If you look at the police crime statistics between Merriwa, Clarkson, Butler and Quinn's Rock Merriwa is the safest place to live. Merriwa was given a bad name many of years ago but in comparison to surrounding suburbs it is a whole lot better.
Merriwa is a fairly nice suburb. My brother lived there for some time and still owns property there. If you don't mind living so far from the city and on relatively small blocks. I expect an average 4x2 may be around $350-$400 per week to rent
