Hi @curo123,
Thank you for asking if your tree has crown gall, from what I can tell, it doesn't look like this is the case but let me tag in our garden legends @Noelle, @Adam_W, and @mich1972 to see what they think it could be. Do you know what type of tree it is? That might also help identify what could be going on.

Hi again @curo123
Crown gall affects the "crown" of the trunk where it attaches to the root system.
This is definitely not crown gall. In fact, if the tree is a lillypilly as the leaves might appear to be, the appearance of the rough bark is quite normal and not really anything to be concerned about.
Hi @Noelle,
I think the tree is a glory bush. I hope it’s not too sick.
Hi @curo123,
Could you please show us the leaves of this tree so we can assist in identifying it for you? Tibouchina are typically shrubs or small trees. The trunk looks fairly substantial and more so a medium to large tree. Are you sure it's a glory bush? If we can positively identify the plant, we'll have much better luck at providing an accurate response to your question.

Thanks Mitchell. I hope you can help. The tree looks unwell.
To confirm, @curo123, are these Tibouchina leaves you've just posted from the large tree trunk you posted earlier? Tibouchina typically has very smooth trunks, which makes me think these leaves and trunk don't go together. Is it not a smaller shrub growing next to the larger tree? Regardless, the Tibouchina leaves look quite healthy. Is it just the rough bark that makes you think it looks unwell?

Hello Mitchell,
It’s all connected. The trunk doesn’t look well.
In that case, let me mention @Noelle and @AdamW to see if they have some thoughts. There does appear to be some borer damage or a decay issue going on within the bark layer. What's the drainage like in that area? Tibouchina are quite susceptible to root rot from poor drainage and excessive moisture.
Mitchell
Yes, I agree, the leaf does not look like a tibouchina or glory bush. It looks much more like a lillypilly leaf but I too would like to see a close-up of a couple of leaves to be more certain. The bark does not look like a disease - it just looks a little gnarled as some trees do. There does not appear to be any rot.
