"Trees in Newcastle is a local native plant nursery, volunteer & education centre and provider of bush regeneration services" (off website) I received a quote for planting of plants, mulching etc for my company however my experience with them was not pleasant. I think what they do is great but was put off by the lack or organisation when tryiing to contact them, getting somone out for a quote and then finding the representative to be quite rude. We didn't go ahead with them.
