DID YOU MISS A CALL FROM ONE OF OUR NUMBERS?Our staff may have contacted you,

to be part of a research survey!

We may have contacted you by phone,
text message, email or sent you a letter.


We are a market and social research company and are not covered by the Australian Do Not Call Register because we are not selling a product, your participation in a survey is always voluntary, and we will not provide your name or contact information to any other parties unless you ask us to and authorise us to do this. Some people do not wish to participate in any surveys, and to respect that point of view we have developed our own internal do not call register. We will add you to that if you ask us to by contacting us or ask us to when we contact you. If you are added to the Wallis do not call register, Wallis will not contact you again for any research that we are conducting, even if your name is on a listing supplied to us by a company whose service you use. However, being on our do not call register does not preclude you from being contacted by other research agencies.

If you would like to be added to our internal do not call register please let us know via our contact us form here

Wallis Market and Social Research knows how important your privacy is. If we send you a text message it will be using a secure Australian service.

We allocate specific e-mail addresses to different projects, but all of the addresses end in @wallisgroup.com.au


Wherever possible we will send you a letter with details about the study. This will always have our address and/or that of our clients on it.  Our street address is Level 2, 273 Camberwell Road, Camberwell VIC 3124.

You can always call us on to check on any information or click here to see a list of current research studies on this website. Our main phone number is 03 9621 1066. This is always answered personally from 8.30am – 5.30pm Monday to Friday and usually at weekends from 10am – 5pm.

Protecting your data and your privacy is extremely important to us

In 2018 the law changed to make it compulsory for any companies that mishandle personal information to tell the people affected and in serious cases to report this to the Office of the Australian Information Commissioner.

Wallis goes one step further and guarantees that it will tell any organisation or individual if it has mishandled their data – this includes business information (not covered by law). We introduced mandatory reporting in 2015. Wallis is a member of the Association of Market and Social Research Organisations (AMSRO). We are bound to comply with even stricter legislation than the Privacy Act (1988) and members also guarantee that they are quality certified and working to the industry’s Code of Professional Behaviour. More information about AMSRO is available here.
