Revenue stamps of Western Australia

A year later special printings of postage stamps in lilac were similarly overprinted, but this time they were also surcharged with a new value.

These were replaced by a new set in a large format inscribed WESTERN AUSTRALIA INTERNAL REVENUE.

This design remained in use for many years, resulting in many reprints which led to various changes in perforation, watermark, colours and plates.

Colourless embossed duty stamps remained in use for many years, and in the 1960s similar imprints denominated in cents were used.

Cheques also had directly printed imprints instead of embossed or impressed stamps from the 1950s onwards.
