The pair claimed the title on a historic night in Frankfurt, Germany.

Simon Whitlock, nicknamed The Wizard, and Damon Heta, nicknamed The Heat, defeated Welsh duo Gerwyn Price and Jonny Clayton 3-1 in Sunday’s decider to become only the fifth country to lift the trophy.

Ten years on from suffering World Cup heartbreak in an extraordinary 2012 finale against England, losing 4-3 in a sudden-death leg alongside Paul Nicholson, Whitlock fulfilled his darting destiny alongside Australian No.1 Heta to scoop the £70,000 ($A123,120) top prize at the Eissporthalle.

Australia, the fifth seeds, had already dumped out five-time semi-finalists Belgium and top seeds England on Finals Day.

“It is life-changing. I have dreamt about this moment my entire life and I’ve finally got there,” an emotional Whitlock, one of four World Cup ever-presents, said.

“It feels amazing. I had a great partner. Damon has been amazing. He’s a great friend, and he’s the best player on the planet right now. He is going to be the next world champion.”

Heta gave Australia the early impetus in the final with a stunning singles whitewash win over Price, before 53-year-old Whitlock battled past Clayton 4-2.

The 2012 runners-up had the momentum and opened up a two-leg buffer in the pairs contest, but Price and Clayton produced a stirring fightback to prolong the drama.

Whitlock missed a dart at double 18 for the title, and Clayton capitalised for the Welsh via double eight to clinch the match and reduce the arrears to 2-1.

Clayton then had the chance to set up a grandstand finale between Whitlock and Price, but 34-year-old Heta produced a nerveless display in the biggest game of his life to fend off the former Premier League champion and spark jubilant celebrations from the Australian duo.

“Simon dragged me through the beginning,” Heta said.

“I’m stoked for Simon and stoked for Australia with all the support we’ve had back home.

“Everything we are sacrificing being here and we’ve got the title in the bag. It’s an amazing feeling.”
