Dubbo MP Troy Grant visited the centre on Monday to present their annual funding under the Intervention Support Program, and manager Janelle Burke said the money would enable the centre continue "critical" early intervention support.

"It gives little children with additional needs a better start to their schooling so it helps them to achieve their milestones and their goals," Ms Burke said.

"Dependent upon the needs of the individual children we have access to doing home visits, we do childcare service visits as well or we run some specific education sessions in the centre.

"We are very family-focused in that we want to empower all of our parents to become the early intervention teachers and therapists for their children but we work very much in partnership with them as well."

The centre has grown phenomenally in recent years and now employs 17 educators, therapists, administration and management staff who supported more than 250 families in 2015.

"As they say investing in early intervention you pay $1, it saves $7 down the track so if we can invest as much as possible in those early years hopefully we're going to not have to be investing as significantly in later life," Ms Burke said.

"That's probably one of the big things that we've seen increase - that the diversity and complexity of needs is just increasing phenomenally so that's a challenge for our staff as well."

Mr Grant said the Intervention Support Program funding would help OECI to improve educational opportunities, learning outcomes and personal development of children with a disability.

"It's vital support for children with disability and their families to improve their participation and educational achievement, and prepare them for inclusion into early childhood programs and school," Mr Grant said.
