"It was a difficult decision but we have decided to part ways," the couple said in a joint statement to TheFIX.
"We remain the greatest of friends and we will continue to be part of each others’ lives. We thank you for your privacy at this time.
The pair struggled with long-distance, with Simon based in Queensland and Alene in Sydney, but kept their love alive through phonecalls and romantic getaways.
‘We are enjoying the distance relationship,’ Alene told The Daily Telegraph after the series ended.
‘The show just finished so we are just trying to learn the ropes. I have a lot to organise in my life and so does Simon so we aren’t planning too far ahead.’
Despite their attempt at making it work, Alene admits the commitment became tough.
"The long distance has been hard," the 31-year-old said. "I come home on a Friday night and I call up Simon and I'm like, "Let's go out!" but obviously, that can't happen."
