It Must have been.....

... 1958, when our family drove across the continent in our tiny-even-then Austin A30.  You don't see many of those around now, of course, even at car shows, but the A30 was quite advanced in its construction by dispensing with the previously traditional chassis & utilising a unibody or monocoque style of manufacture, which nowadays is pretty well the norm.
The engine wasn't very big at only 803c.c. but was very durable & enabled Dad to transport his family of 4 over 2000 miles from Perth to Melbourne. The roads weren't anything to write home about either (even if there had been Post Offices in the desert, which there weren't) being very rough limestoney gravel for over 1000 miles & along the Nullabor Plain.

Although that's not my mother in the photo, this picture  from the era seems to be have been taken in Australia, from the houses.
It might have been a stressful journey for Dad, with a wife & 2 teenage boys to manage as well as the terrible conditions. But I don't think it turned out that way & I recall singing Twilight Time each evening as the sun set. I think my singing must have been the most trying part of the journey, even though we had to carry both petrol & water for a couple of days as the settlements were so far apart.
But we made it without mishap, which is a credit to the planning & care that Dad &  Mum put into the venture.
