After transmission from the infected tick, the bacterium Rickettsia australias enters the body via the bloodstream. The first sign of disease is damage to the skin's microcirculation, which results in a rash. From there, the damage continues further into vital organs and can ultimately result in sepsis with multi-organ failure if left untreated.
