Its not a scientific poll so cannot be taken as an indicator of the actual position.
These online polls that anyone can vote in can be hijacked and the position distorted.
I posted a similar poll earlier today on the same topic and it reflected a reversed position with a majority against a ban. It was a much larger poll but still cant be taken as accurate for the reasons cited above. A scientific poll on the issue by Essential or Newspoll, or Ipsos or Reachtel would provide a more accurate indicator.
