Anoraks go everywhere with marsupials (9)

I believe the answer is:

kangaroos

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

'marsupials' is the definition.
(I know this)

'anoraks go everywhere' is the wordplay.
'anoraks go' can be anagrammed to 'KANGAROOS'.
But, I am not clear how the anagram is indicated.

'with' acts as a link.

Can you help me to learn more?

(Another definition for kangaroos that I've seen is " Large leaping mammals".)

I've seen this clue in The Irish Times.
