Paddle everywhere!
Port Authority will come check you out if near port but all cool paddling all the river
worst is all the toff rowers (put in nicest way possible) around swanston st bridge who think they own the water, love yelling at you and thinking they have more rights to the water than anyone else. Sadly they give any good rowers a bad name.
Lol, my now step daughter is one of those rowers and that is exactly their attitude to Sup on the Yarra. I suggested doing it once and was told I would be an inconvenience to rowers and should not do it because it puts them off!
The Banks rowers should be ok they are the Drinking Beer club and seem a bit chilled but when the girls schools get in they are less aware of the world as we know it,lol.
if the boats are heading your way just keep to the banks a bit more or carry a megaphone to warn them off.
