On Saturday, it was announced that stars of the Summer Bay show were due to arrive in Honolulu for "a full week of shooting".
At the time, Samara Weaving - who plays Indigo Walker on the programme - was the only cast member whose involvement had been confirmed.
However, a statement on Home and Away's official website has now named Luke Mitchell (Romeo Smith), Robert Mammone (Sid Walker) and Georgie Parker (Roo Stewart) as the other cast members who have travelled overseas for the special shoot.
Series producer Cameron Welsh commented: "We've got a great storyline and the locations we're shooting in are stunning - almost as good as Summer Bay.
"It's an exciting opportunity for the show to do something different and expand the stories we tell."
The episodes are due to air later this year.
