She is one of 12 Tasmanian senators. I'm not sure about other states but generally there is a strong point of difference between state based politics and those representing the state federally.
Yes you are correct with the 12 senators.....I was thinking of six who are elected in the half senate elections.
But they represent their appropriate states and should listen to the state governments and the people of that state as to what they consider is desirable and advantageous to their state irrespective of their own personal beliefs.
