Dr Danny Sullivan of Forensicare believes the drug could stop convicted paedophiles, rapists and killers from reoffending.

The drug has been used in the US, and Dr Sullivan says it has been proven to have success rates in reducing offences from those who have taken it.

“In Oregon, the government passed legislation in the early 1990s that all sexual offenders leaving prison would be assessed for medication to reduce their sexual drive,” he told ABC’s 7.30 programme.

“And the published studies very clearly have shown that those assessed as needing it and who took it, reoffending rates were extraordinarily low.”

Zolodex is given as a quarterly injection and without the Pharmaceutical Benefits Scheme costs $1,500 per jab.
