A disappointing second half has seen the Gold Coast SUNS go down to a finals-bound Brisbane outfit on Saturday afternoon at the Gabba.

The SUNS opened up a handy lead at half-time before Brisbane launched a counter-attack which saw them run out 17.18 (120) to 10.11 (71) winners.

The Suns brought a pressure-laden first half similar to the style of football that has delivered recent wins against Richmond and GWS along with a competitive loss to the Bulldogs last round, but it was a different story after the long break.

With a September second chance on the line, the Lions lifted to produce a powerful third quarter, turning a 27-point half-time deficit into a six-point lead at the final change before running away to the convincing result on the back of an unanswered 11-goal streak.

Touk Miller was Gold Coast's best, while Jeremy Sharp continued his upward curve in game number seven, surpassing the 30 disposals he grabbed against the Bulldogs and slotting his second career goal.

Midfielder Brayden Fiorini also battled all day and finished with a match-high 41 disposals to go with eight marks and four tackles.

Key forward Ben King moved into second in the Coleman Medal count after booting three goals, all in the first half.
