You need to leave the property “reasonably clean”. Consumer Affairs Victoria defines that as free of marks, dirt, cobwebs, stains and dust, where more cleaning wouldn’t improve it – measured against average community standards rather than a display home. Your property is compared against the entry condition report you signed, and you can’t be required to leave it cleaner than you found it.
Unfortunately, one landlord’s “reasonably clean” is another’s “below standard”, and that’s where an experienced Melbourne-based end-of-lease cleaner like Host Movers can help.
Note, this is a general guide to the Victorian rules rather than legal advice.
