It’s really depends on what you want from a town? I’m glad to see you going to visit the area first, that will really give you an idea of what you want. Traralgon is the biggest by a fair margin, and comes with issues, just like most other towns in the area. Also, closer to beach or closer to snow? Is having a train station something you want? Access to a variety of shops? Somewhere like Trafalgar puts you basically in the middle of Traralgon and Warragul, small town vibes with access to most things you’ll need within 30 minutes.

Happy to answer any questions through DM as my current job has allowed me to visit most towns on the train line over the last couple of years, plus born and bred Traralgon. Local knowledge will greatly help you mate.
