The ground zero of NSW's bushfire emergency response has been commandeered to wage the state government's war against the coronavirus.

Experts from more than 20 critical agencies are now consolidated under one roof, including the Health, Police, Education and Transport departments to co-ordinate the state's response to the virus.
