I have a large black wood that has been dripping water from its leaves consently for about a week and development foam in blobs on the ground and the leaves. I have seen trees produce a foam usually after rain on the trunks After hot period but it has not been extremely hot nor has it rain a lot.
This is in Tasmania
Can anyone give me a clue what is going on

Saponins in the leaves as well as bark will cause this but usually after rain. See this thread https://bushwalk.com/forum/viewtopic.php?t=24730

Several of my grevilleas, blackwoods and wattles produce foam globs where the leaves (or phylloclades) join the stem, or where a cluster of them join the stem.

This is after no rain for a long time, and not from the trunk. They are doing it a lot right now.

It's weird.

Pretty sure there is an insect that produces bubbles as its protection.
Spotted some on a stem of a dwarf golden penda a couple of weeks ago. Not dripping, just along a twig junction.
