It's not just IH, but all the colleges in USyd are bloody expensive. A single room in drews, womens, sanctas and IH cost at least $410 per week. Compared to UNSW, where International House there costs $260+, Shalom $350...IH is ridiculously overpriced
I have no idea why USyd costs so much much to UNSW. Maybe inner city living is more expensive than living in the eastern suburbs.
