Sorry couldn't help but LOL. I've been there and I'd have to say no one in their right mind would choose CS over Berwick! My dads side lived in Melton we'd travel across the entire west watching it change over the last 30 years. The dead grass and windmills slowing being replaced with dust estates.
If you're family's grown up in Melbourne for more than 3 generations then you'd understand that entire area is prairylands and comparing it to Berwick is lol distance or not. I suppose sunshine and spotswood are the "Tooraks" of the west as well!!!
Even Sunshine/Maidstone/Braybrook and Footscray are heavily undesirable to people who know Melbourne. I think too many people lately are disregarding how undesirable these suburbs really are for the sake of a few train stations and food courts. I assume many people are looking to invest here are interstate using cbd proximity as a marker for quality, frankly there are no jewels in the west and comparing Caroline Springs
to Berwick let alone anything in the Casey region in terms of aesthetics and demographics is absurd. Berwick has strong demand for owner occupiers because if you're willing to put distance aside, it's far nicer than most suburbs between it and the city.
The west is for proximity everything else it lacks in comparison to all other regions of Melbourne!
