madoodi,
It doesn't give a number for the property, no, just leads a reader to believe it's somewhere close to PS's: a detective who goes out to "take a look at where the cameras could be installed" starts by parking on Benaroon Drive and walking through a property owned by "an old bloke called Paul, who is in his 70s" who "hadn't been on his usual morning walk yet".

So sounds like it could be #35, but the #144 Batar Creek Rd boundary is also very close to PS’ lot. Could be either, although given that PS found the camera on his walk and it looks as though he walks very close to the #144 Batar Creek boundary, it looks more likely that they were monitoring #144 Batar Creek JMO
