Some place at walking distance from Quakers Hill Train Station, and close to Quakers Hill Public School makes the most sense.
Best part of Quakers Hill will be closer to Quakers Hill Public School and Quakers Hill Train Station. Best of both the worlds.
Anything within 1km range of Quakers Hill Public School Catchment is SAFE, and best value for money in Quakers Hill - you get the BEST primary school (as per https://bettereducation.com.au/HotSuburb/primary/nsw/nsw_hot_suburb_rating.aspx) The Quakers Hill Train Station is at a walking distance, woolies/coles/aldi are 5 min. driving distance, Motorway/Parklea Markets/Stanhope Garden shops/Marsden Park Business Park are all 15 min driving distance - basically adding to daily conveniences of life...Quaker Road that has new house and land packages is getting rezoned to R3, and Quakers Hill Parkway (Cowper Circle side and the opposite side) are also getting rezoned to R4.
New side near Barnier public school/Farnham shops is good
People consider the nicer side to be the northern side (the side with the police station). I live on the 'nicer side'. However, I think both sides are great. The old side is 'older' but it isn't dangerous or rough. If you want a bigger block or are thinking about building a pool, subdividing or doing a knock down rebuild buy on the older side. If you want a newer, easier to maintain property which is closer to The Hills build on newer side.
Police Station or Northern side in my opinion is the best side. All trains have an inherent risk, Quakers Hill is no different to anywhere else. I would be considering my options at 2am in the morning
