Made in Australia. (Also in UK - see below). 

Miller [M] lists the three shown here. The third label L044 shows Vocalion (Foreign) Ltd., and Electrically recorded by Marconi Co.  Process. Vocalion was located in Mebourne. 

The first label US8-01 is an 8-inch, and were pressed between 1928 and 1930. Although physically smaller they were marketed as ‘the long playing record' as it had much finer grooves than the standard 10 inch, but in fact the duration was about the same. 

The second label L062, in the Delux Series,  was a 10-inch and with numbers W500 to W648 were, according to Miller [M], pressed from mid 1929 to mid 1930. (Then how come we one here at A1001.)

The third label, a "Broadcast" Twelve,  is a also a 10-inch, despite its name. It was proced in 1929-1930. 

The fourth label is a British Made 6-inch record, for children. It would take a brave DJ to play this over the air today. 

The Australian label, being pressed by Vocalion (Foreign) Ltd., was directly linked to the Broadcast twelve label in the UK, manufactured by Vocalion Gramophone Co. Ltd., of Hayes, Middlesex. They had a Broadcast Twelve, so I can assume with some confidence that the Australian Broadcast twelve simply took its name from the UK issues. The British Broadcast Twelve were devoted mainly to popular concer classics and drawing-room ballads, so it can be assumed that the Australian releases followed suit. There was also a Bristish Broadcast Super Twelve label but I have not seen this listed for Australia. 

Period: I can only quote the British periods, but again can assume that Australia followed suit. The initial broadcast lasted from July 1927 to Julky 1933. 

History: In early 1932 the Crystalate Gramophone Record Company took over Vocalion and all its labels, gradually phasing them out along with its own Imperial label, in favour of the Rex label.   

Reference: Miller [M], and Rust [R], who lists just the one British Broadcast Twelve label, but has text on the other varieties.
