Big Brother Australia has sent home its resident geek, Bradley Darke aka B-Rad.

B-Rad hints no regrets, though. The 19-year-old has learned so much from the Big Brother house, and he is coming home a positively transformed young man. He even sounds ready to embark on a new chapter now that he has "changed a tonne."

"I have changed a tonne in the past two months. I think I have grown more in the house than in my entire life," Darke said.

If there is one thing Darke now seems very eager to try, it is the set of lessons he learned from former housemate Josh.

"Josh gave me some advice...I have to have a drink in my hand, which was a soda water with a bit of lime, go out on the dance floor so then when a girl goes up to the bar I can follow, give her a compliment and start a conversation."

Asked how he would open the conversation, the teen known for his geekiness told news.com.au:

"I can't repeat them in a PG newspaper, it will have to be saved for the moment."

Staying in the Big Brother house was not the easiest adventure for Darke. But he takes note of the happy memories, all thanks to his housemates. Darke said they made him feel "comfortable and accepted for being me."

Darke's speech problem, particularly the stutter when he's stressed, was one of the challenges he wanted to overcome. His housemates showed him it was not a burden he should overthink.

"It was so positive to have the house accept me for being me. They accepted (the speech impediment) and even had fun with it," he said.

Darke says his best memory in the Big Brother house is the celebration of his birthday with the theme superhero. Each nomination night, on the contrary, proved horrible.

"Each Monday after I'd been nominated...that's probably when I felt the most down in the house...it hit pretty hard. The first time I was able to shake it off and the second wasn't all that much different. But the third and fourth time were just a bit too much," Darke said.

Now Darke does not have to worry about evictions, anymore. But he has his whole life ahead of him post Big Brother Australia.
