Actually $240 pw is standard share accom in that area. Anywhere near the airport is much more expensive than a little way out. You might want to look at Wooli Creek for close to the airport, you can walk to Int from there, no need to catch anything. And Wooli Creek is just one big housing estate so it wouldn't be hard for a few of you together and rent a nice new apartment there. They have some cafes but it's hardly a lifestyle suburb on the plus side it's on the rail line so you have easy access to anywhere else unlike Botany.
Expect to pay around $250pw for anything decent in share accom in Sydney. Kind of ironic when you can rent on your own for about $50 a week more...
