Only my opinion but...
I lived in Newquay (Nolan building) for 1 year. Location was great, I was working mostly in CBD, restaurants good to excellent (although you do get bored of the same ones eventually), bars great for a quiet (usually) or weekend drink. Wind shocking in winter. Newquay mostly faces south so balconies were cold. Good sizes, mostly 2/3 beds.
Lorimer St (over the other side), better finish, but not as good restaurants/shops (believe this has now changed but still not as good), larger developments, north facing, not as good location wise (but depends on where you work). Good sizes, mostly 2/3 beds.
Watergate and other mid developments (finish cheaper), prices cheaper though (obviously slightly different target market) and yes BC was cheaper because the facilities were not as good as Lorimer (anyone seen the swimming pool whilst driving past ?) or Newquay. Maybe a better location in a few years as closer to CBD. Smaller sizes, more 1 beds.
Victoria Dock looks like being the best location, waterfront, expensive prices, a larger range of apartments, don't know about finish yet.
Just to add, the apartment I lived in was advertised for $480, paid $410. Everyone I met that was renting was doing much the same. Although there is a surprising amount of older OO's in Docklands, must have sold up larger houses in 'burbs.
