Victorian accounts manager Benjamin Norris not only became $250,000 richer tonight but also the first gay man to win the Australian version of Big Brother when he was left the last housemate standing for 2012.
After spending 85 days in the Gold Coast complex, Norris could barely contain his shock when host Sonia Kruger announced his name over fellow finalist, British beautician Layla Subritzky, on the live show.
Law student Estelle Landy came in as second runner up when she was evicted halfway through the broadcast with the lowest percentage of votes to win out of the final three.
The final leaderboard had Norris with 40 per cent of the vote, Subritzky with 31 per cent and Landy with 29 per cent, which was in stark contrast to the results on Sunday that pegged 'Gangstella' as the frontrunner.
Norris spent his last moments in the house walking from room to room chanting, "I won, I won" before Kruger joined him in the house for a heart to heart.
The 32-year-old said his win had left him speechless.
"I've never really won anything in my entire life," he said.
Norris later shared a tearful reunion with his partner Ben on stage before delivering another jaw-dropping twist - by proposing to his love with an heirloom family diamond.
Ben accepted, yelling: "I'm engaged."
