Introduction

In 1832 John Nicholson, then harbourmaster of Port Jackson (now better known as Sydney Harbour), published the 'Code of Signals for the Colony of New South Wales". The Nicholson Flag Chart consists of Marryat's Signals, with 16 flags each for the Royal Navy and the Merchant Service, plus the Colonial Signals, with 18 Descriptive Flags, 12 'Colonial Numerals for Pilots Reports &c.', and 12 'Proposed Miscellaneous Flags for N.S.Wales and the South Seas' (mostly ensigns). Also included on the chart are five examples on how the signals would be displayed to convey messages: the Descriptive Flags would be flown either on their own, or with the Numeral Flags underneath which indicated the origins of individual ships according to a pre-determined code list.

The Colonial Signals were in use until circa 1940. By then the Descriptive Flags had four more flags added; the Colonial Numerals became the Garden Island Weather Signals to indicate wind speeds, with the Numeral Flags indicating a corresponding Beaufort Scale.

The old Colonial Signals have been partially revived since 2008, when a flagstaff was re-erected on Observatory Hill in Sydney, on which signals flags had been flown from circa 1810 until the late 1930s. Among the other flags flown on the flagstaff nowadays are some of the Descriptive Flags, as well as the Colonial Numerals flown to indicate the day's maximum temperature in Celsius.

The Signal Flags

The following nomenclature was dated circa 1940.

0 - Calm - less than 1 mph

I'm not sure a flag signal to indicate there was no wind would be very effective. But I understand the flags are just a numeric code, with the 0 being used for "10" as well.

Numeral pennant

Same as the Numeral Pennant on the original Marryat's Signals. The Nicholson Flag Chart showed this pennant as being narrower than the other Numeral Flags.

As used in the Numeral 11 flag.

Temperature

This is a modern (since 2008) flag, with a darker shade of red than the original signal flags, to be flown above the Numeral Flags to indicate the day's maximum temperature in Celsius.

The Description Flags first appeared on the Nicholson Flag Chart of 1832.

Proposed Miscellaneous Flags

The Nicholson Flag Chart of 1832 illustrated a dozen "Proposed Miscellaneous Flags" in four rows. Of particular interest is the third row, featuring the purported flags for three island groups in the Pacific, which are illustrated below.

First row:
Blue Ensign
Red Ensign
Blue Peter
Second row:
NSW Ensign
NSW Merchant (similar to the NSW Ensign but with two additional horizontal blue stripes)
Sydney
Third row:
Polynesia
New Zealand
Sandwich Isles (i.e. Hawaii)
Last row:
Custom House
Pilots (White-over-red bicolour)
Post Office Packet (similar tohttp://collections.rmg.co.uk/collections/objects/206394.html but with a white field)
