The Scientific Expedition Group run two surveys at Minnawarra each year, Autumn and Spring, and usually timed to co-incide with the first few days of the school holidays. This would be an excellent opportunity to take the children, your nieces/nephews, or grandies!
The survey is conducted on Springmount Rd at Hindmarsh Tiers, near Myponga, about 1 hour south of Adelaide.
