Some historians claim that the similarities are largely coincidental, that there is only circumstantial evidence for a relationship between the two codes, and any resemblances are the result of something akin to parallel or convergent evolution.
More recent evidence primarily from Irish and English researchers including Tony Collins, Joe Lennon, Geoffrey Blainey and Aaron Dunne point to the GAA creating Gaelic Football as a hybrid of existing football codes (codifier Maurice Davin in an effort to differentiate from rugby has been found to have been making extensive notes on Association Football (soccer) from which some of the rules were based),[9] and the Victorian Rules of 1866 and 1877 (which the modern Australian rules is based on), which were popular and widely distributed.
Since the 1980s, some Gaelic players, such as Jim Stynes and Tadhg Kennelly, have been recruited by the professional Australian Football League (AFL) clubs and have had lengthy careers with them.
levels of competition, providing a strong financial lure for Irish players to switch to Australian football.
The earliest record of a recognised precursor to the modern game date from a match in County Meath in 1670, in which catching and kicking the ball was permitted.
[10] The earliest recorded inter-county match in Ireland was one between Louth and Meath, at Slane, in 1712, about which the poet James Dall McCuairt wrote a poem of 88 verses beginning "Ba haigeanta".
GAA founder and Irish nationalist Michael Cusack wanted the rules of Gaelic football to differ from rugby union, which was making headway in Ireland at the time.
B. Thompson, fellow students at Cambridge's Trinity College; and Irish Australian Thomas H. Smith, who played rugby football at Dublin University.
[11] Historians such as Geoffrey Blainey have argued that the origins of Australian rules football lie purely with rugby and other English public school games.
In 1843, Irish immigrants in South Australia celebrated St Patrick's day by playing a game of caid in Thebarton.
For example, Patrick O'Farrell has pointed out that the Irish sport of hurling, which has similar rules to Gaelic football, was played in Australia as early as the 1840s, and may also have been an influence on the Australian game.
Their presence in Victorian football may be accounted for in terms of a formative influence being exerted by men familiar with and no doubt playing the Irish game.
[15] British historian Tony Collins argues strongly that the GAA hybridised Australian rules and soccer to differentiate from rugby, however takes the view that the development of Australian rules in the late 19th century was likely influenced by traditional Irish hurling (rather than Irish football) and points out that this sharing of codes across sports is a natural byproduct of globalisation.
[16] Bill Mandle notes that although it lacks evidence that Gaelic Football's come into being in 1880s is a possible indication of Irish Australian influence back home.
Jack Worral in 1926 wrote that the "Father of Australian Football" H. C. A. Harrison who had sought to "code of our own" in 1859 was genuinely surprised in 1927 to learn that the Irish had been playing a very similar game since the 1880s.
The present evidence, however, suggests that Gaelic football made its own way … which happened to be—in the style rather than the formalities of play—in the Australian direction.Irish historian Garnham, citing R.M.
Peter's Irish Football Annual of 1880, argued that Gaelic Football did not actually exist before the 1880s and curious on the origin of the distinctive features was of the belief that clubs from England in 1868 were most likely introduced elements of their codes including the "mark" (a decade after it had been introduced in Australia) and scoring by kicking between the upright posts.
Like the Victorians, the GAA worked hard to create a game that would differentiate from the popular British sports of rugby and soccer.
One theory suggests that the origin was Archbishop Thomas Croke, one of the founders of the GAA, was the Bishop of Auckland and lived in New Zealand between 1870 and 1875.
[24] Croke had ample opportunity not only to witness the Australian game being played but obtain copies of the rules which were widely published and distributed.
[25] Like Davin, GAA founder Michael Cusack had both a brother and a sister John and Mary who had emigrated to Australia at a similar time.
Australian rules is capable of producing a diverse range of kicking styles, the drop punt is most commonly used in the modern game, more so at professional levels.
The instep is the most popular style based on culture, the drop punt used in Gaelic is a far superior kick in terms of distance and accuracy, but is rarely taught.
[30] Australian rules has evolved to have sleeveless jumpers, whereas Gaelic footballers wear short sleeved outfits similar to soccer or rugby tops.
