There is a native grape which has no grapes, called Cissus Antarctica , which is good for shade on wires and trellis and lets the sun in in winter being decidous. Twining plants are good but those that bind on will ruin paint and brick, as they did my old brick office.
Dwarf Lilly Pilly are a low fire risk species which will hedge up to 3-4m and shade the wall while staying 1 m away and not risking termite ladders. Avoid any conifers or light weight exotic species which are like Roman candles.
