The state's disability liaison service will also be expanded by 16 officers.
From 8 October, all state-run vaccination centres will be accepting residents with a disability without a booking.
As of 30 September, more than 71 per cent of the state's National Disability Insurance Scheme (NDIS) participants aged 16 and over had received their first dose of a vaccine, Mr Donnellan said. The national average, he said, is 67 per cent.
"So, we're doing slightly better, but it's simply not good enough," he said on Thursday.
"Vaccination for Victorians living with a disability are still lower than the general population ... at 84.4 per cent. We've got to keep pushing through."
The two new deaths reported on Thursday include a woman in her 60s from Wyndam and a woman in her 70s from Hume.
There are 564 Victorians in hospital with COVID-19, with 115 of those in intensive care and 74 on ventilators.
Of the people in hospital, 66 per cent were unvaccinated, 27 per cent were partially vaccinated and seven per cent were fully immunised.
Fifty-five per cent of the population over the age of 16 is fully vaccinated, while 84.4 per cent have had their first dose.
The new infections form the second highest daily case tally for the state's third wave, and take the number of active infections across the state to over 15,000.
In the 24 hours to midnight Wednesday, 36,672 vaccines were administered at state-run hubs and 77,000 tests were carried out.
