Yes mate, it is. The RTA actually states "over the specified amount" for when charging unlimited bond amount.
One call to DOCEP will confirm what they deem to be the "specified amount". Last time I checked it was $ 500 pw.....which 3/4 of Perth is probably now above.
I just had this very conversation with an agent who claims to be the coveted winner of the PM of the Year for 2010 here in WA, and she said it was 4 weeks ?? I said no way, she did some digging and came back and apologised. We are now charging 6 weeks bond, plus 2 weeks in advance.
Sometimes you just need to read very carefully. Most don't.
