The Great Alpine Road runs through the middle of the resort in fact, there's a point on the Sun Run where you can ski over a road bridge. Most runs or lifts to them leave at an easily accessed point on the road. However, parking near the center of the resort is difficult to get, and you may need to park at the edges and catch the free bus to the run of your choice. Be careful of pedestrians: people catching the bus up and down the resort frequently have to cross the road on foot with armfuls of gear, and there are no marked crossings. The usual practice is to give way to any pedestrians.
The village bus service is operated by a set of clunky old school buses with big SNOW BUS labels. This free bus service drives up and down the length of the Great Alpine Road inside the resort. Catch it at any of the "Village Bus" bus stop signs which are located near most carparks and major lifts and run end-points on the road. It arrives every 5-10 minutes. Skis must be stored in the holders on the outside of the bus, but snowboards are carried on board. Be careful when waiting for the bus, particularly if waiting on the side of the road that has a drop-off. There are no fences or safety rails protecting you from walking off the edge, although obviously the bus doesn't park right next to it it also doesn't stop far away from it.
