Approximarely 2% of the printing of both values was completed by the Government Printer, Sydney on a Heidelberg four-colour photo-litho press. It is believed all the stamps printed on this press were used for the souvenir stamp packs.

The other 98% were printed in Melbourne under the control of the Government Printer, by Norman J Field, on a Komori four-colour, photo-litho press. These stamps were used for general distribution to post offices and philatelic sales centres.

  • Silver – Process Magenta – Process Yellow –  Process Cyan (first pass) / Reflex Blue – Black – and a varnish (second pass) (18c)
  • Silver – Process Magenta – Process Yellow – Process Cyan (first pass) / Warm Red – Black – and a varnish (second pass) (45c)
