I thought exactly the same thing!

For those unaware, Queensland (population 5.185 million) _still_ has yet to have a large scale outbreak since March 2020.

It's common to have windows permanently open with fly screens here. And houses in the typical Queenslander architectural style[0] are up on stilts and deliberately laid out to encourage a breeze pulling air from front to back. Rooms are often not sealed, with fanlights above door-frames allowing in airflow. This design philosophy extends to commercial buildings as well.
