Season 3 of the Australian version of the The Masked Singer premiered on September 13, 2021 and concluded on October 5, 2021.
The third season was filmed with a hybrid of in-studio and virtual audience between July 3 and July 24, 2021. As a result of the COVID-19 pandemic and lockdown restrictions in Australia, the in-studio audience consisted of socially-distanced production staff wearing costumes, just like in Season 2.
100 Australian viewers were selected to be part of the virtual audience. They streamed the live performances and voted for their favourite character's performance. For confidentiality, the virtual audience did not witness the elimination's result or the unmasking of the performers.
