Hi there. Went through this a couple of weeks ago. Had our postal votes delivered yesterday as not sure where we will be on 21st.  Our Electorate is the last place we had a full time address. (That is what will remain on the roll unless we stay somewhere longer than a month in which case we then according to them have a perm address and have to register as such.) Besides the point.

We do have a PO Box - this is the POSTAL ADDRESS used for contacting in addition to email/phone. NO Mail goes anywhere near our old address. 

Let me know if you have any questions.

Another candidate for Mensa International.

According to my understanding of this article ...

... the Blue Ensign was the result of a competition held in 1900.

On 3 September 1901, the new Australian flag flew for the first time from the dome of the Royal Exhibition Building in Melbourne.[36] The names of the joint winners of the design competition were announced by Hersey, Countess of Hopetoun (the wife of the Governor-General, the 7th Earl of Hopetoun) and she unfurled the flag for the first time.[47] Since 1996 this date has been officially known as Australian National Flag Day.[48]

The competition-winning designs were submitted to the British Colonial Secretary in 1902. Prime Minister Edmund Barton announced in the Commonwealth Gazette that King Edward VII had officially approved the design as the flag of Australia on 11 February 1903.[1] The published version made all the stars in the Southern Cross seven-pointed apart from the smallest, and is the same as the current design except the six-pointed Commonwealth Star.[6]

On 4 December 1950, the Prime Minister Robert Menzies affirmed the Blue ensign as the National flag and in 1951 King George VI approved the Government's recommendation.[67]

When the Flags Bill was introduced into parliament on 20 November 1953, Menzies said:

"This bill is very largely a formal measure which puts into legislative form what has become almost the established practice in Australia ... The design adopted was submitted to His Majesty King Edward VII, and he was pleased to approve of it as the Australian flag in 1902. However, no legislative action has ever been taken to determine the precise form of the flag or the circumstances of its use, and this bill has been brought down to produce that result."[74]

This status was formalised on 14 February 1954, when Queen Elizabeth II gave Royal Assent to the Flags Act 1953, which had been passed two months earlier.

It was interesting to read that this flag invoked the resentment of republicans in 1900.

Alternatively the then republican magazine The Bulletin labelled it:

a staled réchauffé of the British flag, with no artistic virtue, no national significance... Minds move slowly: and Australia is still Britain's little boy. What more natural than that he should accept his father's cut-down garments, lacking the power to protest, and only dimly realising his will. That bastard flag is a true symbol of the bastard state of Australian opinion.
