Slogan - 100 Years ... Sydney

The 100 Years of Telegraph Service: 1854-1954 slogan was used in Adelaide from 5 April 1954 to 28 September 1954. It had been generally made available throughout Australia from 5 April although the 100 YEARS .. commemorative stamp was not issued until 7 April.

All five identified dies used at Adelaide with this slogan had ADELAIDE at the top and either:

a circular date stamp with no code number and either S. A. AUST. or SOUTH. AUST. at the base; or
a box date stamp with the number 4 at the sides or PAID at the base;

Within each of these broad types of dies, there are variations.

The date stamp usually had TIME then DAY/MONTH then YEAR.

The listing below is approximately chronological by base inscription and then Code number within that grouping. The following Table provides a guide with hyperlinks:

Shape and words at the base	Code number	Earliest date	Latest date	% of Adelaide Census
Circle - S.A. AUST.	None	5 April 1954	23 September 1954
