Something swept up in Victorian loo bust, sadly (4,5)

I believe the answer is:

dust bunny

'something swept up' is the definition.
(a dust bunny is a ball of dust)

'in victorian loo bust sadly' is the wordplay.
'in' is an insertion indicator.
'victorian loo' becomes 'dunny' (Australian slang - Victoria is an Australian state).
'sadly' indicates anagramming the letters.
'bust' anagrammed gives 'stbu'.
'dunny' enclosing 'stbu' is 'DUST BUNNY'.

I've seen this clue in The Times.
