Leadsled,
Albion Park Greyhounds is actually in Brisbane; I think you are referring to the Dapto greyhounds, universally know as the "Dapto Dogs". The airport isn't in Dapto, either. The nearest suburb is Albion Park Rail.
On a more serious note, think of the total cost of all the upgrades to GPS databases, IATA publications, Airservices charts and so forth which such a change automatically requires. Apparently the mayor of Shellharbour wanted the change, and I'm not aware of any consulation with airport operators or businesses. As for making an already congested CTAF just a little harder to work with, I couldn't agree more.
