Fish, who plays April Scott, has hinted at plans to depart the long-running show in favour of new acting projects.
The 22-year-old told TV Week: "I've got something that is in the works in Australia, but then I'm heading over to Los Angeles next year. It's exciting and I want to do something that makes me nervous and puts me on my toes again.
"I'm just so happy to have had this experience and now be going on to something different."
On saying goodbye to the Home and Away team, she added: "They become your family, so it will be very sad."
Fish today (April 15) followed up her interview by tweeting that she has no plans to leave "anytime soon". However, departing Home and Away cast members often deny reports of their exits to keep fans guessing.

Younes, who plays Casey Braxton, has also indicated that he is considering his future at Home and Away after seeing a number of his former colleagues move over to Hollywood.
He told TV Week of his US ambitions: "After Home and Away, I'd love to go. LA is kinda the next thing to do, but I'd also love to do some Australian stuff - maybe a film or some theatre.
"I'm going over to LA this year and I'll hang with Luke [Mitchell], David [Jones-Roberts] and Axle [Whitehead], just to see what it's like and whether I like it.
"When the Braxtons do leave, it's going to be quite odd. I love that people love the characters, but I'm sure there will be many new faces viewers will love even more."
Home and Away airs weekdays at 1.15pm and 6pm on Channel 5 in the UK, and weekdays at 7pm on Network Seven in Australia.
