Almost three-quarters of Australians would back a Covid-19 vaccine passport, a new poll shows, as health officials weigh up a potential nationwide policy.

In the first survey of Australian attitudes to a jab mandate, 73 per cent of respondents agreed the government should make it compulsory for work, travel and study.

David Smith, the lead author of the University of Sydney and University of Western Australia study and an associate professor at the United States Studies Centre, noted that was more than the 66 per cent who reported they would get the shot voluntarily.
