Most lakes, like most land, is privately owned here, so water sports, fishing and such typically doesn't occur. Lake George, the largest freshwater lake in Australia when it's actually got water in it that is, is no exception. There's no fishing, no boats, not yatchs and so on. The only exception is for people who own land at the lake shore (and the paragliding club).
We've seen 2 wind surfers in the 7 years we've been here. That's a hazardous sport when under the water's surface are kilometres and kilometres of barbed wire fencing! The lake has been divided into fields for sheep grazing and cattle, both of which currently are elsewhere and the cattle at least explain the 2 beef cows I've seen hit on the highway. First one was by a lorry who just didn't seem to comprehend what was standing in the carriageway in front of him, despite my hazard lights and very rapid lane change. The second was hit by a car. The 2 occupants were air lifted to hospital in a bad state.
What you see more often are paragliders by they either have to be very careful now or use the alternative jumping off point. They used to land on the ground well into the lake area and someone would drive out to pick them up. Not so practical currently! Lol.
But it is great watching them soaring and spiralling on the thermals. Just wheeling around having fun. Watching us from the car as you drive along the highway or from one of the rest spots along the lake shore (no less than 5.) To be honest, everyone here is happy to see them back because it means the lake is recovering from when it dried out completely for several years before and during the black summer fires.
