We went to Mt Hotham when DD was 18m old. We stayed in a lodge where you have your own bedroom & bathroom but shared living, cooking, games areas. It was fantastic and we had a great time. We drove there and we have our own gear. You can get packages where you buy lift tickets and gear all together. Depending on the kids ages there is daycare, ski school, kids concerts etc and also at the lodge they have pool tables, video rooms etc. If you wanted to spend more money there are helicopter flights, dog sled rides and that sort of thing.
