Any other recommendations for screening plants and climbers will be much
appreciated.

Native trees I like are casuarina, hakea, callistomen and melalucas
(sp?).

I recently made some bean and climbing plant trelliss from 3 m lengths
of pipe (700mm in soil + 1 bag of concrete) and half a piece of slab
mesh (slab re-inforcment mesh 6"x6" size). I actually had 2.5 full
lengths offered to me.

Onto this you can place boganvillas (various reds & oragnses +),
Pandorea Pandorama - white(common name?).
