I was very pleased to come across Palmers Interstate express service in this forum. On 25th & 26th of March ,1947 I travelled from Stratford, Vic. to Sydney in JB666, the sideloader bus pictured. I have a better photo of this vehicle taken on the ferry at Batemans Bay being before a bridge was built there.
George Palmer received a lot of publicity in Gippsland during the early post-war years.He was determined to get the interstate passenger service going against strong government opposition. Railways were almost sacred then, in fact the Transport Regulation Board who issued transport licences was colloqually called the " railways protection board!" George Palmer was a persistant lobbyist. Initially he was only permitted to run between the railheads at Bairnsdale and the most southern coastal railhead in NSW. I don't remember where that was. In order to provide a reliable timetable and reach the overnigh stop at a reasonable hour he convinced Nsw authorities to allow him to run through to Sydney but had much more trouble convincing Victorian government.
When I travelled he was only licenced to run from Traralgon to Sydney. Frequent late trains effected his timetable so much that eventually hi licence was extended to Melbourne. Sydney was the terminus when I travelled. Obviously Brisbane came later.
In 1947 the Princes Highgway was bitumen from Melbourne to Brodribb River past Orbost ,then apart from some sealed roads in towns was grave or dirt surface to Batemans Bay.In many parts in East Gippsland and Southern NSW the road was only sigle lane. From memory the bus left Traralgon about 1PM and reached .Genoa Hotel for dinner about 7PM, then continued to overnight stop at Eden. After early breakfast next day trip continued reaching Sydney sbout 7PM. Consequently several hours of night travel was involved on the most primative parts of the road. The driver said he preferred thi as it was easier to see headlights coming through the bush at night than a car in daylight!. I just realised that JB666 was probably the first bus I ever saw with kangaroo bars fitted.
I will endeavour to download my photo. The bus looked much newer then.
