58 free Sydney Opera House trivia questions with answers — geography quiz, new questions added Aug 2026.
The Sydney Opera House took sixteen years and fifteen times its budget to build, and its architect never saw it finished. This quiz covers the whole saga: the conductor who insisted on Bennelong Point, the 233-entry competition Eero Saarinen helped judge, the spherical geometry that finally made the sails buildable, the Swedish tiles, the 1966 resignation and 'Malice in Blunderland', Peter Hall's rescue of the interiors, and Queen Elizabeth II's opening in 1973. The building's afterlife is here too: Paul Robeson singing to the construction crew, Prokofiev on opening night, Thin Lizzy on the steps, Arnold Schwarzenegger's last title, Nelson Mandela's crowd of 40,000, the 'No War' paint job, Vivid, the horse-race petition and the 50th birthday. Easy questions suit anyone who has seen a postcard; the hard ones cover granite quarries and the Gadigal name for the point. Every answer was checked against Wikipedia's articles on the Opera House, Jørn Utzon, Bennelong Point and Ove Arup, and the supporting sentence is attached to each question. For the city itself, try our Sydney quiz.

Q 01Which Danish architect designed the Sydney Opera House?
Jørn Utzon
Jørn Utzon won the 1957 design competition but resigned in 1966 after months of hostility from a new state government, leaving other architects to complete the interiors.
Q 02Who formally opened the Sydney Opera House on 20 October 1973?
Queen Elizabeth II
Queen Elizabeth II opened it without its architect present: he was invited but declined, writing that he could not be the government's guest while criticising one of its ministers.
Q 03In 1999 the Opera House's original architect agreed to produce what?
Design principles
Design principles ended a 33-year rift: they were written to guide later changes to the building, and the first room rebuilt to his design reopened in 2004 under his name.
Q 04On which headland of Sydney Harbour does the Opera House stand?
Bennelong Point
Bennelong Point honours Woollarawarre Bennelong, a Wangal man kidnapped on the governor's orders in 1789 who became a go-between with the colonists and later sailed with him to England.
Q 05Until a channel was filled with rock in the early 1800s, Tubowgule, the Opera House's site, was what kind of landform?
A tidal island
A tidal island: high water cut it off from the shore, and the colonists burned its heaps of oyster shells, left by generations of Gadigal meals, to make lime for their first buildings.
Q 06What did Governor Phillip build in 1790 on the Opera House's headland for the Aboriginal man it is named after?
A brick hut
A brick hut, built at his request: the Wangal man had become the governor's go-between with the Eora, and in 1792 he sailed with him to England, among the first Aboriginal people to make the voyage.
Q 07What building was demolished in 1958 to clear the site for the Opera House?
A tram depot
A tram depot stood there, built in 1902 with mock battlements in homage to Fort Macquarie, the colonial fort it had replaced; the depot closed in 1955.
Q 08Which Sydney Symphony conductor lobbied for the Opera House and its harbourside site?
Eugene Goossens
Eugene Goossens campaigned for the hall and suggested its harbour site, but a 1956 scandal over indecent photographs found in his luggage forced him to resign and leave Australia before a design was chosen.
Q 09Which New South Wales premier launched the Opera House design competition and authorised its construction?
Joseph Cahill
Joseph Cahill had work begin in March 1959, before the design was finished, fearing that opponents might kill the project if he waited; he died in office seven months later.
Q 10Which ancient civilisation's temple platforms, seen by the architect on his travels, inspired the Opera House's massive raised base?
The Maya
The Maya: in Mexico he was struck by how their stone platforms lifted people above everyday life and toward the sky, and he gave Sydney's concertgoers the same climb.
Q 11Which Finnish-American architect on the Opera House competition jury championed the winning design?
Eero Saarinen
Eero Saarinen missed the start of judging; in a widely told story that a fellow juror later disputed, he pulled the winning scheme from a pile of rejects and declared it the clear winner.
Q 12The Opera House's roof shells are all cut from the surface of which shape?
A sphere
A sphere: because every shell shares one curve, ribs of different lengths could be cast in the same moulds, ending years of failed schemes based on parabolas and ellipses.
