As first revealed in official teaser trailers last month, a road accident will lead to heartbreak and horror in Summer Bay in scenes which are about to air on Australian screens.
Exact information over who will be involved - and injured - in the crash is still being kept tightly under wraps. However, it has been confirmed that the dramatic incident is caused by a brake problem, which results in the vehicle coming off the road and into a field in explosive stunt scenes.
Rebecca Breeds, who plays Ruby Buckton, told TV Week: "There are a lot of cliffhangers in Home and Away and you can't compare them, but obviously Charlie's death was out of this world and I was really involved in that one, but this one is also huge in a different way.
"It's completely shocking on all levels and there will be a lot of mixed responses from the fans about what happens."
Charles Cottier, better known as Dexter Walker, added: "There's a problem with the brakes, they seem to have disappeared - and the car careens out of control off the side of the road, flips five times and ends up upside down, pretty damaged.
"It's one of the biggest storylines that has happened since I've been on the show. It affects everyone. Every character on the show is talking about it, so it affects everyone in different ways."

Once the driver has been rushed to hospital, his or her loved ones are soon given alarming news.
Cottier continued: "There's a lot of bruising and broken ribs, but the main injury is a brain injury. It's devastating for all of them and they desperately want this person to get through. There are lots of tears and heightened emotions and some breakdowns."
Whether the individual will survive will not be confirmed until transmission, but Breeds teased: "There will be a lot of people who care about this character and it will be devastating for all."
Home and Away airs these scenes next week on Network Seven in Australia, and in October on Channel 5 in the UK.
