Jezza's on a good thing there.
Being both a model and a bamboo nut using the real stuff is the way to go.
Find a large, mature bamboo and use the top of any bough that looks thick enough. Certain types of bamboo are better for this than others. You don't say where in Nsw you are - but if in Sydney in the Royal botanical gardens near the stairs of lady McQuarie chair is a large, mature clump of a lakso bamboo.
The foliage is superb - base coat, detail nodal growth areas, drybrush then spray with white glue/ water mix (60 /40 mix ratio)
Then sprinkle on long sinewy bits of foam growth (woodland scenics etc) , quick spray of dullcote and it looks great.
PM if you would like some posted - Cheers,
Andy.
