Shouldn't be any confusion - the road is either gazetted or it isn't.
The relevant Lands Department will have the record.
Travelling stock routes and roads to water reserves are another issue - probably best checked with the local Shire office or PP Board.
We had gazetted but unused "roads" through two of our properties in NSW which were left to us to maintain 100% - sorry to have to say it, but damage from 4WDS and trail bikes, weekend shooters etc were a genuine pain.
Cheers,
