Riverina Murray Regional Alliance made a submission to the inquiry, arguing that the centre is needed for its clients, who stretch from Albury to Wagga.

RMRA chairperson Ruth Davys said such a centre could address drug issues while connecting people to their Aboriginal culture.

"The RMRA envisages the benefits of the development of a holistic cultural facility in which alcohol and other drug rehabilitation can take place in a culturally safe space, run by Aboriginal people, on land we own in our community," she said.

"Which also fosters other community activities including language learning, connection with elders, and employment opportunities.

"Such a space would be able to accommodate a user's family and allow the user to remain on country.

"In-reach services could be provided by non-Aboriginal service providers in a way that is culturally appropriate."

The RMRA is in the process of developing an accord with the government and its own ice strategy.

One idea was for a rehabilitation facility similar to the Marrin Weejali Aboriginal Corporation, which helps Aboriginal people in the suburbs of Western Sydney.

Ms Davys said the model was also suitable for youths in the Riverina, including the ability for family to join the participant in the rehabilitation process, which she said was "essential".

"There needs to be a recognition that a significant barrier to Aboriginal people accessing drug and alcohol treatment is that a particular service is not provided by Aboriginal people," she said.

"I am finding a want for increased youth-related support in our community, mainly among those disengaged in school and on the verge of engaging with the criminal justice system."

Hearings in the inquiry took place between March and September in Sydney and regional NSW.

The commission was established by the NSW government to look into the nature, prevalence and impacts methamphetamine, as well as options to strengthen the state's response, including law enforcement, education, treatment and rehabilitation.

It will report to the NSW Governor by January 28 next year.
