Pieces 1565 extra date

https://en.numista.com/catalogue/pieces1565.html

 The three 10 cent Australian coins are ...

KM#65 from 1966 - 1984
https://en.numista.com/catalogue/pieces1282.html

KM#81 from 1985 - 1998
https://en.numista.com/catalogue/pieces2561.html

KM#402 from 1999 - 2010
on the link at the top of this page. Except there is also a 1992 added at the start,
and the dates are locked so I cannot remove it.

I am not into Australia right now - someone else of the team is - hence the completed sheets.
However: I don't really understand what you noticed. what is 1565 extra date exactly?
what is missing or incorrect?

KM#402 is supposed to be only 1999 - 2010 but on the page it is shown as 1992 - 2010
 as there has been 1992 added in error (in my opinion) at the start of the date listings  -
 that year is already in the previous (earlier portrait) list for KM#81

 Rather than create a new thread I add this one here as it also has extra dates added in error, I think.
Different coin and country though; this is East Caribbean 25 cents 4th portrait.
 From the same country the Numista pages say the 4th portrait dates are ...
KM#35  2 cents 2002 - 2008
KM#36  5 cents 2002 - 2008
KM#37 10 cents 2002 - 2007
KM#38 25 cents 1986 - 2007 (should be 2002 - 2007)
KM#39  1 dollar 2002 - 2004
 For KM#38 the date errors are 1986 1989 as they are already in KM#14 2nd portrait.

 And this is the aforementioned KM#14 where the reverse lettering reads STATES not STATS

Thanks :)

KM#14 is ok. typo corrected
KM#38 is locked now and collections transferred. the reason for this error was that users could still
add years before 2007. now this won't happen anymore.
thanks

Australia 10 Cents problem should be solved now, too.
However, as I mentioned, Australia is not the list anytime soon. You might still find a lot of
errors and/or missing data. please be patient and thanks for all your help
