I just clicked on your link [5 hours after your post] and the panel on the left shows 18 warnings of active bushfires or smoke over roads etc, 25 incidents of house fires, car accidents and similar, and at the very bottom of the list it states there are no prescribed burns listed by the W.A. Department of Parks & Wildfires.

Nearest thing to a prescribed burn that I can think of, would be back burning in an effort to contain an active bushfire.
Prescribed burns are usually planned well in advance - but if the weather conditions are wrong, or there are insufficient firies available [volunteers and fulltimers] the planned prescribed burn would / should be cancelled or postponed.

Yes checked this morning and they have all been removed. Doesn't look so busy now.

Next 2 days look ok for a burn down that way. Light winds and low temps.

^^^Could it not be that they are allowing the change in the wind work for them and burning back to create a firebreak?

They did say when the wind was light they managed some back burns, to help contain the fire.

And again today,.. massive effort to control an massive out of control fire and yet they have crews doing a prescribed burn.

The info on the map says " No planned ignition today".
The black symbol on the map indicates a planned prescribed burn. That doesn't mean it is alight, but I presume "Active" means that it could be under the right conditions. Presumably the proposed burn has met planning criteria and has been approved to proceed under appropriate weather conditions. I doubt that would be while a major bushfire is occurring and requiring massive resources.
