Actually, this isn't Jubilee Creek picnic site at all.  Jubilee Creek is correctly tagged in a slightly different location: https://www.openstreetmap.org/node/817695840 (source: I was there on January 9th).

Not sure if one of the group I was with kept the map of the area we were given at the entrance gate, but if we still have it, I may be able to figure out the correct name.
