The first streaker at the Perth Stadium has been labelled "an idiot" and a "show pony" by a magistrate, who told the 23-year-old to "grow up", saying people "are sick of exhibitionists like you".
Ben Jenkins has pleaded guilty to trespassing on the playing field at the stadium's first sporting event in January — a one-day cricket international between Australia and England in January.
The Perth Magistrates Court heard Jenkins talked about becoming the first streaker at the stadium when he was watching another cricket match on television in the days before.
He went to the game and, egged on by friends, wrote his girlfriend's telephone number on his arm so he would know who to call when he was arrested. He then took off his clothes and ran onto the field.
Play was stopped for about a minute before he was crash-tackled and dragged off the ground by security guards.
Jenkins's lawyer, Simon Watters, said his client, who was not affected by alcohol, had made a foolish mistake and "deeply regretted" what he had done.
Mr Watters said Jenkins had received a hate letter at his home and had also been banned from entering any licensed premises for six months.
He told the court his client, who was a talented footballer and did volunteer work, had references from people who described him as "a person of good moral character" and a "great leader".
Mr Watters said the offence was out of character, prompting Magistrate Ed De Vries to suggest that he was "probably also a bit of a show pony".
"People are sick of exhibitionists like you," he told him, before citing the case of cricketer Terry Alderman, who he said suffered a serious injury "because of idiots running onto the field like you".
"Do you think you might grow up?" he asked Jenkins, who replied, "Yes, I do".
Magistrate De Vries fined him $2,000 and granted him a spent conviction order, which means he will avoid a criminal record.
In granting the order, Magistrate De Vries told Jenkins he was "sure" he was of good character "apart from the fact you like exposing yourself in front of thousands of people".
Jenkins made no comment as he left the court.
Immediately after the offence, Jenkins was banned from attending Cricket Australia-sanctioned matches for three years.
