"An astrophysicist, the rose, the looking for love. Too obvious?" she pondered.
However Twitter blew up with many fans suspecting that the actor and musician Ben Lee is the elusive Professor.
Rather than being a symbol often associated with The Bachelor, the rose clue was also interpreted as a nod to Rose Byrne, Ben's co-star in 2003 film, The Rage in Placid Lake.
The actor also spent some time in South America, specifically Peru, where he experimented with psychedelic drug, ayahuasca. His upcoming album is even titled Ayahuasca: Welcome to The Work.
Other guesses include musical comedian Tim Minchin, TV and radio personality Dr Karl Kruszelnicki and another Bachelor, Matty J!
"Unfortunately it's not me, as much as I would like it to be me, it's not," Matty J confessed on his Instagram Stories the morning after the premiere before singing his rendition of Paul Kelly's Dumb Things which Professor belted on Monday night.
Guess we'll have to keep watching for more clues...
