FULL strength beer should be banned in corporate boxes at the new Perth Stadium, according to Mark McGowan.

The Premier made the remarks while over-ruling his Sports Minister Mick Murray on whether full strength beer should be permitted at day games when the stadium opens next year.

Mr Murray told The Sunday Times it was his preferred position for beer to be available as full strength during the day and restricted to midstrength at night to curb fans who had been “pre-loading” during the day.

But Mr McGowan said he had a “bit of a difference of opinion” to Mr Murray and favoured the midstrength-only arrangements currently in place at Domain Stadium, regardless of the time of day.

“I’ll make a submission to the Liquor Commission along the lines that I think that the midstrength arrangement works,” he said, before going further.

“I have a view that if there’s going to be midstrength for the crowd there should be midstrength for the people in the boxes.

“I don’t think it should be a two-tiered system.”

Mr McGowan conceded that wine was currently available at Domain Stadium but only in “very small cups”.

“So I think the midstrength arrangement and small cups are ways of restricting people’s drinking habits,” he said.

“But I just make the point again. I don’t understand why people in the boxes have a different arrangement to people in the crowd. That’s obviously something that I'd urge the football administrators and the Liquor Commission to investigate.”
