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

'a great number' is the definition.
'thousand' can be an answer for 'number' (thousand is a kind of number). I am not certain of the 'a great' bit.

'shout out along with' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'along with' becomes 'and'.
'shout' anagrammed gives 'thous'.
'thous'+'and'='THOUSAND'

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