If You Are The One is based on the format of Australian show Taken Out, which aired on the Ten Network in the late noughties.
Each episode of the hit Chinese show starts with presenter Meng Fei welcoming "24 beautiful girls" who walk onstage two-by-two to the sound of upbeat pop music.
He said for a short while his parents thought they might have to learn Mandarin."It was a big fright for them at the time," he said.
Mr Mc Mahon said the experience made him realise that Chinese was going to play a large part in his life."In Chinese there is an idiom that goes along the line of, 'from a tragedy comes something great'," he said."I really want to dedicate my life to forging better cultural communication and understanding between China, Australia and the rest of the world."Mr Mc Mahon said he had been following If You Are The One since the show began five years ago."I've always wanted to go on this show but it's never seemed to be the right time," he said.
Shortly after returning to Australia in 2012 he was in a serious car accident and fell into a week-long coma."When I came out of that coma, the first words to come out of my mouth were in fluent Mandarin," he said.
He said he opened his eyes to see a nurse of Asian appearance and spoke to her in Mandarin, saying: "Hi, it really hurts here ... " For some time after the accident he would think and dream in Mandarin, he said, and sometimes would lapse into Mandarin when conversing with his English-speaking friends and family.
The man is introduced to the women in a series of up to three videos, interspersed with onstage conversations mediated by the host.
The show is a cultural phenomenon in China, where each episode is watched by up to 50 million people.
The episodes, filmed in the Chinese city of Nanjing, will go to air on SBS2 over two Sunday nights, starting this Valentine's Day.
Mr Mc Mahon learned Mandarin in high school and after graduating spent time backpacking in China and studied Chinese in Beijing.
