Plant Identification Help

Melbourne, Australia

Hi all,
Found this plant self sown in my yard (Melbourne). Images attached.
It has hairy leaves with pailer undersides. The larger leaves are lance shaped, there are also smaller round stipule leaves growing directly out of the plants stem. Google searches aren't coming up with anything so was hoping someone could help.
Thank you!
Edit- Probably should have put this in the Plant Identification Forum now that I think about it whoops

I had no idea but I figured a seedling so robust must be a weed so I googled weeds of Melbourne and went down the list.
https://weedsofmelbourne.org/classification/solanaceae

On each I googled first their stem and if looked possible, googled its seedling form photos. At Solanum mauritianum, I thought it might be a real possible winner or a relative.

It sure looked like the stem with those unusual stipules.

And its seedling form
I read a general description of http://publish.plantnet-project.org/project/plantinvasivekruger/collection/collection/synthese/details/SOLMR
and

If it is a Solanum mauritianum, you should destroy it.

I was closing my research windows and see I forgot to post thIs article on Solanum mauritianum in the Brisbane newspaper.

CAUTION
"Be aware that some people react to the fine hairs that become airborne when working with this weed. Cover your arms and mouth.

The whole plant is covered by fine hairs which are easy to dislodge and can cause respiratory symptoms to humans and animals.

All parts of the Solanum mauritianum plant are poisonous to humans, especially the berries and handling the plants can cause skin irritation and nausea.

The dust from the plant can cause respiratory problems if exposure is prolonged."
