MattB I accept I was party wrong but here is the default bylaw for NSW
2. Vehicles
An owner or occupier must not park or stand a vehicle on common property without the written permission of the owners corporation. That permission can be cancelled. Permission does not give an owner or occupier a permanent right over that part of common property.
So the OC (in QLD the EC can grant this permission also) can grant permission for residents to use the common property without the requirement of a SR or a bylaw.
I would suggest the resident who wants to take advantage of this is charged a comercial fee to prevent others doing the same thing. Granting permission to park without a good reason or a fee would enable all residents to park outside on the common areas otherwise they could claim discrimination if only certain resident were given this permission for free (owner occupiers being given permission but tennants denied).
In fact reading the standard bylaws most refer to without the written permission of the owners corporation and as the EC is the representive of the OC I feel they might have the authority to grant this permission anyway.
