No. A vote for a Community Independent is an extremely effective way to show the major parties you're unhappy with their leadership. If you want to vote independent or for a minor party, but also want to ensure a major party is kept out of government, you can put that party last on your ballot paper. This ensures that your vote will not flow to them, no matter what. This is the beauty of our preferential voting system.
The more independent voices we have in parliament, the better they will be able to hold the major parties to account.
