There are over a thousand responses in our thread, so we can partially summarize. Why partially, because the research continues.
To date, my guess is that the first sleeper cab trucks in Australia could have been these two trucks. Late thirties Diamond T and REO
If you have different information connect to the research!

Friends, I apologize for the technical problems with logging into the link, the server is undergoing technical work. I have nothing to do with it, but I apologize for the inconvenience. Now the link is functioning!
Keep up the good work. You have a very interesting thread with many rare and unusual photographs. I know a lot of people like your work very much.
Thank you very much my friend. I'm glad you like it. I have accumulated even more new information over the years. But I am sure that you can find even more information in museums and libraries, especially for the twenties and thirties of the last century. But unfortunately I have no financial means to pay for the services of archivists. That's why the search is progressing slowly.

A French cute guy from the thirties, most likely a Renault. Thanks to the person who posted the photo on Facebook. Very rare photo, although there were many very interesting trucks in the thirties, but there are very few pictures of old trucks on the internet. There are a million pictures of Mercedes Actros truck and about fifty pictures of Mercedes L 10000. Most are interested in modern cars, which is a pity. And there is almost no interest to the truly valuable photos of trucks from the thirties. Modern journalism responds to the demand, which has nothing to do with history, and it's a pity. So I appeal to all history buffs who own photos of old trucks. Friends, popularize history, share pictures of old trucks!!!
