"Turbina corymbosa (Convolvulaceae) and yes it is a weed.
Recently photographed it again near the Curtain Fig in full bloom, and its also on the banks of the Barron at Kamerunga.
Quite spectacular in flower and as a mature liane it also develops incredibly ropy contorted stems, would be worth growing somewhere with zero potential for it to naturalize, eg middle of Saudi desert, a glasshouse in the Yukon, in the middle of a concrete
jungle with stormwater draining directly to the sea etc.
I also recently photographed at Nong Nooch BG another sp in the genus from New Caledonia with brilliant crimson flowers which seems to be a much tamer Turbina."
