Alongside the Western NSW Local Health District, the ADF will be in 33 communities in 23 days, giving thousands of local residents the chance to get vaccinated.

The clinic in Orange will be open for five days from September 6.

Chief Executive of the Western NSW Local Health District, Scott McLachlan, said the operation would start in West Dubbo with a walk-in clinic opening at 9am on Saturday, August 21 at Pioneer Park.

There will be five mobile teams, involving at least 72 ADF personnel, with each team supported by healthcare workers, including Aboriginal health workers.

"Over a three-week period the mobile teams will spend between one and five days in each location, offering free COVID-19 vaccinations. At the end of that initial three weeks, the teams will go back again to deliver the second dose. Both AstraZeneca and Pfizer vaccines will be available, depending on each person's eligibility," Mr McLachlan said.

On average it's expected the mobile service will be able to offer up to 300 vaccinations, and in a site like that set to pop-up at West Dubbo, the capacity could be as high as 600 doses per day.

"We've seen the Delta strain of COVID-19 attack our communities and while the current lockdown should help, getting vaccinated is clearly our best weapon," McLachlan added.

"The vaccine can help stop you getting COVID-19, and if you do get it, the vaccine will mean you're less likely to get really sick, or pass it onto someone else.

"This is an incredible opportunity for these communities. Having the ADF involved means we can do this on a scale we couldn't have imagined a few weeks ago."

Mr McLachlan said that vaccination hubs in Dubbo, Orange and Bathurst would also be stepping up their activities.

"Our hub sites will be expanding their hours and given the current situation in Dubbo it's a real focus of our attention," said Mr McLachlan.

"I want to say to everyone in our District that this is a golden opportunity. If you've already been vaccinated, or you have an appointment coming up soon - thank you and keep those appointments by all means."

Orange mayor Reg Kidd thanked Nationals MLC Sam Farraway for his support in getting the vaccination hub at Orange and maintaining a level of communication between local and state government.

"We as a community are being pro-active in this battle, and playing 'the blame game' is not a solution," Cr Kidd said.

"A big thanks to all the health workers and to the community for a job well done to date. Remember, get out and get tested and vaccinate."
