Maintenance of parking spaces

I’m in a 38-unit scheme on the central coast. Until recently, our gardener would regularly leaf-blow the leaves, dirt, and debris that would accumulate in our allocated parking spaces.

We have all just received notice from the executive committee that it is NOT the gardener’s responsibility to undertake this work, and residents must sweep the leaves out of our own parking spaces.

Our scheme does NOT have a by-law / special resolution that makes each owner responsible for the sweeping of their parking space, therefore I believe this latest assertion by our committee is in contravention of section 62 of the act. Comments?
