The Jillaroos have underlined their women’s rugby league dominance with a 34-10 annihilation of New Zealand in the World Cup final.

The hosts did the damage with six first-half tries on Sunday at Suncorp Stadium, winger Jaime Chapman with a brilliant first-half hat-trick to cap a historic tournament.

Victory was the Jillaroos’ fourth-straight Cup triumph, following a 54-4 win in the final four years ago and coming after New Zealand had won the first three tournaments between 2000-08.

Chapman carried two players more than 10 metres to score her first, before flying into the corner for another and then busting through four tacklers for a sensational 70-metre solo effort.

That saw her equal the record for tries scored in a World Cup campaign - for men or women - at 13.

It seemed inevitable that she would go clear in the second half.

But both teams struggled in the Brisbane humidity, with the Kiwi Ferns’ try in the finals seconds the only points scored in an error-riddled stanza.
