I presume you're talking about the 2 different campuses UNSW has in NSW - Kensington and Paddington.
Paddington's one is also known as the COFA campus, and is in a way much smaller than our Kensington one, but practically has most of the things you need - library, etc. Lol and because the campus is slightly smaller, you won't need to walk for like 20 minutes to get from one lecture to another.
