Dubbo Chamber of Commerce president Matt Wright said there were going to be some businesses that would be doing it "pretty tough".

Under the restrictions put in place on Wednesday, most retail premises are required to be closed to the public, however there are businesses providing essential products and services that can open.

Some industries have already been hit by the Greater Sydney lockdown starting on June 26, and Dubbo's COVID situation was a new blow.

"We're going to have some businesses there that will be doing it pretty tough," Mr Wright said.

"Those restaurants, cafes, even accommodation providers who have been doing it pretty tough since school holidays, since the Sydney metropolitan lockdown, they're going to feel it even more so than many other businesses.

"So our thoughts go out to them."

In the hours before the lockdown, Mr Wright said "from all reports, supermarkets are very busy" and he also urged community members to resist panic buying.

"Supermarkets will remain open even during the lockdown period so there is no need for panic buying," he said.

"There's plenty of stock available and people can continue to go, there's a huge list of businesses that will remain open, even during the lockdown period and the chamber will promote those through our database and get the link to that website on our Facebook page and our chamber website.

"There's no need for panic, and I know people like to stock up, but there will be an opportunity for people to continue to visit the shops and get what they need over the lockdown period."

Mr Wright also asked consumers to exercise patience.

"There's a lot of business owners out there that are trying to abide by health orders so show some patience and understanding to not only those business owners, but also to fellow shoppers that are out there just doing what they're trying to do," he said.

The chamber president encouraged the community to keep supporting Dubbo enterprises during the lockdown.

"....a call-out to locals to continue to utilise those businesses that have the option of takeaway and try to continue to spend money in the local area while we're in a lockdown period," he said.

A Business NSW survey of members in July showed revenue in western NSW was down by as much as 40 per cent in some sectors.

When asked what he would say to businesses who might be feeling like Dubbo's lockdown was the last straw, Mr Wright said he hoped it wasn't and urged businesses to reach out.

"Communities, especially regional communities do band together very well, and when the opportunity comes for locals to support locals, they really do come to the fore," he said.

"Let's just try to get through this next week to 10 days and as people get back out and about in the community again, we'll hopefully start to see money flowing back through those businesses again.

"So hang in there and reach out to fellow business owners for any sort of support, or to the chamber of course, if they want to have a conversation."
