A year-long investigation into the use of banned substances in Australian professional sport has found the use of drugs is "widespread".
The Australian Crime Commission (ACC) said scientists, coaches and support staff were involved in the provision of drugs across multiple sporting codes, without naming any individuals.
Speaking following the publication of findings, Sports Minister Kate Lundy vowed to "hunt down" those involved.
