NSW’s task of winning this year’s State of Origin series just got tougher with Suncorp Stadium set to be at 100 per cent capacity for next week’s decider.

Queensland premier Annastacia Palasczcuk revealed on Friday her government was easing several COVID-19 restrictions from 4pm Tuesday, including the limit on open-air stadiums to operate at 75 per cent capacity.

The decision means an extra 12,500 fans can be allowed to attend Wednesday’s game three with a potential attendance of 52,500.

With the borders closed between NSW and Queensland, Blues’ fans will be in the minority at the venue, where NSW have won just twice since 2010.

“I think Queenslanders are going to be very, very happy with this outcome,” Palaszczuk told reporters.

“Let’s fill Suncorp and cheer our mighty Maroons on.”

Despite their impressive record at Suncorp Stadium, with 37 wins from 58 Origins at the ground, Maroons’ utility Ben Hunt says the venue won’t decide the game.

“We need to go up a level for sure,” Hunt said.

“We were nowhere near where we needed to be (in Sydney), so yeah we need to improve a hell of a lot.

“We can’t just rely on the crowd.”
