On the second point, my submission to the current review of NSW Strata legislation (copied to my State MP) included the following:

Recommendation: a model by-law should be drafted to allow schemes to stipulate that designated parking spaces are to be used only for the parking of vehicles, and that storage of goods must be only incidental and not such as will significantly encroach on the space and prevent parking of the owner’s vehicle within the space. This should be linked with a strengthening of by-laws relating to parking in designated visitor areas and directions to the CTTT that the preservation of visitor areas for their intended purpose should assume priority in the adjudication of disputes. Any such by-law should explicitly prohibit the storage of fuel, chemicals or other hazardous objects or materials (e g storage batteries containing lead or other toxic metals).
