<P> The men's singles rules have undergone several changes since the first edition . This event has always been contested in a knockout format, and all matches have been best - of - five sets except in 1970, 1973, and 1974, when the first round was best - of - three sets, and in 1982, when the third and fourth round were best - of - three sets . Since 1905, all sets have been decided in the advantage format . The lingering death best - of - twelve points tie - break was introduced in 1971 and has been used for the first four sets since then, except from 1980 to 1982, when the tie - break was also played in fifth sets . </P> <P> The champion receives a miniature replica of the silver - gilt Norman Brookes Challenge Cup, named after the 1911 champion and former Lawn Tennis Association of Australia (LTAA) president, and modeled after the Warwick Vase . In 2010, the winner received prize money of A $2,100,000 . </P> <P> In the Australasian Championships, James Anderson holds the records for most titles with three (1922, 1924--1925), and the most consecutive titles with two (1924--1925). In the Australian Championships, Roy Emerson holds the records for most titles with six (1961, 1963--1967) and most consecutive titles with five (1963--1967). The inclusion of professional tennis players in 1969 marked the competition's entry into the Open Era, in which Novak Djokovic (2008, 2011--2013, 2015--2016) and Roger Federer (2004, 2006--2007, 2010, 2017--2018) hold the record for most titles with six . The Open Era record for most consecutive titles is three by Djokovic (2011--2013). This event was won without losing a set during the Open Era by Rosewall in 1971 and Federer in 2007 . </P> <Table> <Tr> <Th> Year </Th> <Th> Country </Th> <Th> Champion </Th> <Th> Country </Th> <Th> Runner - up </Th> <Th> Score in the final </Th> </Tr> <Tr> <Td> 1905 </Td> <Td> AUS </Td> <Td> Heath, Rodney Rodney Heath </Td> <Td> AUS </Td> <Td> Curtis, Albert Albert Curtis </Td> <Td> 4--6, 6--3, 6--4, 6--4 </Td> </Tr> <Tr> <Td> 1906 </Td> <Td> NZL </Td> <Td> Wilding, Anthony Anthony Wilding </Td> <Td> NZL </Td> <Td> Fisher, Francis Francis Fisher </Td> <Td> 6--0, 6--4, 6--4 </Td> </Tr> <Tr> <Td> 1907 </Td> <Td> AUS </Td> <Td> Rice, Horace Horace Rice </Td> <Td> NZL </Td> <Td> Parker, Harry Harry Parker </Td> <Td> 6--3, 6--4, 6--4 </Td> </Tr> <Tr> <Td> 1908 </Td> <Td> USA </Td> <Td> Alexander, Fred Fred Alexander </Td> <Td> AUS </Td> <Td> Dunlop, Alfred Alfred Dunlop </Td> <Td> 3--6, 3--6, 6--0, 6--2, 6--3 </Td> </Tr> <Tr> <Td> 1909 </Td> <Td> NZL </Td> <Td> Wilding, Anthony Anthony Wilding </Td> <Td> AUS </Td> <Td> Parker, Ernie Ernie Parker </Td> <Td> 6--1, 7--5, 6--2 </Td> </Tr> <Tr> <Td> 1910 </Td> <Td> AUS </Td> <Td> Heath, Rodney Rodney Heath </Td> <Td> AUS </Td> <Td> Rice, Horace Horace Rice </Td> <Td> 6--4, 6--3, 6--2 </Td> </Tr> <Tr> <Td> 1911 </Td> <Td> AUS </Td> <Td> Brookes, Norman Norman Brookes </Td> <Td> AUS </Td> <Td> Rice, Horace Horace Rice </Td> <Td> 6--1, 6--2, 6--3 </Td> </Tr> <Tr> <Td> 1912 </Td> <Td> BRI </Td> <Td> Parke, James Cecil James Cecil Parke </Td> <Td> BRI </Td> <Td> Beamish, Alfred Alfred Beamish </Td> <Td> 3--6, 6--3, 1--6, 6--1, 7--5 </Td> </Tr> <Tr> <Td> 1913 </Td> <Td> AUS </Td> <Td> Parker, Ernie Ernie Parker </Td> <Td> NZL </Td> <Td> Parker, Harry Harry Parker </Td> <Td> 2--6, 6--1, 6--3, 6--2 </Td> </Tr> <Tr> <Td> 1914 </Td> <Td> AUS </Td> <Td> O'Hara Wood, Arthur Arthur O'Hara Wood </Td> <Td> AUS </Td> <Td> Patterson, Gerald Gerald Patterson </Td> <Td> 6--4, 6--3, 5--7, 6--1 </Td> </Tr> <Tr> <Td> 1915 </Td> <Td> BRI </Td> <Td> Lowe, Gordon Gordon Lowe </Td> <Td> AUS </Td> <Td> Rice, Horace Horace Rice </Td> <Td> 4--6, 6--1, 6--1, 6--4 </Td> </Tr> <Tr> <Td> 1916 </Td> <Td_colspan="5"> No competition (due to World War I) </Td> </Tr> <Tr> <Td> 1917 </Td> </Tr> <Tr> <Td> 1918 </Td> </Tr> <Tr> <Td> 1919 </Td> <Td> BRI </Td> <Td> Kingscote, Algernon Algernon Kingscote </Td> <Td> AUS </Td> <Td> Pockley, Eric Eric Pockley </Td> <Td> 6--4, 6--0, 6--3 </Td> </Tr> <Tr> <Td> 1920 </Td> <Td> AUS </Td> <Td> O'Hara Wood, Pat Pat O'Hara Wood </Td> <Td> AUS </Td> <Td> Thomas, Ronald Ronald Thomas </Td> <Td> 6--3, 4--6, 6--8, 6--1, 6--3 </Td> </Tr> <Tr> <Td> 1921 </Td> <Td> AUS </Td> <Td> Gemmell, Rhys Rhys Gemmell </Td> <Td> AUS </Td> <Td> Hedeman, Alf Alf Hedeman </Td> <Td> 7--5, 6--1, 6--4 </Td> </Tr> <Tr> <Td> 1922 </Td> <Td> AUS </Td> <Td> Anderson, James James Anderson </Td> <Td> AUS </Td> <Td> Patterson, Gerald Gerald Patterson </Td> <Td> 6--0, 3--6, 3--6, 6--3, 6--2 </Td> </Tr> <Tr> <Td> 1923 </Td> <Td> AUS </Td> <Td> O'Hara Wood, Pat Pat O'Hara Wood </Td> <Td> AUS </Td> <Td> St. John, Bert Bert St. John </Td> <Td> 6--1, 6--1, 6--3 </Td> </Tr> <Tr> <Td> 1924 </Td> <Td> AUS </Td> <Td> Anderson, James James Anderson </Td> <Td> AUS </Td> <Td> Schlesinger, Richard Richard Schlesinger </Td> <Td> 6--3, 6--4, 3--6, 5--7, 6--3 </Td> </Tr> <Tr> <Td> 1925 </Td> <Td> AUS </Td> <Td> Anderson, James James Anderson </Td> <Td> AUS </Td> <Td> Patterson, Gerald Gerald Patterson </Td> <Td> 11--9, 2--6, 6--2, 6--3 </Td> </Tr> <Tr> <Td> 1926 </Td> <Td> AUS </Td> <Td> Hawkes, John John Hawkes </Td> <Td> AUS </Td> <Td> Willard, James James Willard </Td> <Td> 6--1, 6--3, 6--1 </Td> </Tr> </Table>
