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

'eco-safe' is the definition.
I can't judge whether this defines the answer.

'plastic refined in australia exclusively' is the wordplay.
'plastic' is an anagram indicator (plastic can mean easily moulded).
'in' means one lot of letters goes inside another.
'australia' becomes 'oz' (informal name for Australia).
'exclusively' becomes 'only' (synonyms).
'refined' anagrammed gives 'efriend'.
'oz'+'only'='ozonly'
'efriend' put into 'ozonly' is 'OZONE-FRIENDLY'.

(Another definition for ozone-friendly that I've seen is " (Of aerosols) green".)
