The wedding comes days after Jesinta downplayed marriage rumours on the Today show, but she did reveal the couple had planned a month-long holiday.

Host Lisa Wilkinson asked: 'You are not going to go away and elope? You are not going to rob us of the wedding moment are you?'

Jesinta replied: 'No, for us, this year for us was focusing on health and happiness and getting through the year.'

'So the wedding is still on hold at this point?' Lisa asked again, to which Jesinta responded: 'Yes.'

Meanwhile, Jestina told the Courier Mail in May the pair would 'probably just elope' and 'keep it very simple' when they decide to marry.

She added: 'It won’t be a Big Fat Greek Wedding. I’ll just come back and be Mrs Franklin and that will be it.'

The couple had previously postponed their wedding, which was originally scheduled to take place in January this year.

It was once rumoured they would be married by the end of 2015, but Jesinta said this was 'not true at all'.

She previously told Fairfax Media: 'We've actually never set a date for the wedding.

'We always wanted a long engagement and to enjoy it. There has never been any rush for us. And it's not really going to be a big affair anyway.'

By his side: Jesinta loyally supported Buddy throughout his struggle with mental illness

After dating for 14 months, Buddy proposed in December 2014 with a custom-designed 4.5 carat diamond ring by Nader Jewellers.

The Asscher cut sparkler has an estimated worth of between $75,000 and $100,000, Sydney fine jeweller Emma Swann told Daily Mail Australia.

The actual price has never been confirmed, but Patrick Nader revealed he worked with Buddy for 'about a month' to get the ring 'just right'.

Shortly after Buddy proposed, Jesinta wrote on Instagram: 'I cannot wait to spend the rest of my life with you. There are no words to describe how happy we are.'

In September 2015, Buddy stepped away from Australian Rules football due to an 'ongoing mental health condition' and epilepsy.

But he made a triumphant return to the AFL in March, kicking a goal in the opening minute in his comeback match against Collingwood.

Jesinta loyally supported Buddy through his struggle and later claimed he was making steady progress.

In the weeks following his decision to go public with his health problem, Jesinta spoke about the difficulties he had been facing.

'He's put his hand up and said "I'm struggling, I'm struggling and I need help and I'm getting help",' she revealed.

Out of the blue: The surprise marriage comes after a difficult year for the high-profile couple

Later, Jesinta confessed the stressful situation had 'taken its toll' on her.

She told The Sydney Morning Herald in November last year she sometimes found herself 'in tears on the way to work'.

Jesinta first rose to fame as the Australian representative at the Miss Universe 2010 beauty pageant.

She then capitalised on her success with ambassador roles, modelling gigs, TV work and property investments.

She has worked with major brands, including David Jones, Wonderbra, and Westfield over the years.

Her public profile increased further when she accepted Buddy's marriage proposal almost two years ago.

Buddy is widely considered one of the best AFL players of the modern era.

He has played nearly 250 games for Hawthorn and Sydney and kicked 787 career goals.

He played in the 2008 and 2013 premierships at the Hawks before signing a nine-year deal worth $10million with the Swans.

It is the most lucrative player contract the AFL has ever seen.
