* Students who were due to return from holidays next week will mostly learn from home, but schools will be open for children of essential workers.
* Ms Berejiklian warned case numbers would spike in the coming days due to the highly infectious Delta strain spreading rapidly in the local government areas of Fairfield, Liverpool and Canterbury-Bankstown.
* She said if the situation further deteriorates in those communities, harsher localised restrictions could come into force.
* The decision to extend the lockdown has left Sydney's hospitality, entertainment and travel businesses "devastated".
* Queensland recorded one new locally acquired case of COVID-19 as government hopes grow that the state's five outbreaks are under control.
* Premier Annastacia Palaszczuk said the new case in Tarragindi, in Brisbane's south, is a contact of a known case and was already in home quarantine.
