Preference votes in Council elections

I am concerned about the distribution of preference votes should my elected representitives fail to gather enough votes in the upcoming local elections.

Being aware of the fiasco that took place at the last Launceston council elections (re: preference votes), I would like to know how I should vote in the forthcoming West Tamar Council election, to ensure that the anti-pulp mill candidates get elected.

Is there a preferred strategy or numbering system?

I know who to put last :-)
