My heart tells me it is probably a lost cause if you've got a borer there but you'd probably have to identify exactly which elm and which pest you have. Photographs are a real big help if you don't know.

I'm not sure what "golden elm" means in Australia -- is it even an Ulmus? Could you also send the Latin name along with the photo?

I don't have a photo, but the latin name is Ulmus Glabra Lutescens.
I can't identify the pest. The tree secretes a frothy,crumbly substance which my nursery man says, is its way of trying to protect itself. We are still in the middle of a drought, one of the worst on record,and last summer was also the hottest, on record, for January. This stress and lack of moisture for the tree, makes it an easy target for beetles and or borers, many elms and natives in the town have died. Old timers tell you the only way is to push a piece of wire up the holes and spear whatever is attacking the tree, I haven't got the time or patience. I was hoping someone from another country might have a tip,mainly a poision for pests.

The old wire trick doesn't work. When you see the opening made by the borer it's because he/she already tunneled to the surface and escaped.

Check with your agricultural authorities or other Australian gardeners to see what's legal and available there. Here in the US we might consider a systemic insecticide like Merit, applied as a soil drench, if the pest is a beetle-type borer. But the first task is to take a sample to an entomologist and determne what it is you're fighting, and thus what season you might apply a topical treatment to halt further infestation. Know thine enemy.
