Tourism operators said visitor numbers to Orange had fallen in the past few weeks with Sydney people staying at home instead of travelling across the fire-ravaged Blue Mountains and Lithgow areas.

However, businesses will benefit from this weekend's arrival of the first of about 1000 people for the Western NSW Junior Cricket Carnivals.

Spread over two weeks the carnivals have enticed 32 teams of under-13 and under-15 players and their families from Sydney, regional NSW, the ACT and New Zealand to Orange.

But, Orange District Junior Cricket Association president Jo Hunter said they would not include a planned under-13 team from India.

She said the entire team had been refused visas to enter Australia by Australian authorities.

Mrs Hunter said negotiations were continuing about whether an Indian under-15 team would be allowed into Australia.

A Shoalhaven team has also pulled out due to the fires.

The Indian under-13 team has been replaced by a Sydney invitational team.

She said about 25-30 people were part of each team who would take accommodation in motels, Airbnbs, hotels, apartments and being billeted with Orange families.

"Some people will bring their whole family and have their holiday," she said.

Mrs Hunter said the visitors would be buying food, shopping, going to the Aquatic Centre and Tenpin Bowl and dining out, particularly at family hotels.

Orange360 general manager Caddie Marshall said the carnivals would bring about $2 million into the economy. "These sporting events have been fantastic for our region. They always bolster the visitor economy," she said.

Ms Marshall said the cricket event would fill up many of the region's 2400 visitor beds.

She said tourist numbers had been down due to the fires. "I think most of NSW has just been halted by the fear of the impact of the fires," she said.

Montoro Wines owner Bob Derrick said he had seen a fall in cellar door visitors in recent weeks.

"They're not coming out at all," he said.

Mortimers Wines owner Peter Mortimer said visitor numbers had fallen in the past four weeks after a strong previous year of business.

"We're not getting the incidental [visitors]," he said.

De Salis Wines owner Charlie Svenson said cellar door numbers were down by about 50-60 per cent as the public heeded safety warnings.

"Everyone's business [was] struggling in December," he said.

"People have stopped discretionary travel over the Blue Mountains."
