We report five cases of Rickettsia australis infection from southern coastal New South Wales, Australia. All patients presented with a cutaneous eruption of erythematous papules and pustules and systemic features of malaise, headache, lymphadenopathy and myalgia. Acute kidney injury (AKI) was present in two of five cases and one of five cases had acute delirium. Improvement was only seen after treatment with doxycycline 100 mg b.i.d. Positive serology for R. australis was present in four of five cases and a positive polymerase chain reaction (PCR) was seen in one of five cases. Histology showed varying features, from neutrophilic vasculitis to Sweet's syndrome and lymphocytic vasculitis. Recent significant advances in the diagnosis of R. australis infection include an eschar swab or biopsy PCR and isolation of specific Rickettsia on serology. These investigations should be considered in the presence of any of the following features: eschar at site of a tick bite or lymphadenopathy and fever with an eruption of erythematous papules and pustules.
