Victoria doesn't need immigration if the consequent population growth necessitates the theft of water from the Goulburn Valley (see http://www.plugthepipe.com) or the destruction of Port Phillip Bay to accommodate the larger ships claimed to be needed (see http://www.bluewedges.org). I commend the articles:

"Melbourne 2008: Life in a destruction zone" at http://candobetter.org/node/628 and

"Melbourne protests mass population growth and its profiteers" at http://candobetter.org/node/637
