 When the Council was being reformed in the 1970s, Turner appeared before a Parliamentary Committee as an expert witness.With other colleagues, he made an influential contribution to the design of the scheme of public funding for elections adopted in NSW

In 1985 came The Wran Model, another Department of Government project which Turner facilitated and co-edited (with Ernie Chaples and Helen Nelson).It remains the definitive account of NSW politics and elections in the 1970s and 80s.
