Eerie music plays and a grim reaper awaits as excited riders are ushered down a hallway to the sinister black carriages of The Abyss.
Adventure World's new $12 million roller-coaster has been described as "smooth, fast and better in the dark".
For the first few people to test the ride, the fear factor was almost as high as the excitement of knowing they would soon be zipping around at up to 85km/h.
The ride's biggest surprise hits as the journey begins.
Excited riders are plunged into a hidden "dark section" with a sudden drop, twists, turns and a nauseating upside down flip.
The carriage then heads skywards and slows just enough for a clear view of the sky before the most feared section, a 35m vertical drop.
A slow climb to the top and a graceful "rainbow" motion allows just enough time to admire the whizzing traffic beyond the gates before the carriage plunges fast enough to silence most screaming thrillseekers.
The Abyss designers have allowed just enough sudden movement in the final section to give riders sea legs as they are thrown around at speed for a final time in full view of spectators.
After about two minutes, The Abyss rolls to a halt in the loading bay to a chorus of laughs and excited voices - and those who dare head straight for a second blast.
