From the Vicroads exemption form:
"What is a family type vehicle?
A family type vehicle is typically a sedan, station wagon
or hatch used to carry families with 4 or more seats and
when manufactured was equipped with child restraint
anchorages. A family type vehicle does not include
sports cars (eg a two door coupe) or the sports oriented
variant of a specific model range."
So to those asking whether you can get an exemption for cars such as a Territory Turbo, Golf GTI etc, you can't.
Too many people try to evade the law based on technicalities, and a lot of the time it doesn't work, especially with subordinate authorities who base their whole organisation around transport. I think people are forgetting that Vicroad's is not part of the government itself, they are a specialised organisation who base their existence upon transport, and for that reason know the in's and out's of it, unlike politicians, who try to know everything, about everything, and a lot of the time, do not.
