From Monday, March 15, staff at nine Victorian hospital vaccination hubs, including Goulburn Valley Health, started delivering second doses to priority workers.
Hotel quarantine workers, airport workers, frontline health staff and residential aged care residents and workers are the first to receive their second jab.
With 35,282 doses administered state-wide, the Victorian Department of Health said it remained "on track" to deliver all vaccines supplied by the Commonwealth.
“Victoria . . . is expanding the rollout to include more locations for Victorians in the Commonwealth’s priority groups to receive the vaccine,” the department said.
The news comes as a host of European nations, including Spain, France, Italy and Germany, temporarily suspend the AstraZeneca vaccine rollout due to concerns over blood clotting.
Australia has secured 53.8 million doses of the vaccine, most of which will be produced in Melbourne.
Federal Treasurer Josh Frydenberg said on Tuesday, March 16, the AstraZeneca vaccine remained safe and there was "no evidence of causation" between the vaccine and the blood clots.
Interstate, NSW and Queensland have not recorded any further local cases of COVID-19 overnight.
The Victorian Department of Health has been contacting all arrivals to Victoria from Sydney since March 13 following a positive case in a hotel quarantine worker.

NSW Health added the Hurstville Aquatic Leisure Centre and Coles Hurstville Station to a list of places visited by the security guard, and said anyone who visited the venues on March 10 between 4.15 pm and 5.30 pm, and 9.15 pm and 9.46 pm respectively should monitor for symptoms.
Department staff have also been contacting all arrivals to Victoria from Brisbane since March 10, after a positive case was found in a doctor at the Princess Alexandra Hospital.
