In the bridal party were Mitcham’s three siblings and Rutherford’s two brothers and two best girlfriends.
Rutherford’s niece was flower girl while his mother performed the ceremony.
However, sadly, not all of Mitcham’s family were able to make it to the ceremony in Europe, with his grandparents unable to fly over and his uncle is currently in quarantine as one of the passengers on the coronavirus hit cruise ship, the Diamond Princess.
“Luke organised a big surprise video montage of messages from people who couldn’t make it,” Mitcham explained.
The couple also wrote their own wedding vows.
“After a sustained period of lovely gestures, loyalty, gazing adoringly and many trips to Ikea, I managed to trick Luke into falling in love with me, proposing to me and finally marrying me,” Mitcham wrote on Instagram. “Now he’s stuck with me forever and ever, ha!”
Mitcham – who won gold at the 2008 Beijing Olympics - was the first openly gay athlete to win an Olympic gold medal when he came out before winning the 10 metre platform event
He also recorded the highest ever Olympic score for a diver, 112.10.
The former athlete made headlines when official broadcaster NBC didn’t show the Australian athlete hugging and kissing his former partner Lachlan Fletcher during his victory lap of the pool.
Mitcham now focuses on performing his cabaret show around the country and is a strong advocate for marriage equality.
