Isuzu is my guess? They might be tied to https://whg-telematics.com.au (my guess at the redacted URL if it is even partially real in the post).
Isuzu doesn't really sell passenger cars in Australia, only trucks, pickups, and for some reason a single SUV (MU-X) I'd never heard of before looking this up just now.
Up until recently most Isuzus were sold as Holdens. They don't sell passenger cars here because they don't make much of them anymore. At least for export.
The Holden Piazza, Holden Gemini, Holden Rodeo and Holden Jackaroo were all Isuzus. The rodeo and jackaroo were the earlier incarnations of the Ute and SUV they sell now directly as Isuzus.
Also, fun fact, years ago Isuzu sold the Isuzu MU Wizard. MU is an abbreviation. The full name is Isuzu Mysterious Utility Wizard which has to be the best name for a car of all time.
