It's neck and neck as the NRL's Broncos and the A-League's Roar prepare for a spectacular Brisbane cross-code sporting popularity contest.

The Broncos kick off a monster sporting weekend in South East Queensland on Friday night with their home season-opener against North Queensland at Suncorp Stadium.

The action switches to the Gold Coast on Saturday night when the Titans host Wayne Bennett's 2010 NRL premiers and World Club Champions St George Illawarra in front of an expected capacity house at Skilled Park.

And the footballing spectacular continues on Sunday afternoon when the all-conquering Roar meet Central Coast in the A-League grand final back at Suncorp Stadium.

The question Queenslanders are asking is whether the Broncos or the Roar will pull the bigger crowd to the Brisbane venue.

"It's too close to call," said a Suncorp Stadium spokesman, adding that both matches appeared to be heading for 45,000-plus crowds.

Broncos chief executive Paul White was far from concerned by the competition from the A-League revelations, believing both clubs could profit from it.

"Queenslanders traditionally will travel for major sporting events," said White, who was anticipating a 40,000-plus crowd on Friday.

"I'd like to think that the fact we've got two massive events on (in Brisbane) with us playing the Cowboys and the Roar playing the A-League grand final we will both benefit from it this weekend.

"Suncorp Stadium is a wonderful facility to watch any sport. Hopefully we (Broncos) can gain some impetus from this weekend."
