The Roar averaged crowds of 9,632 last season, compared to the highs of 14,957 during the 2013/2014 campaign.

Brisbane won just four games last season and finished second-last on the table.

The Roar host Melbourne Victory this Friday in their first home game and new recruit O'Shea admits his team have to make a good impression with their fanbase.

"First impressions are going to be big for us," the winger said.

"It would be nice to go out there and get a positive result and hopefully get more members coming and trying to get big crowds back at Suncorp again. In any season your home form is massive.

"If you want to do anything you need to picking up wins at home. We’re all gelling well. It was a long pre-season and it gave us a chance to get to know each other."

O'Shea joined Brisbane from English club Bury.

The attacking midfielder has yet to visit Suncorp Stadium but is looking forward to it.

"It’s going to be good," he said.

"A lot of us here will be making our home debuts. I’ve heard lots of good things about the stadium, it looks amazing. I haven’t been there yet. I’m looking forward to going there when there’s a good crowd there.

"Under the lights it should be good on Friday. We’ll go there and train, it would be good to go there and get a look."

Brisbane opened the A-League season with a 1-1 draw away from home against Perth Glory.

The Irishman declared it as a positive result for the Roar.

"It’s definitely a positive result," the 31-year-old said.

"They won the league last year… I don’t think anyone on TV or radio gave us a chance. Getting a point away from home against the league champions last year is a great result for us."
