AusBonsai

So driving home i noticed the apprentice finishing off the tail end of maybe 1000 plantings along a recently renovated road, i spied a big pile of seedling/tube stock trays so i quickly (and safely) stopped and asked if i could grab a few...a boot load later i also noticed the few plants he still had with him, he mustve noticed me looking and said i could take a few-into the car they went. Question is...what are they and are they any good for Bonsai...
other Identifying features - no smell, pines not "soft"
Hope to hear from those whose knowledge base exceeds mine.

Cheers in advance

They look Callistemon to me, maybe C. "Injune" cultivar. with pinkish flowers.

I would say its Grevillea 'Canberra Gem'... hard to be sure without flowers...
