"I talked the talk so I had to walk the walk."

That's how streaker Ben Jenkins justified his nude dash at Optus Stadium during the $1.5 billion venue's first sporting event.

The 23-year-old, from the WA Wheatbelt town of Toodyay, ran onto the field during the 17th over with only his girlfriend's number scribbled on his arm, so he could call her from the lock-up.

Mr Jenkins scaped the clutches of security twice before surrendering in the middle of the pitch.

In an exclusive interview, Mr Jenkins told 9NEWS he had been on a three-day Australia Day weekend bender with his friends leading up to the One Day International cricket match, all the while planning to become the first streaker at Perth's newest venue.

"For a couple of days, I was saying look I want to be the first streaker at Optus Stadium," he said.

"I really want that title.

"Went past the security guard, and thought 'yep I've got a bit of distance here', and thought 'yep I've got a bit of time'.

"So chucked my wallet and phone to my mate, and said here we go."

Mr Jenkins said he nearly backed out at the last minute but eventually mustered the courage.

"I sat there for a long time, I was looking at every security guard and the path I was going to take and I was just thinking, 'I really don't want to do this anymore'," Mr Jenkins said.

"Peer pressure won.

"When the time was ripe and the clothes came off, there was no turning back."

The risqué stunt has earned the plumber and gas fitter both praise and abuse online and on talkback radio.

Mr Jenkins was ejected from the ground and issued with a move-on notice by police.

He is also facing a fine of $5000 and has now launched a crowdfunding page to pay the charge.

High-profile Perth lawyer Tom Percy will represent Mr Jenkins for free at his impending court appearance.
