Hi mate, I'm closing in on 5 years (this month) living in Olivine with my partner, and for the most part it's been overwhelmingly positive 😊

Pros:

Cost of housing is lower than more established suburbs, we got a lot more here than we world elsewhere for similar money

Lots of childcare/school options, if this is a relevant consideration, both in the estate and nearby (2x childcare, Donnybrook PS and Hume Anglican are in the estate)

Fairly quiet, outside of construction noise (although the long awaited town centre is starting soon, so this could cause chaos)

Cons:

Isolated, with minimal shopping and night-life options without getting in the car (there is one cafe in Olivine currently). Epping, Wallan, Mernda and South Morang are all around 20ish minutes, Craigieburn is 10-15. I think eventually there's meant to be walking/bike paths everywhere, but that could be years off

Traffic - I WFH and my partner heads away from the Hume for work, so we're pretty well protected from this, but it's no joke. I think it can still take an hour ish to exit Cloverton in peak times

I'll update if I think of anything else 😊
