The first doses of the Australian-made AstraZeneca coronavirus vaccine are on track to be ready by the end of March.
Prime Minister Scott Morrison visited Melbourne-based biotechnology company CSL on Friday, where the vaccines are being made.
The vaccine is awaiting final regulatory approval from the Therapeutic Goods Administration, with its production entering the final stages next week.
Mr Morrison says more than a million doses will be produced each week from late March.
"That's a big production effort and that is going to change the country for the better," he said.
"And for those who are producing that here, we just simply say thank you for the service that you're providing to your country."
Local manufacturing of the University of Oxford developed vaccine has been under way since late last year at CSL's manufacturing facility in Victoria.
Each batch will undergo quality checks by CSL, AstraZeneca and the TGA.
The medicine will be formulated to a precise concentration, filtered and visually inspected before going into 10-dose vials.
