A Hypericum I would say. Can't tell you which one without some idea of habit and size. Candidates might be H calycinum or H patulum. It might also be a seedling from a hybrid like 'Hidcote' in which case it may not have a name.

floraluk- 'Flowers may have a scent or not. Leaves may have a scent or not. Flowers and leaves on the same plant do not necessarily smell alike.' So, I guess I can conclude it is not the Cherry Laurel because the leaves should have a scent regardless of whether it flowers?

Beware! Jatropha is a large genus (nearly 200 species).....All of which are poisonous to some degree-several are deadly! There is one Jatropha commonly grown here in Florida that attains small tree proportions that for some reason many people think is a Pistachio tree (?). Nope; and eating enough of the "nuts" may kill you....not even in the same plant family as the real Pistachio. breaking g., where do you live in Northern Queensland?

I would venture to say you have a cruenta hybrid. Probally 'Pink Champagne' widely grown plant in the industry. Pups will be greener until they have a full root system and actively growing. Plant looks better in a lot of sun. The hard leaves will tolerate the sun. I grown mine in sun from 8am till about 1pm.
