It's called Springbank Island, Kasko!
Ok this is not very exciting, but if you love your doggy it's a nice spot. We had an SAU Xmas BBQ down here one time.
Name: Lazeh River Day
Location: Uriarra East Reserve, drive down the Cotter Road, turn at Uriarra Road, keep driving until you get to it
Activity: Only about 20mins from Weston. Laze around in the river in the sun, free from the dog nazis Lots of other friendly people who love their pupsters too. There's a "beach" and plenty of separate little spots if you want to get away from everyone else. Enormous grassy area to have a picnic or BBQ.
Items needed: Swimmers, sunscreen, beers, stubby holders, food (optional ) and dog!
Extras: Check if there's a fire ban before planning a BBQ as they are wood. On that note you may need to bring some firewood too.
