Not Canberra Gem because the leaves are not needle like enough, but may be a cultivar or hybrid of Grevillea juniperina which is one of the parent species of the Canberra Gem hybrid
Mike there are so many different Grevilleas behind the houses on Farrer Ridge this one is right next to a fence with another variation beside it. They hybridize so easily I wouldn't think G. juniperina would be found on Farrer Ridge.
