals at past Games.
The latest win was a tight 1-nil victory over tram-Tasman rivals New Zealand that went down to the wire.
A 34th minute Emily Chalker goal proved the difference in a match that had few scoring opportunities.
Australia will now play Argentina in their final group match, a win to secure the Hockeyroos first place in the group.
Even a loss will likely see the side finish on top, such is their superior for and against.
The first half was an even affair, both sides experiencing periods of ascendancy.
There were times that were tight, the two teams getting into the grind and attempting to wear their opponents out.
Then there were periods that were open, free-flowing and highlighted by end-to-end action.
One trend persisted throughout, however. Both defences were up to the task.
Each time a team looked to be in a position to generate an opportunity, they were shut down.
Australia managed just two penalty corners in the opening half, the first well defended while the second was poorly executed and did not result in a shot.
The set-piece continues to be an area of concern for coach Katrina Powell, the side now two from sixteen during the Games.
New Zealand had zero shots throughout the opening 30 minutes, each attacking raid quickly snuffed out by the Hockeyroos.
Australia broke through six minutes into the second half and they remained on top through much of the third quarter.
They were not, however, able to drive home their advantage and the Black Sticks Women continued to push for an equaliser.
The fourth quarter played out in similar fashion, both sides desperate for a goal.
For Australia it was a chance to kick clear, for New Zealand the all-important equaliser.
The Kiwis made the bold call to pull their goalkeeper with more than four minutes remaining to create an extra field player in their efforts to level the scores.
The move proved futile, the Hockeyroos defence holding firm to secure a 1-nil victory.
