I believe the answer is:

hippies

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

'flower people' is the definition.
(I've seen this before)

'in collingwood' is the wordplay.
'in' becomes 'hip' (both can mean fashionable).
'collingwood' becomes 'pies' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'hip'+'pies'='HIPPIES'

Can you help me to learn more?

(Another definition for hippies that I've seen is " Flower people".)

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