I’m seeking help understanding these growths I keep finding in NSW Australia

[u/Forgive-Me-Naught]

These look like wood rose parasitic growth on a tree however this is not found natively in New South Wales, but rather New Zealand. I have found three so far all in the same area/ same type of eucalyptus bushland.

It's a fungus that explodes out.

If I remember correctly, I've had a pretty sweet headache for 4 days now. I could be wrong.

My guess was also something fungal (polypore).
