I have a prolific growth of a woody vine outcompeting the established native trees(Eucalypt, Baksia, Angophora, and understory plants) on the north facing sandy section of my land. My locatiion is just north of Sydney, NSW.vI cannot identify the vines but they are not listed as introduced weed species and are woody stemmed, the leaves are sturdy, not really a thick cuticle with sturdy stems. Any suggestions to source information or identify the vines. cheers
