It is most fitting that this superb series came at the end of the recess-printed era, and showed off the finest of that printing technique.
The navigator issues replaced the equally attractive Arms format designs for Australia's higher postage needs and continued, as a series, into the decimal era. As was the policy of the time, all values 5 shillings and above, appeared on watermarked paper. So, in this issue of definitives, only the 4/- value is unwatermarked.
Similarly, specimen overprints were supplied on values above 5 shillings. Making the 4/- and 5/- values the only denominations cancelled CTO.
The unusual quantities stated for each denomination is a result of this issue being withdrawn from sale at Decimal Currency.
All values were designed by W. Jardine . The individual engravers are listed for each denomination.

The somewhat confusing issue of papers is illustrated above and should have some clarity.
The navigator series was not issued simultaneously. Instead, they were dribbled out beginning with the 4/- in October 1963 and ended with a late replacement for the 5/- cattle definitive in November 1964. White paper was introduced to the note printing branch in mid 1964, and subsequently, the early values of 4/-, 10/-, and 1 pound are on the old cream paper, whereas the later releases are on white paper.
In the specific case of the 10/- and 1 pound values, fresh print runs were required after the introduction of white paper. Consequently, they are found with both papers.
*The 5/- cattle was a definitive in it's own right and in heavy demand. It is not surprising therefore that it too is found with white paper as it also underwent many print-runs.
Layout: Stamps used the 480 on medium format, or the 320 on Long Format.
