Andy – in NSW the Residential Tenancies Act provides that tenants must be given at least one means to make rent payments that is free of fees other than for those directly charged by the bank or financial institutation involved (e.g. transaction fees).
So if your Property Manager / Rental Agent is merely passing-on those fees then that would be in compliance with the Act in my opinion, but if it’s some kind of in-house administrative or processing fee then they’d be in breach of the Act and liable for a max penalty of $1,100.
I’d suggest that you contact Tenants NSW who I’m sure will answer your query in a more definitive way.
