Used to be known as Senecio mikanoides, but is now called Delairea oderata, German Ivy.

Yes, it looks like Cape ivy (Delairea odorata) http://www.esc.nsw.gov.au/living-in/about/our-natural-environment/introduced-plants-and-animals/weeds/weed-profiles/cape-ivy-delairea-odorata,-formerly-senecio-mikanioides

Thank you both,appreciate it.

Common or English ivy (Hedera helix) and Irish ivy (H. hibernica) - the common, weedy "English" ivy of my area - flower also. It's just that these plants have a creeping, vegetative life stage followed eventually by a shrubby, flowering and fruiting mature condition. So you won't be seeing carpets of ivy in flower unless the shrubby growth has started to develop in the same plantings or colonies as well.
