This plant which is now a very fast growing tree is spreading seedlings everywhere, see photos.
Can anyone advise what it is and what should I do?
Looks to me to be a feral pittosporum, best plucked as soon as spotted or cut close to ground level and the stump treated with roundup or similar. I believe that Don Bourke referred to them as bird poo plants, birds eat the fruit and deposit the seeds far and wide.
Queensland box ?
I've had two of these scrubs at my old place. Very hard to grow here in Adelaide. but once you get them going, they are happy. They don't like hot weather (particularly the box tree). I would love to have them at my new place, but nurserys don't stock them.
Best of luck getting rid of it. No tips from me other than Zero poison.
Yes pittosporum undulata. Not technically a weed on the east coast but grows well and some bush regenerators advocate a bit of thinning to allow other less tough natives room. It's definitely considered a weed on Lord Howe Island.
But jump on the ground asparagus, you've got a lot of that I can see. It overtakes beachside vegetation, a weed of national significance. Dig them up, hang them out to dry. They are so tough. They came via caravan parks, as tough ornamentals to put in hanging baskets and still be alive when you came back to your onsite van once a year. Birds spread the red berries.

Yep bird dropped at our place, got it in one of our garden beds going crazy, my beloved looked it up, found out what it was and put the exterminate note on it.
Gave it regular sprays of glyphosate at first including some special batches as it just shrugged off the normal batch.
The root mass was mental, bit like a tumor you've got to dig well around it as if you leave a bit there it'll come back.
Still finding stray shoots after 4 years but that's annoying but controllable.
What it is and what ever you do with just eithet blame climate change or say it's gods will.
Easier than trying to understand nature and both similarly useless answers that will be defended by religious nut jobs.
