Elyse Knowles and Josh Barker have welcomed their first child together. 

The couple, who won The Block together in 2017, shared the exciting news on Instagram on Monday night. 

"The next chapter in our lives. The best chapter yet," Elyse wrote on Instagram, alongside a very cute black-and-white photo of their baby's feet. 

While they didn't announce the sex of the baby, they did share their child's name, Sunny Barker.

Josh shared an identical post over on his Instagram. 

The couple first announced they were expecting a child together back in September last year. 

"And then there were three," Elyse wrote on Instagram at the time with the hashtag #babybarker.

The couple posed, with a heart drawn on Elyse's stomach, in front of Uluru where they're currently holidaying.

Elyse, 28, and Josh, 31, have been together for seven years after meeting in Josh's hometown of Byron Bay in 2013.

The couple have lived in Elyse's home in Melbourne for most of their relationship, with their two weimaraners, and in 2017 appeared on The Block - taking out the competition when their renovated house was sold to comedian Dave Hughes, pocketing them a cool $547,000 in prize money.

Elyse was a successful Australian model prior to appearing on the show, working for brands like Billabong and Seafolly, but the show's publicity sent her profile skyrocketing - and in 2018 she took over as Myer brand ambassador from Jennifer Hawkins. 

Speaking to Mamamia in 2018, she admits the considered backing out of The Block at the last minute.

“We worked so hard to get on the show, and then we found out we got in, and we kind of had this shock feeling of, ‘Oh my God. Imagine if this is going to have a negative effect on my career. I’ve been working so hard since I was 10 years old on modelling, is this going to make me or break me?’ It was a really big chance that I took,” she said.

Elyse says that ultimately her experience on the show made her and Josh even “stronger” as a couple.

“You learn a lot about each other… To get through that together, you kind of feel like you can get through anything,” she told Mamamia.

The couple shifted to Byron Bay in early 2019 and in a blog post, Elyse documented how much she loved her new home's environmental consciousness.

She said while Melbourne was always home, she had fallen in love with the relaxed Byron lifestyle.

"Don't get me wrong, I adore Melbourne and I will certainly miss my family and so many elements of that beautiful city (which is my home!). 

"But for this stage of my life, I am exactly where I need to be. Literally! As I am writing this it's 7pm, warm & balmy and I am outside in my bathers taking it all in. One happy little Vegemite."

In August 2019 Elyse told the Daily Mail she saw their move being permanent and imagined raising a family in the area.

"It's a great change for us... a sea change and a lifestyle change. I do love Melbourne and it's always home for me, but at the moment I think we'll stay for good. I can see us bringing up our own family [in Byron Bay]."

In May the couple purchased a 1960s beach house in the town - a perfect renovation project for the couple and their business J & E Projects.

In December 2019, Elyse told Gritty Pretty she wanted to start a family before she turned 30.

"I just keep thinking that my mum had me at 28 and oh my gosh, I need to get going," she said.

"I want one or two kids by 30... I just don’t want to wait until too late in my life. I'd rather put family first and then career."

She said Josh doesn't like talking about getting married, and the couple were keen to go at their own pace despite outside pressure.

"[Josh] very much likes his own rule book and I'm totally okay with that, too. I think we're on our own journey and we're happy at the moment," she said. 

Josh told WHO Magazine in June 2019 marriage wouldn't change anything in their relationship.

"I think we’ve just both got separate dreams and ambitions and stuff that we want to achieve together," he said.

"It's not gonna change anything... Other than the ring, that's it. And a bit of paper that you'd get and end up putting in your bloody side drawer. I've had so much outside pressure but I'll do it when I'm ready."
