Sydney could be stuck in lockdown for months longer than expected because only 40 per cent of residents are actually staying home, expert modelling claims.
The modelling predicts that if 80 per cent of Sydneysiders were compliant, case numbers of the Delta variant would be in single figures.
But if compliance fell to 70 per cent, it would take until late September to control the outbreak.
Sydney appeared to be on its way out of lockdown as cases dropped from their peak on Monday to 65 on Thursday, but then rose to 111 on Saturday.

Mikhail Prokopenko, director of the University of Sydney’s Centre for Complex Systems, said Sydney’s social distancing was woefully inadequate.
‘Our estimation shows that with only 40 per cent of people staying at home, that would be inadequate even for a less transmissible variant, and for Delta it doesn’t even scratch the surface,’ he told The Australian.
‘If that trend continues then the incidence numbers will not start reducing, they will keep growing and the lockdown will continue.’
Professor Prokopenko said it was vital people reduced the frequency of their grocery shopping each week as well as other activities such as exercising beyond an hour or catching up with friends.
These would have to drop to 10 per cent of normal activity of the city was to have a chance at getting out of lockdown soon.
He added he was bewildered by the repeated level of non-compliance with public health orders imposed by under-siege state governments.
‘Some people have a legitimate reason not to stay at home because they’re engaged in essential services,’ Professor Prokopenko said.
‘Maybe 30 per cent are doing essential services and maybe the other 30 per cent are simply not complying.’

Research from the Burnet Institute also found tougher restrictions would be required to effectively control the outbreak of the Delta variant in NSW.
On Saturday morning, scores of people were spotted out and about at Rushcutters Bay in Sydney’s east as well as Manly on Sydney’s northern beaches.
Social distancing was non existent and groups exceeding two were in every direction as police struggled to enforce the mandatory public order requirements.
In Victoria, currently enduring their fifth snap lockdown, saw 19 cases of coronavirus recorded on Saturday.
That figure was almost double the 10 diagnosed on Friday after the Delta strain began spread in Melbourne when infected removalists from NSW passed it on.

Further restrictions have since been introduced, with thousands of Sydneysiders to be locked in their neighbourhoods, most shops shut, and ‘non-urgent’ construction banned until at least July 30 as Covid cases spiked above 100 again.
The new restrictions announced by Ms Berejiklian on Saturday aim to completely shut down the southwest Sydney epicenter of the outbreak.
A man in his 80s from south-west Sydney was the confirmed death.
‘I can’t remember a time when our state has been challenged to such an extent,’ Ms Berejiklian said. ‘Not a single one of these decisions was taken lightly.’
