I agree, Sydney Westfield is great. I also love Bondi Junction, it's big and shining, like many of its stores. I always feel just that little bit more "high-class" when I shop there, the variety of stores is extensive, and there's great restaurants as well.
I'd have to say Westfield Sydney. Six floors of chocolate, fun and fashion all under the one roof. It was worth the wait. Otherwise for factory outlet quality goods, you can't go past Birkenhead Point.
Agreeably Westfield Bondi Junction is the best shopping district in my eyes in the inner suburbs of Sydney. With enough swish and space to fit a large fancy army, the place has literally almost every store you will need in the one destination. However, if your after somewhere with such a large range of stores but more cheaper prices Westfields Parramatta is your place. It is a bit of a trek from the City but is surely worth it if your after some retail therapy less damaging to your wallet.
I've always liked Castle Towers and Rouse Hill town centre. Great variety and location. If you're up for abit of a drive, Warringah Mall and Westfield Chatswood are great too! Westfield Miranda in The Shire is undergoing a massive overhaul but is set to be on par with Bondi Junction.
Gbrow, I'm sure the Apple shop & Nespresso went in there because my husband & I asked them to have a shop there, So much easier then going all the way into the city for their service! We get a free coffee overtime we're down there, so who needs to use a cafe?
