Hey,
Long time lurker, 1st time poster here.
I currently live in Caroline Springs in temporary accommodation whilst we look for a place to buy.
Nice quiet area, but would not recommend. As with most new suburbs in Melbourne, the infrastructure is awful. Yes they are building a train station, which should be completed in the next 12 months or so I believe, but it's a train station that you HAVE to drive to. i would rather live in a suburb where I could walk to the station. there are only 2 main road in and out of Caroline Springs, both of which are awful during rush hour. I work 10 minutes away in St Albans, it should take me 10 minutes anyway. it takes me at least 40 minutes on my commute.
Oh, I can't even get an internet connection at my place. Something to do with port availability at my local exchange. ridiculous.
Good luck!
