Many thanks everyone. I hope we win.
Here is a spiel on the wasp.

Here is an article about the wasp being introduced in the south. Our local council, Redland City Council, has not.

This morning I spent several hours mulching the leaves I removed, which I will compost. This is one recommendation. The fungus infection is much enabled by the leafhoppers sugary secretions.

In the high winds last night, no new branches fell off the palm.
Elaine, the leaves fit so tightly with each other in a screw and I wouldn't be able to get the soapy water between them. As well, it is 10-14 feet high and I am very unsteady on a ladder in my older age. (But I would try it if I could. I will have to think of something because the systemic doesn't last).
This also means I cannot get up high enough to get off all the diseased leaves which is much recommended. So I will have to pray here a bit despite all my good intentions.
The rot really does smell.
