That would have been a hell of a drive Dugrene
In my early 20's (a couple decades ago - 80's) I moved to Melb for a new job and did the drive solo Perth to Melbourne on Fri-Sunday in 26.5 hrs driving time. Got away late morning on Friday and had a sleeping stop first night at Border Village motel (SA side of Eucla), but was flipping dangerous (and flipping stupid) driving through most the second night going through east SA and Vic. Road's a lot better now. It's a hell of a long way, nearly 3,500km I think. The speeding fines cost quite a bit more than the fuel did- cops much worse/more prolific on Vic side.
Have also done it with a couple of other drivers and with 3 non-stop is easy with 1 rsleeping on back seat.
If I did that drive solo again would suggest the same for first day but then stop maybe Bordertown on the SA/Vic border for next night and you'd still get into Melb by midday. Or take an extra day and checkout some of the sights (eg. Eucla cliffs/caves as well as Spencer Gulf).
Left Perth about 5pm Tuesday crossed the Nullabor and at Ceduna sometime Wednesday arvo slept somewhere for a couple of hours. went through Adelaide about midnight wednesday and arrived where she lived directly across from Kensington train station about 7.30 Thursday.
I was a long time ago and didn't think anything of it at the time. Mind you I lived in the Pannawonica or Wickham and would drive overnight to perth often. From Panna in 13 hours from Wickham 15.5. Had a steel roo bar and used to sit on about 125k.
Being a train driver I was conditioned i guess.