Q 13What bonded the Opera House's precast roof segments?
Epoxy glue
Epoxy glue: the builders' engineers pioneered using resin to bond the precast units, and the roof proved the method for later concrete structures.
Q 21The original architect's own 2004 tapestry in the Opera House honours which composer?
Carl Philipp Emanuel Bach
Carl Philipp Emanuel Bach is honoured in the 14-metre tapestry, woven in Melbourne for the first room rebuilt to the architect's own design, nearly forty years after he walked away from the interiors.
Q 22How did New South Wales raise most of the money to build the Opera House?
A state lottery
A state lottery: rather than draw on taxes, the government sold Opera House Lottery tickets from the late 1950s, and gamblers ended up covering most of the bill.
Q 23First estimated at $7 million, what was the Opera House's final bill?
$102 million
Q 14Roughly how many tiles cover the Opera House's roof shells?
1 million
About 1 million: the 1,056,006 tiles were not laid one by one at height; they were set face down into curved panels on the ground, and the finished panels were lifted onto the shells.
Q 15The Opera House's roof tiles were manufactured in which country?
Sweden
Sweden: the Höganäs factory needed three years of development to get the finish the architect wanted, a glazed tile made of clay mixed with a little crushed stone.
Q 16Before he had ever visited Sydney, what did the Opera House's architect study to picture its harbour site?
Nautical charts
Nautical charts: he pored over maps of the harbour at his desk in Denmark, and first set foot in Sydney only after his design had already won.
Q 17The Opera House's base and broad walkways are faced with panels of crushed granite in which colour?
Pink
Pink: the precast panels are faced with granite quarried at Tarana, in central New South Wales, giving the building an earthy base that sets off its white shells.
Q 18Where did Sydney's orchestra play before the Opera House?
Town Hall
Sydney Town Hall: the orchestra's chief conductor complained that the 1889 hall was too small and could not stage opera, the grievance that launched the campaign for an opera house.
Q 19The Concert Hall's pipe instrument holds what world record?
Largest mechanical tracker-action organ
Largest mechanical tracker-action organ in the world: builder Ronald Sharp needed ten years, so the hall opened in 1973 without it and the instrument was not finished until 1979.
Q 20The Opera Theatre was renamed in October 2012 after which famous Australian soprano?
Joan Sutherland
Joan Sutherland, 'La Stupenda', sang her farewell opera at the Opera House in 1990, in Meyerbeer's Les Huguenots; the theatre took her name two years after her death in 2010.
$102 million was the total: the building had been promised for Australia Day 1963 and opened ten years late, at more than fourteen times its estimate.
Q 24Which Australian firm built the Opera House's roof shells, casting the concrete ribs in a factory on the site?
Hornibrook
Hornibrook's engineer Joe Bertony designed the movable steel arch that held each rib until a shell could stand, working out its stresses in some 30,000 calculations by hand.
Q 25Which engineering firm was the Opera House's structural engineer from 1957 until its completion?
Ove Arup & Partners
Ove Arup & Partners worked through at least a dozen roof schemes with the architect, and ran the shells' complex forces through some of the earliest computers used in structural design.
Q 26The 1965 election of which premier's government led to the Opera House architect's resignation a year later?
Robert Askin
Robert Askin had been a vocal critic of the project in opposition, and once he won office his works minister withheld the architect's fees until the Dane quit.
Q 27Which Minister for Public Works accepted the Opera House architect's resignation in 1966?
Davis Hughes
Davis Hughes withheld the architect's fees, and when the Dane threatened to quit at a meeting in February 1966 he took the threat as a resignation and had a replacement team in place within weeks.
Q 28Which Australian architect took over the Opera House's design and finished its interiors after 1966?
Peter Hall

Q 30Which opera was the first performed in the Opera Theatre, on 28 September 1973?
Prokofiev's War and Peace
Prokofiev's War and Peace got the honour by default: Peter Sculthorpe's Rites of Passage, commissioned for the opening, was not finished in time and premiered a year later.
