The program, Day to Day Living, run by Catholic Health Care, helped people with severe and profound mental illnesses to develop and regain skills, and to be part of the community.

Catholic Health Care coordinator Carol Johns said the activities involved visits to coffee shops and to locations outside of Orange, such as Echuca, Lightning Ridge, Penrith and the Blue Mountains.

"Because people with severe and profound mental illnesses keep themselves a bit [private], it is about bringing them back out into the community," she said.

"The group has become like friends so when the program finishes they can still be in contact with one another.

"Over the years we had up to 90 odd volunteers."

The initiative, which had 13 clients, will end on June 30 due to the transition of disability funding to the National Disability Insurance Scheme. Now clients will choose other similar services through are part of the NDIS.

Catholic Healthcare Home and Community Services regional manager Narelle Pabis said the program was originally funded through the federal Department of Health through a different funding stream.

"It was always going to transition out," Mrs Pabis said.
