We will explore the Murrumbidgee corridor at Tharwa Sandwash, which is accessed just south of Tharwa from Smiths Rd.    Meet for carpooling in Lanyon Marketplace carpark at 9am, the section on the right as you turn in on Balcombe St.  Please come prepared for all weathers and wear sturdy footwear.  A couple of hours should be enough and we may visit Namadgi Visitors Centre afterwards if time allows.  Booking is essential.  Contact Lia Battisson at liabattisson@grapevine.com.au before 1 July; please provide your name and mobile number, and the name and number of an emergency contact.
