I almost forgot to say the words . . . Will you marry me? 

Benjamin Norris, the 32-year-old from Victoria who won $250,000, was clearly making a public stand for gay marriage (and a very public declaration of love) when he produced a diamond ring for his partner, also named Ben. The pair hugged emotionally, before Ben added "I almost forgot to say the words ... Will you marry me?"

"This is the diamond my great-grandfather bought for my great-grandmother and it was there on my parents' wedding day," he said.

"Since I met Ben, I wanted him to be part of my family," he added.

Host Sonia Kruger seemed a little stunned by the surprise proposal, which came in the final moments of the grand finale show.

The couple, nicknamed "the Benjamites" had already garnered huge attention and support within the gay community.
