Matt Doran sparked concern among viewers after he mysteriously disappeared from Weekend Sunrise last week.
The 41-year-old failed to arrive to the Seven studios and left producers scrambling to find a fill-in host, The Daily Telegraph reported.
He was replaced by news reporter Chris Reason who returned to host the breakfast show alongside Monique Wright on Saturday.
A Channel Seven spokesperson told Daily Mail Australia, Doran is currently ‘on leave’.
Doran’s disappearance comes one year after he sparked a frantic police search after vanishing during a work assignment in the Hunter Valley in June last year.
The star reporter had been sent to cover a wedding bus crash that claimed the lives of 10 people but failed to show up for his 5:30am shift on June 13.
Insiders said when producers went to look for Doran in his Singleton hotel, knocks on his door when unanswered.
The high-profile crime reporter had last been seen speaking to members of the Singleton community at a local football ground.
Earlier, locals had seen Doran leaving the home of newly married couple Mitchell Gaffney and Maddy Edsell, whose wedding was at the centre of the tragedy.
When the reporter failed to answer calls, texts and emails ahead of his scheduled appearance on Sunrise, a producer went to check his hotel room.
Worried colleagues contacted police, who issued a missing persons alert.
Doran was eventually found at a nearby café and was swiftly replaced by his colleague Liam Tapper on air.
Insiders say several factors could have contributed to his troubling behaviour, with one suggesting Doran may have struggled with the confronting nature of the wedding bus crash tragedy.
Doran took several weeks of personal leave after he vanished in the Hunter Valley and was reportedly spending time at home ‘prioritising his health’.
He was replaced by his colleague Michael Usher on Weekend Sunrise.
Doran, who started his career as a police reporter at the Herald Sun, joined Seven in 2017 after spending almost eight years in Network Ten’s newsroom.
Two years later, he was promoted to his current role as co-host of Weekend Sunrise, alongside Monique Wright, after intermittently filling in for weekday host David Koch.
