First Chemtrail I’ve seen over Australia in a long long time

Contrail.

The sky is obviously saturated and cold. Add more moisture and OF COURSE it will leave a cloud.

I saw it too. I have a pic too. I woke up to it

add more moisture by spraying chemicals???

There is no such thing as chemtrails. That is exhaust from jet engines.

contrails disappear within minutes chemtrails are visible
for hours

they only spray them in winter for some reason!!!!!!

No, by producing water vapor through hydrocarbon combustion.

It's complicated. YOU aren't expected to understand the science.

Please continue to believe you are being sprayed like a bug. I'm glad you believe that.

...says all morons.

If the air is saturated with respect to ice, and never gets above a certain temperature, and there is no wind, HOW does the trail "disappear"?

(this should be good!)

Chemtards...the dumbest people on the planet

Everything you said is wrong. The air is billowing around constantly. Churning and mixing. Caused by (just like "climate change") the sun. In addition to having had an airplane fly through it at 500mph.
Your debunking skills need more work.

have a look at the weather to keep people indoors just before each major lockdown lately and u will have your answer
