Chlamydia pecorum  is an established and prevalent infection that produces severe clinical disease in many koala populations, contributing to dramatic population declines. In wild South Australian koala populations,  C .  pecorum  occurrence and distribution is unknown. Here,  C .  pecorum- specific real-time quantitative PCR (qPCR) was applied to ocular and urogenital swabs from targeted surveys of wild koalas from the mainland Mount Lofty Ranges (MLR) (n = 75) and Kangaroo Island (KI) (n = 170) populations. Historical data from 13,081 KI koalas (1997–2018) provided additional evidence for assessing the absence of  C .  pecorum  infection. In the MLR population, 46.7% (CI: 35.1–58.6%) of koalas were  C .  pecorum  positive by qPCR but only 4% had grade 3 clinical disease. MLR koala fertility was significantly reduced by  C .  pecorum  infection; all reproductively active females (n = 16) were  C .  pecorum  negative, whereas 85.2% of inactive females (n = 23) were positive (P < 0.001). KI koalas were  C .  pecorum  negative and the population was demonstrated to be free of  C .  pecorum  infection with 95% confidence.  C .  pecorum  is a real threat for the sustainability of the koala and KI is possibly the last isolated, large  C .  pecorum -free population remaining in Australia. These koalas could provide a safeguard against this serious disease threat to an iconic Australian species.
