On Lake Macquarie, yes, the yachties were 'dragging the chain'.  Sunday was breeze less and cloudless.

Winter approaches and the sun's rays get lower and lower on the horizon at Croudace Bay and all over.
House design is best that makes good use of where the sun reaches over the seasons so as to save energy and decrease the carbon footprint and save money over heating and cooling.  Insulation and water tank requirements are in place. Maybe more is leglislated. But that's just the start.
For instance, in this climate, it is madness to build a home with next to no eves to provide shade while designs that use passive solar heating and passive cooling and lessen dependence on air-con are quite possible and responsible as earthlings if we could break away from suburban conformity.
