Danni Minogue guessed Pav was an incognito Isla Fisher, Dave "Hughesy" Hughes took a stab at Natalie Portman, Urzila (who was very adamant that a Pav originates from NZ rather than down under) guessed it was Kiwi musician Lorde, and Jackie O suggested it might be Home & Away alum, Melissa George.
Twitter, however, had other ideas as to the Pavlova's true identity. Take a look.
Some top contenders when it came to guessing were The Great Australian Bake Off's Claire Hooper and comedian Kitty Flanagan, who both lived in WA for a time.
Meanwhile, many viewers believed Aussie cook and musician Anna Gare was behind the mask. A cook born in Western Australia who began her music career when she was 12 - she certainly seemed to fit the criteria.
So, are any of these guesses correct? We'll just have to keep watching for more clues.
