From country itself (1992): indigenous in Queensland. Area freedom in New South Wales, Victoria; does not occur in Tasmania, South Australia or Western Australia (eradicated from Western Australia in 1992); may hybridize with B. aquilonis in Northern Territory. An outbreak in Adelaide (South Australia) in 1993-02 was eradicated by the Sterile Insect Technique.

First reported in the Sydney region in the late 1800s. Established in central Queensland and New South Wales, as well as in Alice Springs and Darwin. Sporadic outbreaks occur in Victoria and South Australia. A single outbreak was detected in 1989 in Perth (Western Australia) and was successfuly eradicated. The species status of B. aquilonis (possibly part of B. tryoni) is still debated, but this species occurs in Northern Territory and northern part of Western Australia (Clarke et al., 2011).
