Reserve Bank of Australia Building, Sydney

The Reserve Bank of Australia (RBA) is Australia's central bank and banknote issuing authority. It has had this role since 14 January 1960, when the Reserve Bank Act 1959 removed the central banking functions from the Commonwealth Bank.The bank has the responsibility of providing services to the Government of Australia in addition to also providing services to other central banks and official institutions. It currently consists of the Payments System Board, which governs the payments system policy of the bank, and the Reserve Bank Board, which governs all other monetary and banking policies of the bank.Both boards consist of members of both the bank, the Treasury, other Australian government agencies, and leaders of other institutions that are part of the economy. The structure of the Reserve Bank Board has remained consistent ever since 1951, with the exception of the change in the number of members of the board. The governor of the Reserve Bank of Australia is appointed by the Treasurer and chairs both the Payment Systems and Reserve Bank Boards and when there are disagreements between both boards, the governor resolves them.From the middle of the 19th century into the 1890s, the prospects for the forming of a national bank grew. In 1911, the Commonwealth Bank was established, but did not have the authority to print notes, which was a power that was still reserved to the Treasury. A movement toward reestablishing the gold standard occurred after World War I, with John Garvan leading various boards in contracting the money supply on the route to doing so, and the gold standard was instituted for both the British pound sterling and the Australian pound in 1925.During the Great Depression, the Australian pound became devalued, no longer worth the same as the pound sterling, and formally departed from the gold standard with the Commonwealth Bank Act of 1932. Legislation in 1945 led to regulation of private banks which Herbert Coombs was opposed to, and when he became governor in 1949, he gave them more overall control over their institutions. When the monetary authorities implemented the advice of Coombs to have a flexible interest rate, it allowed the bank to rely more on open market operations. In 1980 the issue of short-term government bonds – Treasury notes of 13 and 26 weeks duration – changed from a tap system, in which the price was set, to a tender system in which the volume of stock was set and the price determined by the market. Soon afterwards the tender system was extended to the issue of longer-term government bonds. The float of the Australian dollar happened in 1983, around the same period of time that the financial system in Australia was deregulated. Administration of the banks was transferred in 1998 from the bank to the Australian Prudential Regulation Authority and the Payments System Board was created, while the bank was given power within the board in the same year. The current governor of the Reserve Bank is Philip Lowe, who succeeded Glenn Stevens as governor on 18 September 2016.In May 2022, the bank increased the nation's interest rates for the first time in more than a decade. This move was designed to combat the inflation, right before the election that is heavily focused on increased costs of living.

The Sydney central business district (CBD) is the historical and main commercial centre of Sydney. The Sydney CBD is Sydney's city centre, or Sydney City, and the two terms are used interchangeably. The CBD or city centre is often referred to simply as "Town" or "the City". The Sydney city centre extends southwards for about 3 km (2 mi) from Sydney Cove, the point of first European settlement in which the Sydney region was initially established. Due to its pivotal role in Australia's early history, it is one of the oldest established areas in the country. Geographically, its north–south axis runs from Circular Quay in the north to Central railway station in the south. Its east–west axis runs from a chain of parkland that includes Hyde Park, The Domain, Royal Botanic Gardens and Farm Cove on Sydney Harbour in the east; to Darling Harbour and the Western Distributor in the west. At the 2016 Australian Census, the City recorded a population of 17,252.The Sydney City is Australia's main financial and economic centre, as well as a leading hub of economic activity for the Asia-Pacific region. The city centre and areas immediately around it employ approximately 22% of the Sydney region's workforce. The City has the largest gathering of workers in the whole of Sydney. Most of them are white collar office workers in the finance and professional service industries. In 2012, the number of workers operating in the City was 226,972. Based on industry mix and relative occupational wage levels it is estimated that economic activity (GDP) generated in the city in 2015/16 was approximately $118 billion. Culturally, the city centre is Sydney's focal point for nightlife and entertainment. It is also home to some of the city's most significant buildings and structures.

The Lindt Cafe siege was a terrorist attack that occurred on 15–16 December 2014 when a lone gunman, Man Haron Monis, held hostage ten customers and eight employees of a Lindt chocolate café in the APA Building in Martin Place, Sydney, Australia. The Sydney siege led to a 16-hour standoff, after which a gunshot was heard from inside and police officers from the Tactical Operations Unit stormed the café. Hostage Tori Johnson was killed by Monis and hostage Katrina Dawson was killed by a police bullet ricochet in the subsequent raid. Monis was also killed. Three other hostages and a police officer were injured by police gunfire during the raid.Police have been criticised over their handling of the siege for not taking proactive action earlier, for the deaths of hostages at the end of the siege, and for the lack of negotiation during the siege. Hostage Marcia Mikhael called radio station 2GB during the siege and said, "They have not negotiated, they've done nothing. They have left us here to die."Early on, hostages were seen holding a Jihadist flag against the window of the café, featuring the shahādah creed. Initially, many media organisations mistook it for the flag used by the Islamic State (IS); Monis later demanded that an IS flag be brought to him. Monis also unsuccessfully demanded to speak to the Prime Minister of Australia, Tony Abbott, live on radio. Monis was described by Abbott as having indicated a "political motivation," but the eventual assessment was that the gunman was "a very unusual case—a rare mix of extremism, mental health problems and plain criminality."In the aftermath of the siege, Muslim groups issued a joint statement in which they condemned the incident, and memorial services were held in the city at the nearby St Mary's Cathedral and St James' Church. Condolence books were set up in other Lindt cafés and the community turned Martin Place into a "field of flowers." The Martin Place Lindt café was severely damaged during the police raid, closed afterwards, then renovated for reopening in March 2015.
