Orange double bass players Dr Sam Kwa and Dr Ian Carter will be joined by medicos from around Australia for four days.

The visit will culminate in a recital in Orange on Sunday March 15.

Dr Kwa said it was the first time the orchestra had performed in Orange.

They performed in Hobart and on the Sunshine Coast last year.

"I've been with the the Australian Doctors Orchestra on and off for 20 years," he said.

Dr Kwa said the orchestra was formed before his involvement.

"There was a realisation there were a lot of doctors who were very musical," he said.

Rehearsals will be held at the Orange Regional Conservatorium in the lead up to the sold-out concert at the Orange Civic Theatre.

There will also be a civic reception for the doctors and their partners on Friday March 13.

The visit is also set to provide a valuable boost for the local economy.

Dr Carter said some of the doctors were expected to stay on and see the sights of the region.

"It's a little winner. It's a good one for the town," he said.

Dr Carter said he joined the orchestra in 2015.

He said doctors were coming from as far away as Darwin.

Proceeds from the concert ticket sales will go to the Orange Push for Palliative Care advocacy group.

President Jenny Hazelton said it was a welcome fundraiser.

"We are extremely appreciative members of the medical profession participating have decided to support our group," she said.

A 12-month trial for providing palliative care in Orange at Uniting Parkwood has been extended by three months to the end of June.

Mrs Hazelton said they wanted the four-bed facility to become permanent.

The Western NSW Local Health District is reviewing the project.

"We want absolute continuity. It is making a lot of difference to families in Orange," she said.

Mrs Hazelton said that if Parkwood became permanent the money raised by the orchestra recital would be used to help create a palliative care community garden on site.
