It would be really helpful if you could tell us where in the world the plant is growing.

Hi, it is growing in Sydney Australia, in my backyard, thanks very much, Van

If this is a plant you do not want growing where you do not want it growing it is a
"weed".

Perhaps your University of South Wales has an Ag School that could help identify what you have.

It looks like a papaya seedling.

Hi, thanks very much for the advice. I remember I put the papaya peeling and seeds I the vegi psych few months ago, maybe a lot of them germinated, -:)
