just took alook at the Aussie names sight.
Never ever name your chickens after the first word on there. Thats would be the same as if you called african american a rude word.
Billabong- No one ever uses that word except in Waltzing matilda lol
Cheerio is English not Aussie.
Kiah- Never heard of...
I have a coronation sussex male named Charles cause he looks regal then my son decided to name his three girls the angels. So that ruined the regalness behind it lol.
