The Big Brother Audition Process

The most important thing to remember is that thousands of potential housemates will apply to be on Big Brother Australia and we value every single application we receive.

Unfortunately, there are only a limited number of places available on the show - so don't be disappointed if your application is not successful this time.

What happens from here?

Once you've submitted your application, you MAY receive a phone call from our casting department. They will want to conduct a phone chat to get to know a little more about you. Please note. not all applicants will be contacted by our casting department.


THE ONLINE APPLICATION

The application is split into a series of sections and questions and will take approximately 15-20 minutes to complete. You will also need to film and upload a short video to demonstrate your personality and what it is about you that makes you a great potential housemate.

The closing date for applications is 9am on Monday the 1st of September 2025 (Sydney/Eastern Standard Time). 

Please note - the sooner you complete your application the better!

Please do not contact the casting department to check on the status of an application.

The casting team will contact you if they require any additional information.

Once you have registered, you may return at any time before the closing date to complete your application. Make sure you record your login details in order to re-access your application form. Your application will only be submitted once you have agreed to the terms and conditions.
