Businesses can choose whether to require customers to have My Vaccine Passes as a condition of entry. For some businesses, this decision will affect the rules they must operate under.
From 11.59pm, 4 April 2022, businesses will no longer need to sight customers’ My Vaccine Passes in order to operate (or operate with fewer restrictions).
The COVID-19 Protection Framework rules, such as capacity limits, will apply to all businesses, regardless of whether they require My Vaccine Passes.
If they wish, most businesses have the option of limiting access to their premises to people with a My Vaccine Pass (as a condition of entry).
