First day covers from Australia exist from the earliest issues, the hobby of philately had long since created a collecting interest for stamps used on the first day they were issued. First day covers before the mid 1930's were generally home produced, the individual usually writing 'first day cover' on their envelope.

Becoming increasingly available at this time were preprinted covers with an illustration or information relevant to the stamps that the individual could use to make up their own covers. The Australian Post Office also produced
generic 'official' first day envelopes (showing the Australia Post logo of Hermes in various designs and colours) which could be used for any first day issue.

Producers soon realised the popularity of these covers and started to offer services providing illustrated covers which they stamped and sent to the individual. There were various companies who offered these services, the biggest of which were
Wesley Cover Services (WCS) and
Royal. Other cover producers include
Art Craft, Excelsior, Guthrie and Parade. All these covers are very collectible, unaddressed covers fetching a premium.

Australia Post, obviously realising they were missing a market, started to produce there own
'Official' first day cover service in 1970. Covers were produced either addressed or unaddressed, again unaddressed covers fetch a premium. In 1980 they stared to use special cancels, on the stamp theme, which fetch a premium over 'ordinary' Po

st office cancels in this period, all covers were now unaddressed. In 1990 the special cancels became standard on unaddressed envelopes. First day covers are produced for all issues including for self-adhesive stamps and miniature sheets on cover.
