I am trying to rent a place in Sydney, Australia. I believe this question remains valid regardless where you live.
When renting a place, a real estate agent is permitted by law to ask for as much personal information as they want, such as your passport, your Medicare number, your Centrelink customer reference number (social security identifier), your driver licence, your birth certificate, your employment history, your rental history, your education, etc.
They are also permitted by law to disclose personal information to residential tenancy database operators for screening purposes, such as National Tenancy Database (owned by Equifax which infamously leaked personal information of 145M Americans to China in 2017) or Trading Reference Australia (investigated by the Office of the Australian Information Commissioner in 2020 for potential data breach).
As a privacy-aware individual, this really worries me. I don't want my personal information ends up in the hand of information brokers (legal information thieves in my own opinions), such as Acxiom, or even worse, in the hand of identity fraudsters. With this amount of personal information, it's more than enough to impersonate or blackmail me.
While in theory, personal information cannot be collected unless it is "reasonably necessary" and sensitive information cannot be collected without "consent". In practice, they can simply refuse renting the property if you don't give what they want.
How should a privacy-aware individual rent a place? Is it better for privacy if one were to stay in a hostel? What are my options?
