I believe the answer is:

anaglyph

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

'cameo' is the definition.
(thesaurus)

'a northern australian icon' is the wordplay.
'northern' becomes 'n' (abbreviation e.g. N. Ireland).
'australian' becomes 'A' (common abbreviation).
'icon' becomes 'glyph' (I can't explain this - if you can you should give a lot more credence to this answer).
'a'+'n'+'a'+'glyph'='ANAGLYPH'

'of' acts as a link.

Can you help me to learn more?

(Another definition for anaglyph that I've seen is " Stereoscopic photograph".)

I've seen this clue in The Independent.
