Australia’s oldest tertiary institution (1850) has over 49,000 students and even boasts its own postcode. You don’t need to have a PhD to grab a free campus map and wander around. Flanked by two grand halls that wouldn’t be out of place in Harry Potter’s beloved Hogwarts, the Quadrangle has a Gothic Revival design that tips its mortarboard towards the stately colleges of Oxford. It's well worth seeking out the august collections of the Nicholson Museum , University Art Gallery and Macleay Museum .
