Even stricter face mask rules and travel restrictions have been introduced in Sydney to force the city's coronavirus outbreak under control.
NSW Health Minister Brad Hazzard ramped up restrictions as the citywide lockdown enters its third week after a record-high 50 cases on Saturday.
Residents will have to wear masks in more places - including their own apartment buildings - and everyone outside Sydney banned from coming in.
But a respected expert claims this will not be enough and a draconian lockdown similar to Melbourne's stage-four, with troops on the street to enforce it, is needed.
New face mask rules and travel restrictions have been introduced in Greater Sydney with a draconian-style lockdown and troops on the street possibly on the way, a top epidemiologist has warned
Residents will only be able to travel to Greater Sydney to access goods and services that are not available in their area
Under the new restrictions coming into effect this week, residents are only be able to travel to Sydney to access goods and services that are not available in their area.
Travelling into the area for exercise or outdoor recreational activities is no longer a valid reason.
They are also only be allowed to travel to attend a funeral or memorial service as long as there are no more than 10 mourners.
Sydney residents wanting to leave the area must also carry identification that contains their residential address.
Face masks must also be worn at indoor construction sites at all times.
On Tuesday, the restriction will be extended to all indoor common property areas of residential premises in Sydney, the Blue Mountains, Central Coast, Wollongong and Shellharbour.
Residents who live in apartments will be required to wear the extra protection when taking the lift or waiting in the lobby.
Epidemiologist Tony Blakely warned the restrictions are not tough enough and suggested the city should be placed into a much tougher lockdown with soldiers patrolling the streets.
Dr Blakely said the state government had three options: Let the Covid-19 outbreak circulate in the community, continue with a partial lockdown, or deploy troops and police to patrol the streets.
'The third option is the only one. It's very hard to say those words: 'We're going into a hard lockdown, we've called in the military, the police and we are going to police it,' he told news.com.au.
'It's not a pretty look but if you want it to be over and done with as quickly as possible that, most unfortunately, is what needs to happen.'
The draconian lockdown would be similar to the one introduced in Victoria last year - which lasted 111 days.

Non-essential businesses were closed, an 8pm curfew enforced and a ring of steel placed around Melbourne with residents only allowed to leave their homes and exercise within a 5km radius.
Police patrolled the streets and were assisted by military troops during the tough three months.
Dr Blakely warned continuing with a partial lockdown meant Sydney might only begin to reopen in September.
'If they keep going the way they are now, without really stepping it up now it could go on for months,' he said.
The additional face mask and travel restrictions were introduced by NSW Health after it announced it would be tightening lockdown across Sydney from 5pm Friday.
Exercising outdoors must be limited to groups of two and people must stay within 10km of their homes when exercising.
Residents in Sydney, the Blue Mountains, Woollongong, Central Coast, and Shellharbour are in the midst of an already extended three week lockdown - with the premier hinting another extension was not off the table.

Can you still exercise outdoors?
Yes, but in reduced groups. Locked down residents from Friday evening will only be allowed to exercise outdoors in groups of two - down from the 10 previously allowed.
The only exception to this rule is members of the same household already living together can exercise outdoors together.
