Do I have a sick Gumtree?

[u/Mountain_Text_3172]

The tree is shedding lots of very thick bark and plenty of dead small branches are falling.

I've included a pic of some of the recent bark it has shed, which is thicker than my thumb.

There are also deep cracks up the trunk from almost ground level and then the lowest limb has some kind of deep rot with fungus in it.

I'm unsure what type of gum it is, but it's not a smooth bark variant I'm pretty sure. Keen for some opinions 🙏🏼

I’m not an arborist but those cracks look huge. I’d be worried about borers getting into it or water rotting it.
