Some insurance companys will not insure you if they view you to be living in "shared accomodation". I know you guys arent but be prepared if the silly person on the phone deems you to be.
RACQ might be different though, I know RACV are one in Vic who will insure without asking discrimatory questions.

If you log on to one of their websites, there is often questionairees on their and even contents estimators tools, that go through room by room to help you put a proper value on your contents.

Clothing is one that people often understimate. I know someone whos house was cleaned out - they cam home and everything was gone, someone had just got a removalist can and taken everything. What they didnt take, were the hangers in the wardrobe. And the insurers based their clothing estimate on the number of hangers in there - so now I always have lots of spares.

Also remmeber you need to insure for how much it will cost to replace the item - which could be more than what you paid.
