I believe the answer is:

westerner

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

'types like a person from perth' is the definition.
I can't judge whether this definition defines the answer.

'we more serious' is the wordplay.
'more serious' becomes 'sterner' (stern can mean serious or strict).
'we'+'sterner'='WESTERNER'

Can you help me to learn more?

(Other definitions for westerner that I've seen before include "One from San Francisco, say" , "European or American" , "one from wild country?" , "Frenchman compared to Thai, say" , "Native" .)

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