So does the QLD legislation list the things that are OK or does it just give some examples? I would have thought a very good case could be made that a clothes line is sustainability equipment. IE it is a solar powered clothes dryer that is more sustainable than an electric dryer, just like a solar water heater is more sustainable than a straight electric water heater. In the ACT a clothes line is given as an explicit example.
I would have thought that the OC might only be able to ban the use of a solar clothes dryer on a balcony if it provided a practical alternative place to put one.
The ACT (following my suggestion in a submission to the Unit Titles Act review) has the following (slightly condensed quote):
S.108 (3)d. An amendment to the Rules has no effect to the extent that it results in the rules … prohibiting or restricting the installation, operation or maintenance of sustainability or utility infrastructure.
…
(a) means infrastructure and equipment that—
(i) improves the environmental sustainability of the units; or
(ii) reduces the environmental impact of the owners corporation and the unit owners; and
(b) includes related utility service connections and equipment.
Examples—solar panels, clothes lines, rainwater tanks.
