As for Gwen Moore, I see she was last alive at 109 years. I will also remove her for now, unless other/new information pops up.

For Ada Sharp, I believe a birth certificate supports her claim of 28 Sept 1861. Not sure why she was validated with an earlier DOB.

As for others, do you have Mary Gwendoline "Gwen" Moore (née Lloyd) born in 1911? If you do have I will publish my list here so that we can come to a conclusion :-) 

Here we can see a chart which is showing us where 64 Australian sc's were born.

64? That's interesting, I've got 62 in my list. Which two do you have that I don't? (I don't have Ada Sharp, who was 109, nor do I have SCs whose 110th birthdays have gone unconfirmed.)

Obviously the 40 I have as native Australians can be broken up to those whose parents or grandparents were born outside Australia. 

@mendocino Actually all 3 men I have who has reached 109 from 1910 are Australian natives.

I know, but if you look at the ancestry of practically all Australian (super)centenarians, they have recent European ancestry, usually being either 2nd or 3rd generation immigrants. All four of Dexter Kruger's grandparents were born in Germany, for example. 

The last 2 charts I have created is for know Australian men who have reached at least the age of 109, for now I have included 14 men in my data.

The first chart is named "Australian men 109+ by decade". If my data is more or less correct, it is very exciting to see the 1910-decade already has smashed the record 1890's by already has 7 men aged 109+..We will most likely see at least 10 men from the 1910's decade turning 109+..

The 2nd chart is named "109-year old Australian men". This chart represent 10 various years.

Some main points to mention:

- If no mistakes, the years 1852, 1891, 1895, 1897, 1899, 1901 and 1905 has produce only 1 109-year old man each, this was smashed by the year 1910 who produce a record 3 men of 109+, including a new oldest Australian man ever.

- The current oldest man, Frank Mawer, who is 2 months away of his 110th is already the 8th oldest Australian man ever. 

I think it is fair to say that Australian centenarian men is slowly getting stronger, in fact, I don't think that Kruger's record will stand as long as Lockett's record did.

It's impressive how the 1910s have managed to produce nearly triple the amount of 109 year old men from the prior decade, despite being less than 3 years into this cohort. 

I'm not sure if immigration trends in the early 20th century can solely explain this increase, but it's definitely played a role. 

I plan to make more of this topics in the future and will upgrade my charts from time to time.
