The Central Coast is gorgeous. We live in Avoca which is a beach suburb. I don't know Lisarow it is more inland (but saying that only about a 20 minute drive for me). When I have driven through it, it appears more to be more acreage properties but as I said I don't know the area. If you are on Facebook, there's a great "Central Coast Expats" group. You may get some more info from there.
If you moved here, you would not be sorry especially if you have young children.
Sydney is an hour and half train journey away. Great on a Sunday as only costs $10 for a family of 4 ;-)
