We bought some wood chips a couple of weeks ago and they were very helpful. They have competitive prices and you can borrow their trailers for free.

Approximate cost: $40 for 1/2 sqm

I have found both of there garden and building supplies to be excellent. We have purchased everything from red gum chips to sleepers and compost. They have been extremely helpful and reliable. They deliver for a fee or you can hire there trailers for free and do it yourself.
