Sunrise host David Koch has tested positive to COVID-19, a day after appearing at the Australia Unites broadcast.

All attendees at the Nine-hosted event were required to undertake a test prior to entry.

“I tested negative on Saturday lunchtime ahead of the Australia Unites broadcast but then woke up feeling a bit shaggy on Sunday morning, which I initially put down to the late finish and sharing the bottle of red wine that Sylvia (Jeffreys) and Dr Chris (Brown) insisted we share (that’s my version and I’m sticking with it),” Koch said in a statement.

“But then I tested again and it came in positive. Symptoms are mild and I’m following the health orders.”

Both Sylvia Jeffreys and Dr Chris Brown have both reported as negative.

The Daily Telegraph reports no other attendees have tested positive at this stage.
