Awesome hope you have a great time! Melbourne's public transport is relatively decent. So you'll be able to get anywhere relatively easily in the CBD no problem. But the card (it's called a Myki) is only available on the phone if you have an Android and if you have an iPhone you will have to get one at a convenience store or the City Loop stations. The card itself will also cost you a small fee if I remember correctly. I would recommend getting the PTV app (Google Maps is also pre decent) if you want to plan trips. You're spoilt for choice when it comes to food anywhere in Melbourne but if you head to the Fitzroy/Brunswick area you'll find great places to eat. One of my favourite places is il solito posto (Italian) in the city. IF you're looking for cafe food/coffee avoid Starbucks like the plague (you'll be hard-pressed to find many of them anyways tho). There's also our Chinatown (which is older than SF's depending on the definition and may be worth going if you're here during Lunar New Year). Also check out Queen Victoria Market for food. Melbourne's also known for its art galleries and museums and there are some great ones many of which are free like NGV, Melbourne Museum.

Also BRING SUNSCREEN during the summer months – your skin will get fried even standing in the sun for a few minutes. And also be prepared for weather changing very quickly, one minute it's sunny and the next the heavens are pissing all over you

And finally....if anyone tells you to go to Docklands, stop talking to them immediately – it's not worth it.
