It's a day for us to celebrate diversity and stand against discrimination in support of lesbian, gay, bisexual, transgender, intersex, and queer (LGBTIQ) mates, colleagues and families.
We're asking everyone to show their support by Wearing It Rainbow, put on your most colourful clothes to celebrate and stand united.
We're also asking you to sign a pledge supporting LGBTIQ people, and showing your stance against discrimination.
Keep an eye on Facebook and Instagram for more details.
