Project Zero is a Maurer Rides sit-down roller coaster currently located at Gumbuya World in Tynong, Victoria, Australia. It was previously located at Dreamworld in Coomera, Queensland, where it operated as BuzzSaw.


BuzzSaw opened at Dreamworld on 17 September 2011.

In July 2021, Dreamworld announced that BuzzSaw would close on 31 August.[1] The ride was dismantled in November 2021.[2] It was later sent to Gumbuya World.[3]

The ride reopened as Project Zero at Gumbuya World on 23 December 2022.[4]


The ride began with a vertical lift hill leading out of the station. Upon reaching the top, rather than leveling off at 0° like most roller coasters, it leveled off in the opposite direction, turning riders upside-down. The train then traveled through a barrel roll which led into the vertical drop back into the station. Continuing through the station, the ride traveled back up the lift hill, before losing momentum and traveling backwards through the ride. It then lost momentum in the opposite direction and traveled back into the station. This process was completed twice during the duration of the ride.


Single train with 2 cars. Riders are arranged 2 across in 3 rows for a total of 12 riders.
