Anne-Marie Best, of Brandy Hill, has already helped inject almost $44,000 into regional towns through her We Care Road Trip bus tours.

But she knows the drought is so fierce across the state that the contribution has barely scratched the surface.

She said so many small businesses were feeling the pinch because farmers didn't have the money to spend.

Some businesses have already been forced to close their doors, and many more fear they will have the same fate if nothing changes.

With the Bureau of Meterology predicting lower than average rainfall, and higher than average temperatures, for the next three months, their plight is unlikely to change anytime soon.

The NSW government's Combined Drought Indicator shows 63 per cent of the state is drought affected, 19.8 per cent is in drought and 14.3 per cent is suffering intense drought.

"This is something everyone can do to make a difference," Ms Best said.

"If you are thinking about going away for a weekend, or thinking about planning a holiday, choose to visit a town that is affected by drought.

"Each time a business is lost it is a huge loss to that town, and it often means they can't access that service in town anymore and have to drive a long way to another town."

In Moree, which is one of the worst-hit areas, businesses are struggling to stay afloat.

Dibs Cush, who owns Robin's Nest for Children and is the Moree Chamber of Commerce treasurer, said sales were down 30 to 40 per cent on a good year and some of the town's businesses had already been forced to shut their doors.

"If people don't support us we won't be here. Our locals can't sustain us, we do need that tourist dollar and I do worry that there is no future for independent boutiques in every small town," she said.

"Inverell, which is the biggest town to the east of us, has lost a significant amount of shops including their bookshop and a toy store just in 2019.

"When there is no rain, there is no crops and when there is no crops the farmers, which are our predominant industry, aren't spending money and that really affects us.

"We are feeling the affects of drought across the entire retail sector but also our agriculture suppliers like our tyre places, the spare parts people are feeling the pinch."

Ms Cush encouraged tourists to drop in and plan ahead so they could use some of the towns services while they were there.

Moree Tyrepower owner James Von Drayen is usually very busy helping farmers and has had to refocus on suburban-based customers in a bit to stay afloat.

He has done his best to keep his staff because they need wages to pay their bills and be able to stay in the town.

He said there were many reasons to visit Moree, including the Moree Artesian Aquatic Centre, other artesian hot pools in the area and the golf course.

"Everyone has to be our customers because farmers aren't spending money. We have to go out and try to get our share of the market," he said.

Mr Von Drayen said state and federal governments had to step in to support small businesses.
