An enclosed kids playground has several triangular shaped knitted shade cloth panels erected to provide sun shade. The site is in Maroubra NSW located quite close to the ocean. A series of still images was taken when there was a "moderate" sea breeze blowing. It is unlikely that the kids and supervising parents would be still using the playground in a gale.
It is clear that the vertical movements and clearances to fixed objects such as towers, "forts" needs to be adequate. Here the movement might be plus or minus 800mm.
