Can anyone tell me why my corky bark elm is yellow on the leaves. I live in Queensland Australia. Its autumn/fall here our temps are still high 20s to low 30s degrees C. Am i over watering or under watering. I have noticed ants in the soil may be a nest
Looks too wet. We’ve had a nice wet winter and my cork oak started looking like this on consecutive rainy days.

It is early fall so you might also be starting to see some fall color as the daylight length decreases.

Looks pretty normal to me. The pattern of yellowing leaves seems to be the oldest growth still on the tree. Its normal for it to yellow and drop eventually.
