Abyss is a steel roller coaster located at the Adventure World amusement park in Perth, Western Australia.

The Abyss is a Euro-Fighter, a roller coaster model from Gerstlauer that features a "beyond-vertical" first drop which exceeds 90 degrees.

In addition to several inversions, the Abyss reaches a top speed of 85 kilometres per hour (53 mph) along the two-minute, 630-metre-long (2,070 ft) ride.

[6][7] Abyss officially opened to the public on 1 November 2013 as the single biggest investment in the park's history.

[6][13] The two-minute ride features a top speed of 85 kilometres per hour (53 mph) and exerts up to 4.5 times the force of gravity on its riders.

The train emerges from the show building and makes a slight left towards the 30-metre (98 ft) chain lift hill.

An air-time hill, where riders experience the feeling of weightlessness, and a right turn leads into the mid-course brake run.

[15] Natalie Bonjolo of Today Tonight stated she didn't "know whether to laugh or cry" at the end of Abyss, describing the ride as unbelievable.
