I don’t think you can charge people money to use property they already own! On the other hand you can create by-laws to govern reasonable shared use.
The exception would be where an owner is granted a ‘special privilege’ (is this the same in NSW jargon?) for exclusive use of an area of common property. In that case all sorts of conditions can be included. In our case, many owners have been granted special privileges for exclusive use of particular parking spaces on common property. We have ensured that these are equitably distributed among owners because of the fundamental principle that all owners should have the opportunity for equitable use and enjoyment of the common property. Had it not been equitable the resolution would not have passed (unopposed is required in the ACT, special resolution in NSW). The special privilege allows the storing vehicles with limitations on the storage of anything else that might be a hazard or eyesore. In exchange for the special privilege, the benefitting unit owner is obliged to meet the owners corporation’s costs for the construction of a carport roof over the area and subsequent maintenance costs.
As for bins, a common by-law would be one that specifies where bins may be stored on common property (say, purpose built bin enclosures). It is then a breach of the by-laws to leave bins anywhere else.
