Up to 100 pop-up respiratory clinics will be established around the nation to fight the spread of coronavirus under a $2.4 billion federal government plan that also includes subsidised video-link consultations and a targeted public health campaign.

The specialist treatment centres in areas of greatest need will divert Australians with mild or moderate symptoms away from strained emergency departments and local clinics so they can handle the more severe cases.

Prime Minister Scott Morrison will unveil the measures on Wednesday to combat the advance of COVID-19 ahead of the expected release of a multibillion-dollar stimulus package later this week to help cushion the economy over the coming months in a bid to stave off a recession.

The health package will contain a $30 million national awareness campaign to begin within days, targeting those most at risk of contracting the disease, with television, radio, print, digital and social media advertisements.
