Studio 10 has been thrown into disarray after one of its hosts tested positive for COVID-19.
Tristan MacManus had just finished filming Wednesday morningโs show when a rapid antigen test determined he had contracted the virus.
The positive test result meant co-host Sarah Harris was forced into isolation, prompting former Bachelor Matthew โMatty Jโ Johnson and reporter Lachlan Kennedy to step in.

Network 10 has contingency plans in place to ensure the impact on its program schedule is minimal. The health, safety and welfare of all staff and the wider community remains Network 10โs number one priority.โ
On Thursday morningโs show, Sarah and Tristan appeared from their respective homes via video link.
โI am back sleeping in a spider-man bed for the first time since I was 12-years-old,โ Tristan laughed.
โYesterday when we came into work, I was feeling a bit shady. I was really tired and hadnโt slept the night before and was really cold. I put it down to the fact Iโve got three kids.โ
โAs the day went on I started to feel better but I thought it would be the responsible thing to take a RAT test at home, which I did and unfortunately it came up positive.โ
Sarah, 40, revealed she has taken three rapid antigen tests since Sunday, two of which came back negative. However, a third test this morning registered a faint line that could mean she has also contracted COVID.
โThere is the faintest little line. I have been looking it up on the internet because apparently that is all you can really do, if there is a line there, you have to isolate until you are clear,โ she said.
โBut I feel absolutely fine. Itโs like, โWhat next?โ I guess I take a test and wait but obviously those PCRs are being reserved to those who need them.โ
