Mt Sheridan, Cairns - Good PM ?

We have a couple of properties in Mt Sheridan and the current property managers are basically losing interest (? too busy) and we are looking to move. Has anyone had any experience in the area and can they recommend a good agent?

I am not demanding but expect if I highlight a lagging rent problem that something might happen other than to be told 3 week later that they are now 4 weeks behind - but it's OK. (and then no follow-up)

Thanks in advance
