One who wrote Australian God of Thunder (6)

I believe the answer is:

author

I'm a little stuck... Click here to teach me more about this clue!

'one who wrote' is the definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.

'australian god of thunder' is the wordplay.
'australian' becomes 'au'.
'god of thunder' becomes 'thor' (Norse god of thunder).
'au'+'thor'='AUTHOR'

Can you help me to learn more?

(Other definitions for author that I've seen before include "Write" , "Ours wrote as Edward" , "One writes" , "Writer of a book, say" , "Creator of written work" .)

I've seen this clue in the Sydney Morning Herald.
