My rates are a little more because of the land value.
The $280 waste mgmt fee is the price you pay for a large red rubbish bin. If you wish to move to the smaller bin - call council and let them know and you'll pay less (or they'll rebate you). Personally - while we're still buying furniture etc - I'm not brave enough to go for a small bin - we break up so much packing foam each week!
I have no idea what our site costs were - they were included in the package from the builder. You'll most likely need a H class slab though (not M class which is the standard inclusion most times).
It's 5% now, deferred 5% upon settlement for deposits.
