Dude.......start listing all the attractions, its not that hard is it?
I looked up a list of top 10 attractions in Adelaide, I'm seeing: train museums, an oval, a town hall. Thats my part of the "reasearch", so now I "know my shit".
Mate if theyre 'places of interest', Sydney has plenty of them. PLUS all the stuff that makes it a world renowned tourist attraction.
But I'm still interested to hear about all the touristy places that would interest overseas visitors you are talking about, cos you havent mentioned any yet, merely insulted me and called me ignorant.
I'm thinking....unique places, where people could take a photo and be like "WOW! You were in front of the Opera house!!"...."You were at the Eiffel Tower!"...."You were at the Empire State Building!"...."You were at the Adelaide State Librabry..."
