Executives decided not to renew the contracts of Nell Feeney, who plays Janelle, and Sianoa Smit-McPhee, better known as Bree, following the departures of Ben Nicholas (Stingray) and Damien Bodie (Dylan).
The actresses leave screens in Australia next month, but Smith - who plays Harold Bishop - does not agree with the decision.
"I think it was a huge mistake to get rid of them - I was in love with every single one," Ian told Inside Soap.
"Fortunately, we're still left with Janae, played by Eliza Taylor-Cotter. If you want an actress who's going places, look to her. She's a natural-born comedienne and a lovely person, too. If I could have been guaranteed of having a child like her in real life, I might have considered it."
