It didn't take long for the compliments to come rolling in - and to say some were thirsty is an understatement.
"Looks like my future husband," remarked one fan.
"*Every girl on Instagram," noted another, followed by a drooling face emoji.
Even former Bachelor season six star Brooke Blurton commented: "Loving the hair! Looks great!"
Since his time on The Bachelor, Matt has laid relatively low and used his social media profile to mainly share space related content and adorable pictures of his dog, Pluto.
Two months after the finale Matt and his winner Chelsie parted ways but the astrophysicist told the Herald Sun that he wasn’t in “great shape” after leaving the Bachelor mansion.
“It was very intentional,” he said of his decision to step back from the limelight.
“It was an element of normality I was seeking, but the big thing for me was I was just putting myself back together.
“I did not come out of both the show and the relationship in great shape and I needed time with my close friends and family to pick myself up and put myself back together, really.”
Whilst Matt appears to still be single, his ex Chelsie is all loved-up with her new model boyfriend, Ricki Dehaan.
The couple went Instagram official at Christmas with a sweet photo of them kissing in front of a festive display.
As for runner-up Abbie Chatfield, she can now add Queen of the Jungle to her resume following her I'm A Celebrity...Get Me Out Of Here! victory when she beat fan favourite Grant Denyer for the title.
