St George Illawarra's Rachael Pearson has nailed a golden-point field goal to secure a 19-18 win over Brisbane in Melbourne and book her team a spot in the finals.
It was the first time a NRLW match had been decided via golden point and also the first occasion the Dragons had ever beaten the Broncos.
In Saturday's earlier match in Melbourne, Gold Coast recorded its maiden win of the season with an 18-16 defeat of Parramatta.
The Dragons looked headed for a straight-forward victory on Saturday until Brisbane skipper Ali Brigginshaw crossed with just over a minute remaining.
Tarryn Aiken added the extras to lock the match up.
The Red V looked on the back foot early in golden point when Tara McGrath-West lost the ball in a tackle, but a successful captain's challenge showed it had been stripped by Brisbane's Amber Hall.
The Dragons then worked the ball down field with Pearson kicking her team to a win from more than 20 metres out.
The halfback was also able to convert each of her team's three tries, scored by Kezie Apps, Quincy Dodd and Elsie Albert.
The win moved St George Illawarra onto six points, level with the unbeaten Sydney Roosters and Newcastle, who square off on Sunday.
It leaves the Broncos with just one win from four matches and in danger of missing the semifinals with one round to play, with Gold Coast joining them after its earlier win over Parramatta.
Titans claim first win of NRLW season
Forty-year-old prop Steph Hancock has gone to the top of the NRLW's try-scoring charts to help keep Gold Coast's season alive with the win over Parramatta.
In a crucial match for both teams, the Titans raced out to an 18-4 lead at half-time before holding on to claim victory.
The result leaves Parramatta winless after four rounds, with their season effectively over unless a string of results go in their favour over the next week.
The Titans will live to fight another day, able to qualify for a second-straight finals series if they beat the Sydney Roosters at Central Coast Stadium next Sunday.
They were also forced to ice the match without halfback Lauren Brown, who was taken from the field with 12 minutes to play after being hit late by Kennedy Cherrington.
And they did it off the back of their forwards.
One of the greats of the women's game, veteran Hancock scored the Titans' first when she claimed her fourth try of the season from close distance.
The front rower is now top of the charts for this season, while she remains equal-second on the all-time lists with eight tries in her last eight matches.
Fellow prop Shannon Mato also bagged a first-half try as part of a mammoth effort up front, before George Hale and Kimiora Breayley-Nati put Jessika Elliston over for the 14-point half-time lead.
But Parramatta was not willing to go away.
Simima Taufa put the Eels back in the match when she busted through a hole and went 30 metres to score before Rima Butler made it a two-point match with seven minutes to play.
But ultimately crucial errors out of their own end would come back to burn the Eels, as they sunk to defeat by a narrow margin for the third straight week to cruel their season.
