Suburbs in Perth (Greater), Western Australia | realestate.com.au local voices
You'll find housing and renting in Perth expensive, and the market a lot tighter than any Eastern States city. The only place equal to Perth for excessive pricing for housing and accommodation is Darwin.
Steer clear of Armadale, Gosnells, Thornlie, Lockridge, Koongamia, Koondoola, Ballajura, Girawheen and Nollamara, unles you want to be a victim of regular crime.
Ask any policeman or policewoman what their "hot" suburbs are, and you'll soon find out the suburbs to steer clear of.
The suburbs above are plagued by car-theft, bag snatching, and robbery by a small number, but a very nasty variety, of the indigenes, who are the main cause of crime in Perth.
A favorite stunt of theirs is to cruise the suburbs in a stolen car, find a fast set of wheels (hot Commodores are a favorite) - whereby they break into the house and steal the keys, usually bashing the victim/s in the process. As a result, hot wheels are best kept hidden from street view.
Be very careful trying to apprehend these people, if you look like becoming a victim - they work in groups and a couple are usually hiding, so that they can belt you from behind, when you're trying to stop your car being pinched. They also nearly always carry screwdrivers, and commonly use them to stab victims.
A mate who is a 190cm (6' 4") rugby full forward, tried to tackle two of these thugs at 2:00AM, when they were in the process of stealing his wifes Beemer.
He had two black heads by the hair, and was just at the point of banging them together, when he was laid out cold with a big lump of timber, by another thug hiding in the bushes behind him.
They got away with the Beemer, and he spent a couple of days in hospital with severe concussion and gained a substantial number of stitches in his scalp.
