NSW has reported 239 new cases of community-transmitted coronavirus.
Premier Gladys Berejiklian told reporters on Sunday most of the cases are in Sydney's west and southwest and pleaded with residents to get any Covid vaccine available to them.
“Having said that, we don't want to see the virus spread further and we certainly don't want to see households, whole households become infected because one person has brought the virus into their home," the premier said.
“Today is August 1 and I am calling upon the people of Greater Sydney, greater New South Wales to come forward and get vaccinated.
"To get to the 70 per cent target we need 9.2 million jabs. To get the 80 per cent target we need 10 million jabs. We have been talking about this in New South Wales for some time.”
More than 21,300 Covid-19 vaccines were administered in the 24 hours up to 8pm on Saturday. In total, more than 3.8 million doses have been given in NSW by the health department and a further 2.3 million by GPs.
Of the 54 people in intensive care for Covid in NSW, 49 were not vaccinated. The other five included on person who had their first dose of Pfizer and four others who had their first AstraZeneca vaccination.
Premier on Queensland, Victoria lockdowns
Ms Berejiklian was asked whether she underestimated the Delta variant of Covid-19 and if she regrets not locking down sooner like her Queensland and NSW counterparts.
Victoria came out of lockdown on Tuesday after bringing in restrictions on July 15. Queensland re-introduced a lockdown on Saturday at 4pm which at this stage is expected to last until Tuesday.
Meanwhile, NSW's lockdown is scheduled to finish on August 28. Greater Sydney and surrounding areas have been under lockdown for a month already.
But the premier said "there is no roadmap for the Delta variant" and "no perfect way" to deal with it.
“The benefit of hindsight is a great thing to have but other states might be facing regular lockdowns in and out all the time, what I am saying for New South Wales is we want this to be, yes it is painful, but we want this to be the last lockdown we have and we can make that happen if we get vaccinated," she said.
"We knew early on this was a scary variant.
"We also never know, this is a challenge with Delta, the undetected strains of transmission which may have been in the community and that is really critical to assess.”
Will the lockdown end on August 28?
Ms Berejiklian said she believes "of course" NSW can turn the outbreak around by August 28.
“There are a lot of things dependent on that. Firstly, high rates of vaccination, especially in southwestern and Western Sydney where we know the virus is particularly virulent,” she said.
“Secondly, people continuing to do the right thing and higher rates of testing.
“We know that we have been successful in preventing thousands and thousands of cases until this point in time.
“But we also know how challenging it is to reduce the number of cases that we have, but with higher rates of vaccination we can do it.
"With higher rates of testing we can do it and let's make August the month where more and more people come forward and get vaccinated because the vaccine is protecting human life, is bringing people out of hospital but it is also helping reduce the spread.”
Two days of more than 200 new local cases has led to several additional Covid exposure sites including Target and IGA.
People who visited close contact venues are being asked to get tested immediately and self-isolate for 14 days regardless of their test result.
Visitors to casual contact venues will have to get tested and self-isolate until they receive a negative result on their Covid-19 test.

Covid deaths occurring at homes

He added "sadly" one death "a couple of days ago" was a person subsequently diagnosed with the virus after they died.
In total, 14 people have died from Covid-19 in the latest NSW outbreak.
