The Australian National Insect Collection (a section of the Entomology Division of the CSIRO) has digitised its collection records. These can be searched through their portal.
Go to the ANIC search site and fill in the appropriate tab sections.
Results are returned in a new tab and/or a 'pop-up' window so you must have enabled 'pop-ups' in your browser to actually see anything!
Links on specimen data can be used to drill down for further details.
This is a 'work in progress' and sometimes queries don't do what you expect, persevere.
Sometimes maps 'stick' on previous searches ... persevere
