MAFS STAR DEAD Trisha Stratford dead: Married At First Sight Australia star dies aged 72 as emotional tributes pour in

MARRIED At First Sight Australia star Trisha Stratford has died at the age of 72.

The clinical neuropsychologist provided expert advice on the popular dating show from when it first hit TV screens in 2015 until her departure in 2020.

Trisha's MAFS colleague and fellow original expert John Aiken announced her death on Instagram.

“I’m heartbroken and devastated that my friend and dear colleague Trisha has passed away,” he wrote alongside photos of himself with Trisha.

“We shared an amazing seven seasons of MAFS together.

"She loved everything New Zealand, relationships, the All Blacks, the Black Caps, French wine and travelling the world. I’ll miss you, Tish.

"Thank you for all the memories."

Channel Nine said the network was “deeply saddened” to hear of Trisha's death.

“Our sincerest condolences and heartfelt sympathies go out to her family and those closest during this difficult time,” the spokesperson said.

Trisha's cause of death is unknown.

The New Zealand-born relationships expert announced she would be leaving the show in 2020 - and moving back to her home country from Sydney.

“After seven seasons of Married At First Sight I have decided to step back from the television series to focus on my writing, research and neuropsychotherapy,” she said at the time.

"The program provides a platform for an ongoing conversation on relationships and I wish the program continued success and hope future participants find everlasting love."

She was replaced by clinical sexologist, Alessandra Rampolla.

Before her stint on MAFS, Trisha worked for 60 Minutes as a war correspondent in Somalia and Bosnia.

She leaves behind her daughter Gina and one granddaughter.
