You need to suggest something or the weeds people won't be alerted. I can't see details of the bracts but if there are 19-21 bracts and 13-15 petals and you suggest Madagascan fireweed someone will take a look and remove it.

it doesn't look quite the same as the unidentified yellow daisy Unidentified Daisy (TBC) - the leaves are different.

I agree Mike, they are different.
After more internet research I'm now pretty sure it is Senecio madagascariensis.
I searched the area but couldn't find more (flowering) specimen.

Species id confirmed by Mulvaney and Taylor. I removed & disposed of the specimen and checked immediate surrounds for more - I could not find more however non-flowering seedlings might be present.

Thanks Waltraud - there seems to be plants appearing in north Canberra. I wonder what the source is?

no idea Michael also I.m not sure how far the seeds blow...

I thought it came from landscaping in Crace and despite major efforts to control it the plants have travelled along the tramline. It would easily blow over from Nortbourne Avenue.

Couple of CNM records of the species for Mul flat but not Gungahlin subs.

Major infestation occurred before CNM.
