Macarthur's vaccination rates continue to grow as the state gears up for additional freedoms to those who are fully vaccinated in coming months.
The Camden Local Government Area (LGA) is still leading the way in the region with more than 90 per cent of eligible residents having received their first dose.
Macarthur MP Dr Mike Freelander took to Facebook to celebrate the milestone of 91.5 per cent.
He said the region was achieving some 'incredible numbers'.
"Again, Macarthur residents are leading the charge when it comes to rolling up their sleeves and getting vaccinated," Dr Freelander's post stated.
"As of yesterday, 91.5 per cent of eligible Camden LGA residents have had their first dose, and 87.1 per cent of Campbelltown residents have had theirs.
"Thank you Macarthur, and a massive thank you to the health care workers and support staff who are keeping us all safe."
Almost 50 per cent of residents in Camden and Campbelltown have also received their second dose.
In Campbelltown 47.9 per cent of eligible residents are fully vaccinated with 49.4 per cent of Camden residents having received their second jab.
Camden is ranked among the top five Greater Sydney LGAs when it comes to vaccine uptake in recent months.
It follows The Hills District, Blacktown and Ku-ring-gai local government areas.
The 2570 postcode region, which crosses both Wollondilly and Camden LGAs, and the neighbouring 2557 postcode region are leading the way with vaccine rates in the area with more than 90 per cent of its residents having received their first dose of the vaccine.
NSW Health's priority 16-to-39 vaccination blitz is still under way in south-west Sydney.
Young people are being urged to make a booking at the South Western Sydney Vaccination Centre at Macquarie Fields, Liverpool Vaccination Clinic, Prairiewood Vaccination Clinic and the Bankstown PCYC Vaccination Clinic.
