Melbourne community radio station JOY 94.9 FM was forced to evacuate its studios on Tuesday night after receiving a bomb threat, the latest in a string of intimidating messages the LGBTIQ organisation fears will only worsen ahead of the potential marriage plebiscite.

They evacuated the studios as per the organisation's emergency response plan, which was updated shortly after the Orlando nightclub shooting in the US in June.

The program on air at the time the threat was received was Beyond The Binary, a show for trans and gender-diverse youth.
