Wouldn't that be a decision best left to pilots who are on-the-spot, once
the task had been cancelled?

According to the local rules, input was allowed from various sources and they apparently pointed towards cancellation.
Sylvia and Kathy, due to their early start, got away from the worst visibility earlier and without that mess (especially in reduced visibility) called a gaggle. Where they were as the task was cancelled was not bad, and there were just the two of them.
Oh, well...

Visibility today is better.
They're all on course.

Something to give you an idea of the visibility is look at the Keepit webcam in the morning AEST.

Before we left for Australia, the tree line wasn't always visible.
