Infectious disease experts say the Morrison government should release the scientific modelling underlying its response to the deadly coronavirus, warning the public may grow tired of restrictions if they are not given access to the detailed expert advice.

Raina MacIntyre, head of biosecurity at the NSW Kirby Institute, said Australia should follow the lead of the United Kingdom, New Zealand and United States in making its modelling public to "inform the community and elicit their cooperation".

"The purpose of modelling is to inform disease control strategies, and to engage and bring people along with the necessary measures to control COVID-19," Professor MacIntyre said.

Deputy Chief Medical Office Paul Kelly on Wednesday appeared to backtrack from an earlier commitment to "unlock" the modelling, saying it could be misinterpreted.
