The Australian Philco is a bit of a puzzle but I'll attempt to solve some of it.
The picture refers to a model 203A made in 1948. The references I have don't list the model 203A and the tubes used limit the set to a specific period. The IF transformers are typical of components made by Philips during the 1950's and 60's and at a guess I believe the set was made by Philco Australia using local components and possibly using an imported case.
The nearest set (based on tube types) I can find are the 1952 models using metal base octal tubes (loctals are extremely unusual in Australian radios). An example would be the F103 using the following tubes: 6SA7GT (converter), 6SK7GT (IF), 6SQ7GT (detector/audio), 6V6GT (audio Output) and 6X5GT (rectifier).
The tube line up is a typical 5 tube arrangement of the period however the types used were not in use for long as the all glass 7 and 9 pin tubes were becoming more popular in the early fifties.
Live chassis sets were made and sold in Australia and were called AC/DC models. They tend to not be so common as by the early 1950's 240v DC mains had been mostly phased out. The need for special (costly) tubes and other parts to make 240v series heater strings meant it was more economical to use a transformer.
