When and how do PD politicians vote with the people?

A:

PD politicians vote with the majority votes from voters in their electorate. If only one person votes they will vote with them so if you wish to support or block a bill your vote is important. If no one votes and they don’t feel they have the experience to vote on the bill they vote with the majority of votes in their state or Australia.

PD politicians vote with the people on the 3rd reading of bills in parliaments.
