You have spotted him (or her) of course. I was also at work, of course, but was rebuked by two yellow-waistcoated municipal employees for being too close to the water’s edge. I just restrained myself from giving them the finger. There was a knee-high fence and a sign which said “Restricted Area. No Fishing. No Swimming”. I took this to mean entry was allowed, as this is Canberra where, if they want to forbid something (and they often do), they leave no room for confusion about their meaning.
