Friend Bee Doyle told The Daily Telegraph: "I just saw the wonderful footage that Elly has escaped or has been released. Gosh what a relief".
Her sister Nicole Chen posted her relief on Facebook. "Yessss I finally see you. I'm so glad you're safe!!!!"
On top of her work as a Lindt Cafe barista, where she is renowned for her warm, smiling service, the Granville resident is a current student at NSW University and a former ace student of Presbyterian Ladies College.
Moments after the horror unfolded in the popular chocolate cafe, Ms Chen's hands were pressed up against its window, grasping a sign with Islamic script: "There is no god by Allah. And Muhammad is his messenger."
Her eyes closed. Her legendary smile, replaced by the unfathomable fear and anxiety, her fate in the hands of a terrorist.
Friends on social media posted the photo in disbelief, asking the question, hoping for a different answer.
"Elllyy?!!!! Please don't be true!!!! Making so many prayers it's not xxx" Bee Doyle posted.
"Fkkk im so worried about you atm! Please be safe!! Work told me not to come into martin place atm but mitch and nick swear they saw you cause I know you're working at lindt today!" her fellow Lindt employee Nicole Chang said.
