More than 900 people have been infected in Nsw since the Bondi cluster was discovered last month.
The outbreak has led Victoria – which is due to begin a snap five-day lockdown of its own from midnight on Thursday – to close its border with Nsw and Act as of this week, with Queensland also extended border restrictions to all of Greater Sydney, including the Central Coast, Blue Mountains, Wollongong, and Shellharbour.
Meanwhile, Western Australia has reinstated border restrictions with Queensland and Nsw, while South Australia has closed its border with Nsw, the Act, and some parts of Queensland. Tasmania remains closed to people from greater Sydney.
The rise of the Delta strain is another blow to productions that have already had to navigate the unpredictable nature of the pandemic.
