A few gay bars attempt to restrict entry to only gay or lesbian people, but in practice this is difficult to enforce. Most famously, Melbourne's Peel Hotel was granted an exemption from Australia's Equal Opportunities Act by a state tribunal, on the grounds that the exemption was needed to prevent "sexually-based insults and violence" aimed at the pub's patrons. As a result of the decision, the pub is legally able to advertise as a "gay only" establishment, and door staff can ask people whether they are gay before allowing them inside, and can turn away non-gay people.
