I was about to post in Aussie street-style but knew it'd get moved so, here I am. Some have already been mentioned...
- Orson & Blake on Riley Street, Surry Hills is one of my favourite stores; there's furniture and homewares upstairs, as well as a small gallery and cafe, and clothing, books and other knick-knacks downstairs. There's also an O&B in Woollahra that stocks a lot more clothing and homewares.
- Crown Street, Surry Hills is really great for second hand and vintage goodies. I love Cream On Crown 'cos I always manage to have fun in there.
There's also this fantastic antique store on the southern end of Crown Street that stocks beautiful French antiques. So chic! 
- Capital L on South Dowling Street, Darlinghurst is really nice and cosy and has a lot of nice pieces from Aussie designers. The girls there are really nice too (I mean that as in service).
- Glenmore Road in Paddington has a nice selection of stores. I think the Scanlan & Theodore store is right on the corner of Glenmore and Oxford. There's Parlour X, Ksubi, Kirrily Johnston, Paul & Joe and so many more that I can't think of right now.
- William Street, Paddington has probably got the best shops, in my opinion. There's Corner Shop, Belinda, Poepke, a lot of nice little vintage stores, Renya's also got another hair salon there... Oh and Just Williams Chocolates is so, so good. If anybody goes there, I recommend the hazelnut biscotti. It's the best thing in the world.
- The Westfield's complex at Bondi is also good for just about everything.
- David Jones on Elizabeth Street is another place to go, as well as Myer (which is in Sydney Central Plaza in the Pitt Street Mall complex). You can easily walk through to the Queen Victoria Building from here and The Strand Arcade (which has Akira, Corner Shop, Mimco, Gary Castles shoes, Jayson Brunsdon, Zimmermann, Third Millennium, Terry Biviano and so much more) is also located in the Pitt Street Mall complex.
- Martin Place is great; they've got the Prada store there, as well as the MLC Centre, which has stores like Robby Ingham, Belinda, Evelyn Miles (shoes), Salvatore Ferregamo, Longchamp, Gucci, Cartier, et cetera. Service at the MLC is really good, better than most places in Sydney. I have to say, I prefer the Robby Ingham store in Paddington (Oxford Street) but the ladies at the MLC store are really, really nice.
- The historic Rocks district is a really nice area; they've got tthe Galleria, which has Louis Vuitton, Burberry, Ralph Lauren, Dior, et cetera. There's a lot of art and craft stores hidden away here. I love the bead store in the Metcalfe Arcade, which is also home to the Rokit gallery (genuine vintage clothing and wares). The Rocks also have markets operating on the weekends.
- Glebe markets down at Glebe P.S. is really good. There's this guy that sells jewellery bits and pieces there, I told him I'd like to buy out his whole store. Surry Hills markets are also good and there's also the Bondi and Kirribilli markets.

Surry Hills markets are also good and there's also the Bondi and Kirribilli markets....
