Parking space capacity

I own an apartment in a luxury high-rise in the Parramatta CBD. My apartment came with car spaces that consisted of 2 adjacent “disabled” (extra wide) spaces. This capacity was pivotal in choosing the apartment I purchased over a similar apartment.  Some months ago the OC decided to remove the disabled signage as it was no longer required. The spaces are on title to my apartment and are delineated by painted lines. Adjoining the spaces on one side is a storage cage that is also on title to my apartment. There is no right of access over the spaces and no other common property adjacent, other than walls. We own 2 cars. There is no visitor parking in the building and virtually none in the surrounding streets. When we have visitors we park 3 cars in our space as they fit comfortably without encroaching on any other space or on common property. The OC in our building can be very “active” about the parking area and have pursued owners who park boats or trailers or anything but cars or motor bikes in their spaces. Are we entitled to use our space for 3 cars?  What issues are in play here?
