Brisbane centre and former Redcliffe junior Kotoni Staggs has scored a length-of-the-field try to seal a stunning 18-12 win over the gallant Dolphins in front of a sold-out crowd in the first derby clash in the Queensland capital in 27 years.

Call it the 'Battle for Brisbane'. Call it the 'Battle of Brisbane'. It was a battle, and then some at Suncorp Stadium.
