For $10-15pw more ppl can get into a 3 br house. So its probably too expensive for people after a 2br townhouse.
Drop it down to 380pw then u can always increase rent by $10pw after 6 months. Every week that goes by you are losing far more money than a $15 decrease.
Rental market is quiet. Pye road is also not that desirable as its a bit busier than others and gets some M7 noise.
I just did a search and found what I believe is your place... it may also be priced too high, given other similar properties for 20-30pw less
