VICTIMS of gay hate crimes in SA will be able to make anonymous online reports to the police.

The AIDS Council of South Australia and SAPOL hope the online reporting system, launched tomorrow, will encourage more victims to come forward and expose their tormentors.

The launch follows the clash between supporters at a gay and lesbian rally and a "right wing" Christian group outside Parliament House on Saturday.

AIDS council social and cultural research officer, Holley Skene, said similar schemes interstate had given her the idea to adapt it for South Australia.

"Research suggests that hate speech and hate crime often go unreported," she said.

"In part, this is because victims feel uncomfortable revealing their sexuality to law enforcement authorities. SAPOL does not currently collect data on homophobic and transphobic crimes at all."

The AIDS Council will monitor the reports and refer serious matters on to the police for further investigation. The reports will also be used to measure the level of gay hate crimes.

The online reporting system will be launched as part of IDAHO day tomorrow, the International Day Against Homophobia and Transphobia. The online report form is at www.

acsa.org.au/idaho.html under the heading "Report Homophobic and Transphobic Behaviour or Violence".

Senior Constable Phil Gurr, who co-ordinates SAPOL's gay and lesbian officer network, said officers had been helping to set up the online reporting system.

"SAPOL strongly recommends that all incidents of crime should be reported to the police, however, we also acknowledge that victims of these types of crime will often not report these matters to the police," he said.

ACSA chief executive Shane Dinnison said more could be done in SA to address the health needs of people marginalised because of their sexuality.

"No South Australian health plan or strategy lists gay, lesbian, bisexual, transgender and intersex populations as vulnerable and therefore no provisions have been made to target this group," he said.

Victims of Crime Commissioner Michael O'Connell welcomed the initiative as an example of how "all crime victims should be treated with respect and dignity".
