It is most likely that flushing of Outboards will not be permitted when we go to level 5. Not allowed in NSW or Victoria even at Level 4.
This will put the argument to rest about whether flushing is even needed if the motor is used regularly. Built up salt should dissovle in water during each use.
Suppose all those panic merchants can flood up to Caloundra and use up the abundance of Baroon water... Might teach the Water Wallies up there a thing or two about the value of water when it runs out.
