An additional 17,500 additional Pfizer doses have been allocated to the Illawarra Shoalhaven - with residents aged 12 to 59 years to be given priority access.
The additional Pfizer doses, allocated by the Commonwealth Government, will arrive in the region from next Monday.
Wollongong's Mass Vaccination Centre will be the first to deliver the additional Pfizer doses, with further rollout to Shoalhaven Hospital's Vaccination Clinic expected over the coming weeks.
The Wollongong centre has been running at limited capacity since it opened in August - offering around 700 Pfizer jabs a day when it has the capacity to do 2500.
Illawarra Labor MPs, including opposition health spokesman Ryan Park, have been calling for additional supplies for weeks.
The district's Executive Director Nursing and Midwifery and Clinical Governance, Deborah Cameron, has welcomed the allocation.
"We know people have been eagerly awaiting the Pfizer vaccine, and our staff will be working hard over the next few weeks to vaccinate as many people as possible," she said.
"This significant supply boost will also allow us to direct more Pfizer doses to our outreach and mobile vaccination programs, aimed at protecting our most vulnerable communities against COVID."
Bookings are essential and will be available via the Eligibility Checker from September 20. People will receive appointments for both doses of the vaccine upon registration.
Those with an existing Pfizer appointment will receive a text message or email inviting them to log-in to the Vaccination Booking Portal and move their appointment forward, prior to appointments opening to the wider eligible public on Monday.
Those requiring assistance with rescheduling or making an appointment can submit an enquiry via the ISLHD website or call the Bookings team directly on 1300 096 365.
People must not attend their vaccination appointment if they have any COVID-19 symptoms and should get tested and self-isolate until they receive a negative test result. People should also stay home if they are a close contact of a confirmed case.
