New South Wales Urban Search and Rescue Task Force 1 (or NSWTF/1) was first established as a USAR capability in the lead up to the 2000 Sydney Olympics.
 After earlier large-scale collapses including the 1977 Granville Train Disaster, 1989 Newcastle earthquake and 1997 Thredbo landslide, Fire & Rescue NSW was legislated as the combat authority for responding to major structural collapse incidents within the state of New South Wales.
Sir Alister Maxwell McMullin, {'1': ", '2': ", '3': ", '4': "} (14 July 1900 – 7 August 1984) was an Australian politician.
 Born in Scone, New South Wales, he was educated at state schools before becoming a farmer and grazier.
 He served in the Royal Australian Air Force in 1940-1945, and when he returned served on Upper Hunter Shire Council.
 In 1951, he was elected to the Australian Senate as a Liberal Senator for New South Wales.
 In 1953, he succeeded Ted Mattner as President of the Senate; he served as President for 18 years, until his retirement from the Senate in 1971.
 He is thus the longest serving President of the Senate in Australian history.
The Granville rail disaster occurred on Tuesday 18 January 1977 at Granville, a western suburb of Sydney, Australia, when a crowded commuter train derailed, running into the supports of a road bridge that collapsed onto two of the train's passenger carriages.

Airlines of New South Wales (also known as Air New South Wales, Ansett NSW and Ansett Express) callsign "NEWSOUTH" was an Australian domestic regional airline that operated from 1959 until its merger into Ansett in 1993.
 It was formed by Reg Ansett's takeover of Butler Air Transport.
 Airlines of New South Wales operated air passenger services in New South Wales, and later in other Australian states.
 In 1964–65 the airline fought a High Court case, Airlines of New South Wales Pty Ltd v New South Wales (No 2), that was significant in adjudicating the spheres of constitutional power of the national and state governments in respect of air navigation.
Rail Corporation New South Wales (RailCorp) is a State-owned corporation of the State of New South Wales, Australia established under the "Transport Administration Act 1988" in 2004.

The Street family is the only dynasty in Australian history with three consecutive vice-regal appointments to their name; Sir Philip Whistler Street, his son Sir Kenneth Whistler Street and his grandson Sir Laurence Whistler Street all having become Chief Justices of the Supreme Court of New South Wales and Lieutenant Governors of New South Wales.
 The appointment of Sir Kenneth as a judge of the Supreme Court on 7 October 1931 also made Australian history, and potentially global history, for the first and only time a father and son have sat on the same bench as judges together, his father Sir Philip having been Chief Justice at the time.
 The narrator of the ABC series "Dynasties" said: "Among the great and powerful of the law, no family sits higher than the Streets.
 They've been at the forefront of the legal establishment for over a century."
The 1993 Big Bayou Canot train wreck was the derailing of an Amtrak train on the CSXT Big Bayou Canot bridge in southwestern Alabama, United States, on September 22, 1993.
 It was caused by displacement of a span and deformation of the rails when a tow of heavy barges had collided with the bridge eight minutes earlier.
 Forty-seven were killed and 103 were injured.
 To date, it is both the deadliest train wreck in Amtrak's history and the worst rail disaster in the United States since the 1958 Newark Bay, New Jersey rail accident in which 48 lives were lost.
The Government of New South Wales, also referred to as the New South Wales Government or NSW Government, is the Australian state democratic administrative authority of New South Wales.
 The Government of New South Wales, a parliamentary constitutional monarchy, was formed in 1856 as prescribed in its Constitution, as amended from time to time.
 Since the Federation of Australia in 1901, New South Wales has been a state of the Commonwealth of Australia, and the Constitution of Australia regulates its relationship with the Commonwealth.
 Under the Australian Constitution, New South Wales ceded legislative and judicial supremacy to the Commonwealth, but retained powers in all matters not in conflict with the Commonwealth.
