What area of QLD are we referring to?
Many city councils offer a number of local indigenous plants for free
several times a year, and also state they can offer advice for suitability.

hi all
anyone have any reccomendations for trees or shrubs in QLD, i am on tank
water so they MUST be very drought resistant, prefer something that might
block some of the dust from the gravel road i have at my place, anything
that may add colour to a bushland setting.
thanks
Paul
