The actor, 44, has played beloved character Jarrod "Toadie" Rebecchi since he was brought in as a guest in January 1995.
In a video shared on social media, Maloney introduced himself as "Formerly Jarrod 'Toadfish' Rebecchi from Neighbours", before explaining: "That's right, I did say formerly, because after 30 years of playing Toadie, I will be leaving Ramsay Street."
Toadie has been on an emotional journey this season, but what's next for him? — Neighbours (@neighbours) Here's a message from Ryan...@AmazonFreevee @Channel10AU @Goldupslane pic.twitter.com/yO0oUayuWsJune 27, 2024
He said: "I can't tell you what is going to happen to the character, whether or not we are going to see him again. Maybe I could be the next Jim Robinson and just..." before clutching his chest to imitate the heart attack Jim's character suffered back in 1993.
"Or maybe I'll be the next Harold Bishop and just keep popping back over the years."
Maloney, who is embarking on a live show called Toad on the Road, said he would not be leaving Neighbours behind altogether and will be heading behind the camera to work as a director.
"Although I won't be bringing you our fantastic storylines from in front of the camera, I do hope to be bringing them to you from the other side, behind the camera," he said.
"Before I go, I would just like to take the opportunity to say thank you all so much for all the love that you have shown me and Toadie over the years, for three decades, in fact.
"I'm going to miss you and I'm going to miss him, and I'm going to miss Erinsborough.
"But whatever you do, make sure you do not miss what is going to happen on Ramsay Street."
Toadie first appeared on the soap as a teenager and was never planned to be a long-running character.
He is the second longest-running continuous character on the show after Karl Kennedy, played by Alan Fletcher.
Neighbours airs on Network Ten in Australia and on Amazon Freevee in the UK and US.
