An outgoing woman crazy for marsupials (7)

I believe the answer is:

wombats

'marsupials' is the definition.
(wombat is a kind of marsupial)

'an outgoing woman crazy' is the wordplay.
'outgoing' suggests deleting specific letters (some letters go out).
'crazy' becomes 'bats' (bats can informally mean crazy).
'woman' with 'an' removed is 'wom'.
'wom'+'bats'='WOMBATS'

'for' is the link.

I've seen this clue in The Guardian.
