New South Wales Police have reviewed 86 historical cases over the past three years after a report by the Australian Institute of Criminology questioned whether some cases had been sufficiently investigated.

27 deaths have been revealed to have been hate crimes. Police have acknowledged previously they had played a part in "marginalising" the LGBTQI community.

It found that hate crimes were either confirmed or suspected in 27 deaths, and that further investigation was needed in another 25 cases.

The report said the level of violence towards gay men during the period was "extreme and often brutal". Men were often found dead in parks and at the bottom of cliffs near known LGBTQI beats in Sydney.
