Kino: ePassport line for AUS, NZ, US passport holders. Free WiFi after log in. Ask for a free transfer shuttle voucher between Terminal 1 (International) & Terminal 2 (Domestic) for Virgin Australia fliers.
Kino: I highly recommend the Beef Brisket + Mushroom + Red Wine Meat Pie, Pork Sausage Fennel Roll, & Lamb Sausage Roll. The coffee is good too. Surry Hills is a nice neighborhood.
ELS Universal English College: Take a ferry ride from here! The ferry ride from Circular Quay across Sydney Harbour to Manly and back again is only $6.60 (this is called MyFerry2).
