St George Illawarra maintained an unblemished start to the NRLW season, defeating Parramatta 10-0 in driving rain in Wollongong.

Earlier in Sunday's triple-header, Brisbane also stayed unbeaten following a 28-10 victory over Newcastle, while Gold Coast chalked up a history-making first win with a 26-16 defeat of the Sydney Roosters.

Despite the atrocious weather, the Dragons came out hot against the Eels, forcing a knock-on that allowed Rachael Pearson to cruise over for a try on 10 minutes.

Pearson converted her try to establish a 6-0 lead, which the Dragons carried through to half-time.

She added two penalty goals to her tally during the second half to score all the points in the match.

"It was pretty crazy … the girls dug so deep and I'm so proud of them all," Dragons captain Keeley Davis told Channel Nine.

"We worked really hard on (defence) … in years gone by we've been pretty poor in that area so it's been a massive emphasis for us."

Broncos tame Knights

The Broncos are undefeated after two rounds following their convincing victory over the Knights.

Millie Boyle and Tamika Upton were at their best for the three-time premiers, who touched down for five tries.

Boyle continued her impressive form, scoring the Broncos' opening try and posting 193 run metres for the match.

Upton was in on the act during the first half, combining with Shenae Ciesiolka in a slick one-two that allowed her to cruise through for a converted try and make the score 12-0.

Ciesiolka benefited from a perfect Upton assist to score the Broncos' third try early in the second half.

Debutant winger Hagiga Mosby then got her career off to a perfect start, bursting through to score in the corner after Amy Turner put her through.

Newcastle finally found some points when Maitua Feterika produced a hard-hitting run to find the line in the 56th minute.

The Knights produced a stunning try six minutes later as Jayme Fressard ran more than 70 metres to cut back the Broncos' advantage to 22-10.

But Turner sealed the win for the Broncos, running 40 metres and shrugging off multiple Knights defenders to score in the 66th minute.

Titans break through with first win

The Titans are celebrating their first NRLW victory after shutting down the Roosters.

In their first season in the competition, the Titans were dominant from the outset against their opponents.

Teenage debutant Jasmine Peters opened the scoring with a significant solo effort, fighting off Roosters' defenders with pure strength to find the line on four minutes.

A brilliant kick from Grace Griffin found Karina Brown in the corner for her first NRLW try, but Roosters winger Leianne Tufuga benefited from strong team play to pull the score back to 10-6 following an outstanding sideline conversion from Hannah Southwell.

The Titans immediately responded with a bulldozing try from former Rooster Tazmin Gray, allowing them to re-establish their 10-point advantage.

Another hard-hitting carry saw Brittany Breayley-Nati score under the post for a 22-6 lead to the Titans.

The Roosters would not go away, however, with prop Sarah Togatuki crashing over, before Olivia Kernick charged through the Titans' line to bring them within six points with three minutes to play.

But a clever solo run from Breayley-Nati sealed the Titans' win in the final minute, with her double earning her player-of-the-match honours.
