Cameron Merchant and Jules Robinson take their baby Ollie on his first trip to the aquarium

Married At First Sight stars Cameron Merchant and Jules Robinson celebrated one of their son Ollie’s first milestones on Sunday – a trip to the aquarium.

Former cricketer Cam shared adorable footage of baby Ollie, seven months, marvelling over sea life during a visit to the Sydney Aquarium.

Ollie smiled and giggled in his pram as fish, stingrays and even a shark swam above him in the large tank.

At one point, Jules appeared emotional as she held Ollie in her arms to get a closer look.

While little Ollie loved the aquarium, he wasn’t so impressed with his parents’ singing abilities.

Cameron posted a funny picture of Ollie after they sang Baby Shark with the rest of the parents at the aquarium.

Cameron and Jules are the most successful couple the controversial reality show has ever had.

And last month, Cam shared his almost-daily gushing tribute to his ‘everything, superwoman and best friend’.

The post was shared alongside a loved-up of the duo, with Jules’ impressive diamond engagement ring on full display 

‘I have no idea how you do what you do but I am so thankful for you, am in awe of you everyday & just so proud of you & everything you do with a smile on your face,’ the 37-year-old wrote.

He praised Jules for her tireless work on her underwear and lingerie brand Figur, adding: ‘I trust that all your dreams will come true cause you deserve them.’ 

Cam told Who magazine on Tuesday he remains forever ‘grateful’ for Married At First Sight and can’t wait to show his son how he and Jules met. 

‘It has been a magical journey and we certainly look forward to showing Ollie how his parents met one day. That’s something that no one’s ever going to take away from us,’ he explained. 

So in love! Last month, Cam shared his almost-daily gushing tribute to his 'everything, superwoman and best friend', his wife Jules

Cam went on to suggest the couple’s popularity is down to not getting caught up in the ‘glitz and glamour’ of television.

‘We want to keep the real in everything we do,’ he said.

‘We were two, three, seasons ago [in 2019] but we still have a connection to so many people out there who find us relatable, everyday people.’ 

Cam and Jules, 38, met on season six of Married At First Sight, which was filmed in late 2018 and aired early the following year.

The reality TV couple legally married in November 2019, selling broadcast rights to their wedding day to A Current Affair.

They welcomed son Oliver on October 3 last year.

Announcing her pregnancy in April, Jules told Stellar magazine: ‘I’ve had my moments – times of sadness, fear, despair and tears, fuelled by hormones. We’re all in this together, though. It has to be okay.’

Cam and Jules had tried throughout 2019 to conceive a child, but had faced difficulties because of Jules’ age.   

‘Because of my age I had done all the hormone testing, the egg count… so much is instilled that you’re going to struggle because of your age,’ she said.

‘Once it was all confirmed, I bawled out of pure joy and happiness. To create a baby with the man you love, there is no greater gift, and Cam will be one incredible father.’
