A letter sent to residents from the MP (October 2009) says that residents without Internet access can request a paper voting sheet. However, that information is not on the web site (some residents may have Internet access, but not want to use it to vote).
Also it is not clear why criteria different to state elections have been used for selecting voters. The "register to vote" instructions state that the voter must "... live within the boundaries of the Balmain electorate ...". As a result some citizens who are eligible to vote in state elections in Balmain may have been disenfranchised in this referendum.
In addition the referendum details are on a commercially registered web site ("verityfirth.com.au" registered to "ServEssence Pty. Ltd."). Given that NSW has a history of corrupt practices involving the administration of funds at the local level, it would be prudent for this process to be conducted by the NSW or Australian Electoral Commission and all details to be on a ".gov.au" web site.
