Well, our houses don't have bedrooms or bathrooms, for one thing.
Seriously, the only things you can really complain about for Adelaide are due to it being smallish and isolated.
Major events frequently don't come here - just the big cities of Sydney, Melbourne, often Brisbane, sometimes Perth to cover the West.
The population here is a little over a million, so there isn't the numbers to sustain a large nightclub or live music scene. Public transport is poor.
As a place to visit it isn't too much, except during "mad March" when all the festivals and events are on. As a place to live it is lovely. Clean(ish) air, mild weather (mostly), modest traffic, lots of parks and reserves, safe beaches, hills with gorges, and most of the facilities of a major city - we've even got a zoo with pandas, dammit.
