Samsung took nearly 6 months to start offering official accessories on their Australian website for the Galaxy Nexus and even then they only offered the HDMI Dock, but it now looks like Samsung is offering some accessories for the Galaxy S III on their website. You can get :

Galaxy S III Desktop Dock : $49.95
Galaxy S III C Pen Stylus : $29.95
Galaxy S III HDTV Adaptor : $39.95
Galaxy S III Flip Cover : $34.95 (Available in Blue or White)

Shipping is extra so take that into account, also when trying to purchase any of the accessories you’ll be advised that Samsung is expecting stock on hand on the 15/06/2012 so hopefully if you order tonight your order will ship tomorrow. no sign of any desktop or car docks, spare batteries, cases, S-Pebble or the wireless charging adaptor which is said to not be available till September.

Personally, I think this is a good sign that Samsung is learning, getting the Galaxy S III out to most markets fairly quickly after the initial announcement and following up with accessories as well is a great sign, now if they can just keep it up for any future launches they have. Anyone looking to purchase some accessories for their new Galaxy S III?

Edit : Looks like Samsung has a Car Navigation kit for the Galaxy S III on their accessory site as well but haven`t associated it so it doesn’t appear when you click the Accessories link from the Galaxy S III description page. The Navigation kit will set you back $39.95 + Postage and according to the description page it is ‘Adjustable cradle functionality (4.0 ~ 5.3″) allows fitting of most hard shell cases and silicon skins’ so from the sound of it, this will fit pretty much any of the Galaxy Phones up to and including the Galaxy S II, Galaxy Nexus, Galaxy Note, Nexus S and of course the Galaxy S III.
