Just make a quick phone call to these guys and you'll know for sure..
tenantsqld.org.au/need-advice/For example I have been to houses where they have been tenanted for a decade. The house is clean, there is no damage. The owner comes in and changes carpet, paints the house, changes a few door handles. There is no expectation for the tenant to pay for this as any reasonable person would see it as maintenance that would be required to be done by the owner every 5-8 years.
The Landlord sounds like he'll complain about something anyway. Give him something big to complain about and he will probably overlook the numerous trivial stuff that he would otherwise complain about.
Ideally, let him get his knickers in a twist about the scratches on the floor, he can take heeps of photos and try and make you pay for 'damages'.
After he sends you an Invoice for $2000 on top of keeping all your Bond to polish his floor, you can write a nice letter back explaining 'fair wear and tear'. Explain that you have paid rent to live in the house and it should be of no surprise to any reasonable person that the once new floors will not look new after 2 years of use.
