The flag of the Commonwealth Lighthouse Service was the Australian national flag with a lighthouse badge in the middle of the southern cross.

This flag was in existence since before World War II, but is no longer in use.

On the Lighthouses of Australia website there are photos of two historical ensigns of the Commonwealth Lighthouse Service (Australia). The images at the top of this page is made to match the photos. It is not clear which flag of the two was the older ensign, but both are apparently no longer used.

About all that is known of these Commonwealth Lighthouse Service flags are the details listed below. Unlike the Customs flags and Quarantine ensign which were constituted in legislation, nothing to do with the flags has been found in the Lighthouses Act 1911 nor the Regulations, both now repealed. The expanded Southern Cross was apparently based upon some inaccurate, government-sourced colour plates of the Australian Blue Ensign and Australian Red Ensign that appeared in publications such as the Admiralty Flag Books of 1910 to 1930 and the Commonwealth Statutory Rules books of 1914 and 1927. This allowed the oval lighthouse badge to be placed in the true fly centre. However it would appear that when the Flags Act 1953 took effect and precisely laid out the design of the Southern Cross in legislative form, that the blue flag was abandoned in favour of the undefaced Australian National Flag and the red flag adopted the standard Southern Cross with the oval badge fitted within it as best as could be managed. Later this flag was replaced by an Australian Red Ensign with a new round badge placed in the flag's lower centre.

Digitised files in the Australian National Archives show that:

1. A flag for ships of the Commonwealth Lighthouse Service was authorised in 1915.
Governor-General Despatch No.322 of 14 December 1914, and Colonial Office reply of 2 March 1915.
[barcode 420414 (pages 6 &7)]

2. In 1954 the department of Shipping & Transport’s tender ‘Wallach’ in Papua/New Guinea flew the Australian Red Ensign defaced with a Departmental Badge. Papua & New Guinea Administrator to Department of Territories, Canberra [102516, page 44]

3. In the same year the department was shown to have two flags; a National Flag defaced by a lighthouse for Lightstations, and a Red Ensign defaced by a lighthouse for Steamers in the lighthouse service.
Table of flags in a Memorandum of 22 December 1954 [7853923 (pages 44-46)]

4. The Departmental Blue Ensign was flown at lightstations until about 1955 when it was replaced by the Australian National Flag following the 1953 Flags Act and the decision that the Australian National Flag should not be defaced. 28 April 1956, South Australia Minute that “Blue Ensign, not defaced, to be supplied to Althorpe.” [1054691, page 2]

5. A constructional drawing of the defaced Australian Red Ensign <au~clsre.gif> and detailed drawing of its badge are dated 2 October 1962. [1716297; 1716298]

It seems likely that the flag authorised in 1915 was an Australian Red Ensign with probably the same badge as the Australian Blue Ensign (flag at top of this page) that was later authorised (or merely taken into use) for lightstations, and that it was replaced by (second flag on this page) in 1962/3.

Jos Poels has pointed out a photograph of a Lighthouse Service Red Ensign in Australian National Archives file 11449759. The caption is ‘A crewmember of the lighthouse supply vessel Cape Don repairs ensign 1963’.

The centres of the CLS flag's Southern Cross stars varied by the following measurements from the specified positions of the stars on a 72-inch wide Australian Blue Ensign;

Alpha Star was two inches lower,
Beta Star was four & a half inches further towards the hoist,
Gamma Star was two inches higher,
Delta Star was seven & a half inches further towards the fly outer edge,
Epsilon Star was eight & four-fifths inches further towards the fly outer edge.

Epsilon on the CLS flag sat the same distance from the fly centre line as Delta on the standard Australian Blue Ensign. Vertical heights of Beta, Delta and Epsilon were the same as the Australian Blue Ensign. On a 72-inch wide CLS flag, the oval lighthouse badge was 20 inches wide by 25.75 inches high.

The 1963 photos of an oval-badged Australian Red Ensign under repair by Mr J Dick aboard MV Cape Don appear to show a normal ARE with a reduced-size oval lighthouse badge placed within the standard Southern Cross and offset slightly towards the hoist.

The disc-badge version of the CLS Red Ensign appeared from circa 1962, and placed the new badge in the flag's lower centre. This badge was one-third the width of the flag and the colours were; yellow outer ring, medium-grey rock, white lighthouse, window and light beams, scarlet above the white lighthouse collar, and imperial blue sky. No blue version of this flag is known to have existed.

These flags were removed from service circa 1973 and replaced by the Australian National Flag as the ensign of the lighthouse tenders. The Commonwealth Lighthouse Service ceased operations in the 1990s.
