@MichaelMulvaney, I found these plants around a year ago and it must have slipped my mind to tell you. I just happened to pass by them on an evening walk, and made a "rediscovery", is there anything that can/should be done?
Just back from Kangaroo Island, where i spent 30 hours digging out bridal creeper bulbs on my sons property will call in on householders and see if they are happy for me to try and remove plants
