I believe the answer is:

sun worshipper

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

'religious person' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'whispers pun or anagram' is the wordplay.
'anagram' is an anagram indicator.
'whispers'+'pun'+'or'='whisperspunor'
'whisperspunor' anagrammed gives 'SUN-WORSHIPPER'.

Can you help me to learn more?

(Other definitions for sun worshipper that I've seen before include "Tanner?" , "One who enjoys getting tanned" .)

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