Assistant Minister for Health Fiona Nash has admitted a drug and alcohol resource library run by a body she cut funding to was not being offered by any other organisation, despite citing duplication as justification for her decision.

The Alcohol and Other Drugs Council of Australia, which has operated since 1966, was placed in voluntary administration in November after its funding was cut. It will close at the end of the week.

Senator Nash told an estimates hearing on Wednesday she had received requests to meet with the chief executive and board of the council, but had not done so, because she received an "enormous amount of requests to meet."
