Sega World Sydney

Sega World Sydney was an indoor high-tech amusement park that operated for almost four years, in Sydney. The theme park was built as the flagship tenant of the Darling Walk complex in Darling Harbour, and was designed and themed by gaming company Sega as one of several SegaWorld-branded amusement parks.

Land for the park was acquired by Jacfun Pty Ltd in 1994, with the amusement park opening in 1997. The remainder of the complex was sublet to a mix of retail and entertainment tenants. By 2000, Sega had pulled out from the partnership operating Sega World, and the park was suffering from low attendance and financial losses. There were hopes that tourists visiting Sydney for the 2000 Summer Olympics would help meet the visitor breakeven point, but this did not occur, and Sega World closed in November 2000. The rides were auctioned off in 2001.

Jacfun attempted to find a new tenant to replace Sega World, but the restrictive zoning meant that more profitable revenue streams (such as office-space) were unusable. In 2003, Jacfun sold its lease of the Darling Walk site back to the Sydney Harbour Foreshore Authority, with the lease to terminate in 2008. The site was leased to Lend Lease in 2008, with the Darling Walk building demolished and replaced with the new Commonwealth Bank of Australia global headquarters.

Sega World history
In 1994, Jacfun Pty Ltd acquired a 90-year lease for land in the Darling Harbour precinct from the Sydney Harbour Foreshore Authority. The location, which became the Darling Walk, was zoned for entertainment use.

Jacfun, in collaboration with Sega and the Darling Harbour Authority, invested A$80 million to build Sega World Sydney, which opened in March 1997. Sega World Sydney utilised the latest in multimedia, entertainment and destination attraction events. It was described as "Australia's Interactive Disneyland" by the media. Many of the themes were based on various Sega franchises, primarily Sonic the Hedgehog. The park was also host to underage dance parties called Crush, usually held during school holidays. The remainder of the complex was sublet to a mix of retail and entertainment tenants.

Due to a below-expected attendance and constant financial losses, the park was closed in November 2000. Hopes that the influx of tourists travelling to Sydney for the 2000 Summer Olympics would help the park meet its 800,000-visitor breakeven point went unrealised. Sega had sold its stake in the park to Jacfun in 1999, for A$36 million. In March 2001, the contents of the park were auctioned off. Only 300 people attended the auction, with most of the rides sold off for minimal prices. The two major rides of the park, Rail Chase and Ghost Hunters, were sold to foreign buyers, with one of the rides going for A$60,000 less than its intended sale price of A$200,000. Some of the amusement park's interior fixtures were still in place as of 2008, covered by backdrops and boarding.

Rides
As well as the rides, the park included a fast-food outlet and an extensive coin-op video arcade, featuring over 100 arcade games. This area was converted to free operation at a point in early 2000, prior to the closure.
 * Rail Chase – An indoor mine train roller coaster built by Masago Industrial with elaborate scenery and theming. After the closure of Segaworld, the ride was sold to Haailand where it remains in operation.
 * Mad Bazooka – A 'tank simulator' built by R & T Fabrications, with modified bumper cars equipped with a ball cannon. Balls were collected from the floor of the arena by running over them, and then could be fired at targets mounted to the roofs of other cars. The ride was removed in 1999 to make way for an ice rink.
 * Ghost Hunters – An interactive ghost train, with riders provided with laser cannons to shoot targets. see Shooting dark ride. Was also sold to Haailand.
 * Magic Motion 4D – A 4-D cinema.
 * Nickelodeon TV Machine – A children's play area themed on the TV channel Nickelodeon, which included activities based on the famous green slime and featured a climbing jungle, ball pits, and a spiral slide. Rocko was a prominent character in the area, due to the park being located in Australia.
 * Aqua Nova – A 3-D motion simulator themed around a submarine on an underwater mission.
 * AS-1 – A motion simulator ride depicting the futuristic chase of a criminal. The ride starred Michael Jackson as the spacecraft captain.

Sonic Live in Sydney
A 1½ hour live show hosted at the park, Sonic Live in Sydney, was set in an alternate timeline based around the Saturday morning Sonic animated series and the Sonic 3 video game. Doctor Robotnik's Death Egg crash-lands in Australia instead of Angel Island, causing the scientist to attempt a takeover of Sydney, which is foiled by Sonic, Tails, and Sally Acorn at the end of the show. A subplot of this show involved Tails being shown around Sydney's landmarks. There was a large amount of audience interaction in the show.

Most of the music (as well as sound effects) for the show was taken from Masato Nakamura's score on Sonic The Hedgehog 2, with three theme pieces; Sonic's "What Are We Waiting For", Dr. Robotnik's "Give Me Chaos" and "Thank You For Being You" sung by Sally Acorn. A recording without audience was made of the performance.

This performance is notable for having one of the only times Sonic has had a female voice actor, another notable example being Sonic's Schoolhouse. This was also the first time Tails had a female English voice actor, which would become common practice starting with Shadow the Hedgehog.

Other tenants and post-Sega World history
Shortly after Sega World closed, the two other major tenants of the Darling Walk complex, the Daintree Cafe and the One World Sports restaurant and bar, also closed. Jacfun planned to install an entertainment complex to replace Sega World, as the restrictions of the "entertainment use" zoning prevented Jacfun from exploring other options, such as replacing the building with offices. In March 2003, unable to find a new flagship tenant and losing money, Jacfun sold the lease for the Darling Walk site back to the Sydney Harbour Foreshore Authority for A$10 million, with the lease set to expire in June 2008. Around May 2006, the only tenant was a McDonald's restaurant, although the former Sega World site saw use as a furniture exhibition warehouse. From June 2006 to June 2007, the former One World Sports area was used as the house for MTV reality television series The Real World: Sydney.

In 2008, the SHFA leased the Darling Walk site to Lend Lease for A$560 million, which planned to demolish the building and erect two nine-storey office blocks for the Commonwealth Bank. This development was permitted by the changing of the zoning affecting the site, which had occurred shortly before the lease's signing. The old building demolished during October and November 2008. In March 2009, Jacfun initiated legal action in the New South Wales Supreme Court against the Sydney Harbour Foreshore Authority for "deceptive conduct" and claiming a share of the redevelopment's profits. A clause in the 2003 sale of Jacfun's lease back to the SHFA stated that if the Darling Walk site was resold within five years for more than A$40 million, a share of the profit would be forwarded to Jacfun; the rezoning of the site (which made the subsequent resale feasible) occurred just after the five-year period expired, and Jacfun was alleging that this had been planned prior to their lease ending. On 25 July 2012, the New South Wales Court of Appeal ordered the Sydney Harbour Foreshore Authority to pay $1.2 million for the loss of its Jacfun's opportunity to negotiate a higher price for the surrender of the lease. In April 2018 it was discovered that a Sonic and Sally statue, a smaller version of the iconic statue that stood outside of the building, had turned up at a junkyard in Londonderry in Sydney's north west. The junkyard also houses two entry way signs from another former Sydney theme park in Wonderland.
