"For several months, Rugby Australia has been in possession of a transgender participation guideline developed by World Rugby in consultation with developmental biologists, medical experts and sport scientists. The World Rugby Guideline runs to 38 pages. It has a reference list of 45 scientific reports. It finds that it is neither safe nor fair for transgender players who are biologically male to play in women's rugby, demonstrating with significant rigour that a situation where a male player tackles a female creates "a minimum of 20 to 30 per cent greater risk for those female players". Rugby Australia is yet to respond to this document or release it publicly. On Thursday, Rugby Australia released its own trans inclusion guidelines. It contains no references to scientific reports and doesn't mention the World Rugby findings of significantly increased head and neck injury risk to female players. It lays out a procedure to allow biological males identifying as women to play women's rugby."
