New guidelines encourage sporting organizations – including coaches, umpires, staff, players, spectators and volunteers – to permit transgender and non-binary athletes to compete against members of the opposite sex, welcome transgender and non-binary athletes into bathroom and shower facilities designated for the opposite sex, place disposal bins for used female hygiene products in male change rooms, convert some or all facilities to “unisex / gender neutral” to accommodate non-binary athletes and provide “non-gendered uniforms” that fit the physique of both sexes.
It is a breach of the guidelines for players to refuse to compete against or participate on a team with transgender and non-binary athletes, fail to affirm their gender with preferred pronouns, say they are in the wrong bathroom or change room, or ask about their bodies.
