While they don’t serve full-strength beer at Optus Stadium to the general public, it clearly still hasn’t deterred people from being rowdy.

More than 33,000 fans headed to Perth’s newest attraction on Saturday to see the Dockers beat the Suns by 28 points, and they also witnessed an event you’re more likely to see at a rock concert.

During the clash a woman somehow duped the overwhelming security presence at the ground to make her way onto the field, with nothing else but a bra on her top half.

It’s unclear how long the woman tried her hand at full-forward approximately eight minutes after the final siren, but the video shows security finally catching her to guide her off the field.

Camera Icon Security eventually caught up with her.

It’s not the first time Optus Stadium has had issues with the fans trying to join in the on-field action. In January, 23 year-old plumber Ben Jenkins invaded the field fully nude during a one-day international cricket clash between Australia and England.

For that incident, Jenkins was charged with trespassing – an offence carrying a maximum penalty of 12 months in prison and a $12,000 fine.

Optus Stadium officials said on Sunday that two women had entered the playing field when there were no players or officials on it.

WA Police arrested the women, who have already been handed three-year bans to the stadium.
