um...if you take the free uni one, that is the only bus that will take you to the uni now anyway...it takes about 2-3 minutes, depends on traffic lik ehte traffic lights but about that much. No, i mean it takes about 5-7 minutes to werrington, about 2-3 for kingswood campus.
Here is the route: kingswood gate[1st stop], goes inside kingswood through to werrington south [2nd stop] at the building then the library building [3rd stop] which is where you want to stop to go to building BB since its more closer, than onto Wrrington North then back through south at the same stops than kingswood building K and Kinsgwood station.
Campbelltown: well of my experience, i alway get a campbelltown train and not a macarthur becasue its rare or im late. But i get to campbelltown sations and you can go to macarthur via the uni shuttle or the cityrail bus. to use the cityrail bus [IMO better becasue less people and a bigger bus than the shuttlr] all oyu have to do is have a ticket that goes to macarthur. the bus is on the same side as the platoform you get off at, jsut ask the cityrail guy.
when you get to macarthur station, you have to walk over the overpass bridge thingy, just follow some of the people if you see them walking up stell steps. and just go through to over the other side and you will see the campus far away, about a 5-10 min walk.
