Broncos lock in NRLW finals spot, Roosters to host semi

Brisbane will return to the NRLW finals after putting the cleaners through St George Illawarra to win 46-12 and wrap up a top-four berth.

The pacesetters in the women's game for the first four seasons, the Broncos missed the finals for the first time last year when they finished second-last.

A similar struggle looked on the cards this season when Brisbane dropped their first two games before winning six of their next seven to reach the finals.

Their win at Kogarah on Saturday night was the most convincing of the lot.

Julia Robinson scored a hat-trick in the victory, with her first two tries coming when Brisbane put it through hands before the winger's third came via a 95-metre intercept.

Mele Hufanga crossed for a double in the win, with the rampaging centre taking her tally of tries for the year to 10.

Fullback Hayley Maddick put Hufanga over for her first when she charged into a hole, before the powerful centre barged through five defenders for her second after the break.

Fellow centre Shenae Ceisiolka also claimed a brace, against a Dragons side that has fallen from semi-finalists to as low as seventh spot.

The night was marred by an injury to Dragons five-eighth Tyla Nathan-Wong, who left the field on a stretcher and in a neck brace after reeling out of a tackle.

Brisbane will now face either the Sydney Roosters or minor-premiers Newcastle in next week's sudden-death semi-final.

The result also means Gold Coast or Canberra will fill the last finals spot, with the Raiders needing to beat the Titans by 12 or more points on Sunday to leapfrog them into the top four.

Earlier, Isabelle Kelly helped the Roosters lock in their home semi-final as she scored a try and set up two others in a 40-16 win over North Queensland.

Missing several of their biggest names and playing strength-and-conditioning coach Millicent Scutt as a bench hooker, the Roosters powered home against the ninth-placed Cowboys.

The Roosters expect to have Keeley Davis (hamstring) and Mille Boyle (shoulder) both back for the finals, while Jess Sergis will not return from a hand injury.

But there were more concerns on Saturday night, but winger Tyler Bentley suffering a leg injury and five-eighth Tarryn Aiken on report for a high tackle.

Bench forward Pani Hopoate is also at risk of a ban, after being sin-binned for a hip-drop tackle that left Jasmine Peters with a moon boot on her right foot.
