First of all, KiwiPaul was quoting by-laws which may not be the by-laws you have for your scheme and aren’t the current model by-laws for NSW.
The model by-laws that I pulled of the web this morning are slightly different (see below) but that is hardly the point. It’s the by-laws that are in place in your strata scheme that matter. Model by-laws may have changed since yours were adopted, but your scheme’s by-laws will only change if you and your neighbours change them.
So look at your own by-laws and what they say. If they say no one can park on common property ever, that that is the prevailing rule for your scheme. But FYI, here are the current model by-laws that will be adopted by most new strata schemes. Again, yours may be different and you will have to read them to discover how.
2 Vehicles
An owner or occupier of a lot must not park or stand any motor or other
vehicle on common property except with the prior written approval of
the owners corporation.
3 Obstruction of common property
An owner or occupier of a lot must not obstruct lawful use of common
property by any person except on a temporary and non-recurring basis.
