Contact tracing will be mandatory for hospitality venues from November 13, however patrons will be able to drink standing up and Christmas parties can double in size.
The new measures form part of a Summer Social Package, announced by Premier Peter Gutwein on Friday, aimed at increasing safety and providing more certainty for businesses heading into the Christmas period.
Mr Gutwein also announced that from next Friday, contact tracing would be mandatory for hospitality venues, with the details of patrons to be kept for 28 days.
This includes the name of a patron, the time of entry and a contact phone number.
However, Mr Gutwein said only one person per group would be required to sign in.
"At cafes, restaurants, pubs and clubs where people spend reasonable amounts of time and as our border restrictions continue to ease, collecting patron information will be vital in curbing a potential outbreak in our state.
"Consideration for further settings will be undertaken by Public Health in the further weeks."

"Further work is being done on an electronic solution, knowing that already in the marketplace there are a number of electronic solutions."
Mr Gutwein said the government was working to establish a legal framework to ensure the information collected is only used for the purposes in which it was collected.
In regards to "vertical drinking", Mr Gutwein confirmed that from November 13, patrons would be able to drink standing up in the outdoor areas of hospitality venues only.
This would be kept under review, with further consideration for indoor areas to made closer to Christmas.
