I think there has been quite detailed discussion re privacy before, but just to clarify in relation to what Jimmy said here:
The Privacy act alluded to basically only applies to government handling of your information plus organisations that have agreed to a set of privacy protocols.
The Privacy Act applies to private sector organisations/businesses with a turnover of $3million or more, it is not limited to Government agencies. It may also apply to an operation with a turnover of less than $3million in specific circumstances.

In many cases strata managers are bound by the Privacy Act and must comply with its requirements.
Your name is not personal information of itself. Refer here:
