I have stayed at Boomerang Beach about 20 mins south of Foster on 2 occassions to kite,
Many times surfing
first time did not kite as there was no wind


and the second time kited Elizabeth Beach and Boomerang Beach


There are heaps of great stops there


long sandy beach from Bullpaddocks heading north towards Foster ,be great for a downwinder,think there might be a bus runs along the coast road there too,kite up or down and jump on the bus back

Good flat spot in Myall lake in a SW or Southernly,kite from the Sailing Club about 3 km north of the Rec club at Boomerang,not far from Bullpaddocks camping area
Smith Lake have great flatwater spots in SE or E winds
Around Foster /Tuncurry kite just north of the lake entrance in a NE or a bit futher north in a SE
And there is Old Bar further north of Foster,flatwater spot and open surf spot,Very good spot
Did not see any other kiters while I was there at Boomerang
And my mate who lives at Boomarang has never see anyone kite around the local beaches near his place
But Im sure there have been plenty of kiters passing though that have kited there form time to time
Great part of Oz,crystal clear water
