Landlord claiming bond for cleaning without invoice - what are my options?

I recently vacated a rental in NSW and the landlord is seeking to retain part of the bond for cleaning.

The property was cleaned to a reasonable standard and is consistent with the entry condition report, allowing for fair wear and tear.

So far, they haven’t provided an itemised invoice or receipt, just a general claim.

Am I entitled to request evidence of actual costs before agreeing to any deduction?
