your question is a bit vague, so I'll assume you are referring to a primary vote.

the answer to that question is a 'no'.

however, some of us know that it is a bit more complicated than that.

Mandatory preferential voting makes it impossible for me to put the incumbent Daniel, the Liberal Wilson, Labor and Greens ALL last at the same time. I have to nominate them ALL in some order. Only the LAST candidate will be denied my vote.
