United Development Sydney (UDS) Pty Ltd - ACN 614 991 730 respects the privacy and security of your Personal Information, as defined below, and complies with the requirements of the Australian Privacy Principles (“APP”) under the Privacy Act 1988 (Cth) (“the Act”).

This Privacy Policy explains in general terms how UDS handles your Personal Information. However, it does not apply to UDS’s employee records in relation to the employee's current or former employment. Such employee records are generally exempt from the Act and will be dealt with as permitted by law. 

You may be able to deal with us without identifying yourself (i.e. anonymously or by using a pseudonym) in certain circumstances. If you wish to do so, please contact us to find out if this is practicable in your circumstances. However, if you do not provide us with the Personal Information we have requested, we may not be able to complete or fulfil the purpose for which we collect the information, including providing our services. 

By visiting our websites, using any of our services or otherwise providing us with your Personal Information (or authorising it to be provided to us by someone else), you agree to your Personal Information being collected and handled as set out in this Privacy Policy. 


Under the Act Personal Information is defined as information or an opinion about an identified individual, or an individual that is reasonably identifiable, in whatever form and regardless of whether it is true or not (‘Personal Information’). The Act also defines a subset of Personal Information as sensitive information (for example health records, racial or ethnic origin, religious beliefs, criminal records). 

The types of Personal Information we collect, and hold will depend on the circumstances of collection and on the type of service we are providing. For example, when you purchase a property, we may collect and hold Personal Information from you such as name, address, email address, telephone numbers and if applicable details about your business.

We may also collect and hold certain sensitive information that is reasonably necessary for the provision of our services, including health and criminal records. If you provide us with any sensitive information, you consent to us collecting that information and handling it in accordance with this Privacy Policy


We may collect Personal Information about you directly when you deal with us over the telephone, send us correspondence (whether by letter or email), have contact with us in person, visit our websites or complete hard copy or online forms.

Depending on the type of service you have requested, we may also seek to collect information about someone else from you (for example, contact details of your solicitor or emergency contact person). However, you must not provide us with Personal Information about another person unless you have clear consent from that person to do so, told them that their Personal Information will be handled in accordance with this Privacy Policy and directed them to where they can find it. 

Regardless of how it is collected, we handle Personal Information in accordance with this Privacy Policy. 


We generally collect, hold and use your Personal Information for the purposes for which it is provided to us (which will usually be obvious at the time of collection), related purposes or as permitted or required by law. Such purposes may include:


We may disclose your Personal Information to third parties as may be necessary for any of the purposes stated in the above section. Such third parties generally include:

There is no charge for making the request. We will deal with your request within a reasonable period after the request is made.

If we refuse to provide you with access, we will provide you with a written notice that, at a minimum, outlines reasons for the refusal and the complaints mechanisms available to you.

We take reasonable steps to protect any Personal Information that we hold from misuse, interference and loss and from unauthorised access, alteration and disclosure. 

However, data protection measures are never completely secure and, despite the measures we have put in place, we cannot guarantee the security of your Personal Information.
