All of my characters names feel right, bar one. What are some good white Aussie dad names? Mid 50s. Better if it's an Aussified nickname.

The character's name at the moment is Jacko, and he is the main character's dad. I think I chose it because it had an 'o' on the end, and because my parents had a friend called Jocko when I was a kid. But it's not quite resonating the same as the others.

So I'm hoping everyone will just throw names at me and one will feel right.

Also open to nicknames that are not proper names. Eg 'Bones'.
