In 1981, Richard Harding, after reviewing Australian and other data at that time, said that "whatever arguments might be made for the limitation or regulation of the private ownership of firearms, suicide patterns do not constitute one of them. " He quoted a 1968 international analysis of twenty developed countries "cultural factors appear to affect suicide rates far more than the availability and use of firearms. Thus, suicide rates would not seem to be readily affected by making firearms less available." however, in 1985 Harding later supported laws to restrict gun ownership in New South Wales, saying laws contributing to slowing down in the growth of the Australian gun inventory are to be welcomed.
