The woman previously accepted that she did the wrong thing, and despite arguments the security guard's tackle was too heavy, she said she "got what I deserved".
Speaking to Tammy Barker & Bodge for Breakfast on Triple M Cairns following the incident, Ms Johnson admitted she got swept up in the moment.
"I know exactly what I did. It's been a bucket list thing and when your friends say, 'I dare you to do it', you don't actually think you're going to do it. It was such a surreal, out-of-body experience," she said.
"It's the adrenaline of the crowd. You just hear this big roar and I was like, 'I need to take off my top now'. I was so close to doing my bra but I was like, 'No … that's a bit far'."
The pitch invader also elaborated on why she had no issue with how the security guard handled her situation.
"I used to play AFL and rugby and I have three brothers, so getting tackled was not a problem," she said
"The tackle was honestly fine, it was more how much air I got. I guess it just looks so much worse. He could have just grabbed me at that time and I would have fallen over.
"I think it's fair play. I definitely took what I deserved. He should keep his job."
Johnson's stunt came after she uploaded a TikTok video from the stands, saying: "One of my actual biggest goals in life has been to actually just run on the football field and I'm doing this, ready? I'm going to."
Johnson also re-posted footage on TikTok of her getting tackled by security and in another clip she shared media articles about her stunt and a text message from a person she suggested was her boyfriend.
A screenshot posted on the social media platform revealed the text message said: "You're an idiot and a disgrace. Thank you for an absolute embarrassment. Don't try contact me."
Johnson captioned her TikTok post: "When your man doesn't come to the footy but wakes up to this…".
