One of them, Challenge Children's Services, will provide foster care, respite and residential care for children and young people.

The parent-driven organisation has moved into premises on the old Lourdes Hospital site at 80-110 Cobbora Road.

NSW Minister for Disability Services and Ageing Andrew Constance will visit Dubbo on December 11 to officially open Challenge's new home and tell the public about the extra services.

Currently Challenge provides support to 65 people with disabilities through its Dubbo Day Program and Transition to Work services.

Its new initiatives include "the first respite service for people with a disability and their families in Dubbo" and Challenge Education Training Services, a registered training organisation helping people expand their skills in the disability and care industries.

Challenge Children's Services completes the set.

"People who may be interested in becoming foster carers are encouraged to contact Challenge Children's Services in regards to the many opportunities becoming available in the region," chief executive officer Barry Murphy said.

He calls the move to Lourdes "a major win" for the expanding organisation.

"Challenge Dubbo has continued to grow due to the terrific support received from the local community," Mr Murphy said.

"We are really looking forward to offering a broad range of services."

The organisation was launched 50 years ago by a small band of parents and friends seeking support services for children with disabilities.

Currently it provides more than 600 client services for people with a disability or mental health illness across the north-west, central west, New England and Hunter regions of NSW.

Its headquarters are in Tamworth.

The public is invited to attend the official opening at Lourdes on December 11 from 3pm.

Light refreshments will be provided.
