What are the national guidelines and which edition do they come from?

The Australian Sports Commission (Sport Australia) partnered with the Australian Human Rights Commission and the Coalition of Major Professional and Participation Sports (COMPPS) to develop the "Guidelines for the inclusion of transgender and gender diverse people in sport". Sport Australia's page says they offer practical advice that helps sporting organisations build inclusive environments for trans and gender diverse people.

Edition: the guidelines are the 2019 edition, as the Australian Institute of Sport's page refers to them as the "2019 AHRC Guidelines". The Sport Australia pages themselves show no edition or last-updated date.

The online version has section 4 ("What does the law say?") and section 5 ("How can my sporting organisation be inclusive?"), and the Sport Australia page also lists a Reflective Practice Framework, resources, FAQs and case studies.
