Book excerpt: Since the Second World War the Australian military has undergone remarkable transformations in the way it has treated lesbian, gay, bisexual, transgender and intersex service members: it has shifted from persecuting, hunting and discharging LGBTI members to embracing them as valued members who enhance the Force's capabilities. LGBTI people have served in the Australian military since its very beginnings, yet Australian Defence Force histories have been very slow to recognise this. Pride in Defence confronts that silence. It charts the changing policies and practices of the ADF, illuminating the experiences of LGBTI members in what was often a hostile institution. Drawing on over 140 interviews and previously unexamined documents, Pride in Defence features accounts of secret romances, police surveillance and traumatic discharges. At its centre are the courageous LGBTI members who served their country in the face of systemic prejudice. In doing so, they showed the power of diversity and challenged the ADF to make it a far stronger institution.
