Esther's character Charlie was a fan favourite who left the show in tragic circumstances earlier this year. Exact details of her return are kept under wraps.
"It was a shock and a surprise to get the call, but I said yes straight away; the chance to come back and work on the show was an opportunity I didn't have to think too hard about at all!
Charlie holds a very special place in my heart and I'm so grateful for the support I have received from Home and Away fans" said Esther.
While we can't reveal Esther's storyline, it will include Steve Peacocke and that wonderful Charlie/Brax chemistry.
2013 will be a fantastic year for Home and Away, stay tuned!
