I understand that this topic does arouse passions! I think the trend is to tolerance and even encouragement of open air drying on environmental grounds. Reducing the use of electric clothes dryers is very low hanging fruit among the range of measures one can take to reduce greenhouse gas emissions or reduce your electricity bill. In the ACT a Rule (Bylaw) is now invalid if it prevents a sustainability measure. I think balcony drying could only be banned by an ACT OC’s Rules if the OC provided a good alternative such as roof-top drying or some other location that was sufficiently practical for residents, at least that is my interpretation. I think QLD has something similar.
