The comedy actress made the decision after watching a marathon of MTV show Catfish.
The Australian star wrote on Twitter: "I would never online date unless it was for 'comedy research'. The other things I've done for 'comedy research' include fat camp and drinking."
The TV show follows young people as they meet their online lovers for the first time, and was inspired by the 2010 documentary starring Nev Schulman.
In a series of online posts on January 17, the 26-year-old admitted to watching "like six episodes" of the "addictive" programme.

The Pitch Perfect star said: "That Catfish show is so funny and yet so sad at the same time. Kinda fascinating. Just watched the original [documentary] and it's awesome!"
The single star called the series a "very fascinating character study" and added she "can't believe these people do this".
She added: "Catfish teaches you to Google image search. Always!"
