Parking in a resident parking space

Ok i’ve looked through the forums and i could find anything that applied to my situation, despite parking being a big issue almost everywhere. Here is my situation:

I moved to a block of strata controlled apartments a few weeks ago as a tenant (not an owner). There are 3 car park areas on the premises – 1 either side of the building are for residences and the middle parking area is for vistors – although none of the areas are signed. 

I initially got a letter on my car (parked in a resident parking area) as no-one notified the strata committee of the new numberplate as being a resident. After that was cleared up, a couple of weeks later the owner of the apartment received another letter saying that my car had been in the resident parking area “for the past 10 days and appears to have only moved briefly twice in that period”. the letter then goes on to explain that in their opinion the vehicle is not being used on an acceptable basis as the car park isn’t to be used as a semi permanent storage space. 

all the committee members signed the letter.

To me this seems a little psychotic to raise an issue about a car only being used a couple times a week – but hey i’m new to strata controlled apartment blocks.

So i guess my question if the above happens to be a legit complaint, is what’s defined a semi permanent storage? I drive the car 1-2 times a week, sometimes more. Should there be appropriate signs pointing out a time limit on the car parks if there is an issue of long term vehicles? This entire dispute is in the resident parking area not the vistor parking..

thanks
