On this day in 1975: South Australia became the first state in Australia to decriminalise homosexuality. The reform was sparked in part by public outrage over the m**der of law student George Duncan in 1972, a case that exposed police violence and rallied public support for change. It marked the beginning of a decades-long push for LGBTQ+ law reform across the country, culminating in nationwide decriminalisation by 1997. #OnThisDay #LGBTQHistory #Australia #QueerRights
