Thanks turtle
It seems rain needs some sort of nucleus to form around, ice, dust ?, or 'something' exhuded from plants or trees(?)
Most of Oz (75%?) would be fairly tropical so I doubt if there would be ice clouds in those areas.
The CSIRO did (historically) a lot of work on cloud seeding
But it seems to have been discarded as dead end science these days

It seems my dandruff may be making a contribution however!
Airborne dandruff can turn on rain

The researchers turned up a collection of human and animal skin particles, fur, fragments of plants, pollen, spores, bacteria, algae, fungi and viruses.
The particles ranged in size from tens of nanometres to several millimetres, and varied depending on the time of year. For instance, pollen was more common in spring, and in winter there was more decaying cellular matter.
As much as 80% of the particulate matter collected was biological in origin, ranging from 15% over the Swiss Alps to 80% from the Amazon and Lake Baikal in the autumn.
On average, 20 to 25% of the aerosol material they collected was biological.

I still suspect that plants may be
deliberately producing rain.
If they can talk to other plants with chemical messages-why not?

Essential Oils are very volatile and are usually found in Mediterranean or hotter climates.
Are they a part of the story? aromatic molecules would be nano sized.
There is frequently a symbiotic relationship between plants and soil 'wee beasties'
