[4] Hewitt was said to be a "champion climber", once climbing a tall gum tree on the banks of the Hindmarsh River in Victor Harbor and carving his initials in it at the top of the trunk with a tomahawk.

[8] Alongside Hewitt other noted Indigenous Australian sportsmen from Point McLeay were Mansell and Ephraim Tripp.

[13] On 29 May 1885 a football match on Adelaide Oval was organised by the SAFA between an All-Indigenous team (titled 'Aboriginals') captained by Hewitt and a combined team (titled 'Wanderers') selected by retired Port Adelaide player Thomas Smith composed of players from Port Juniors, LeFevre Peninsula, Fitzroy and Kingston.

[14] The 'Wanderers' side benefited by the inclusion of James "Joker" Hall and Harold Haldane of South Adelaide and George McKee and Edward "Ted" Woods of Norwood.

[15] The match was very close and ended in a draw with most who attended the game holding the view that Hewitt's side had the better of the play.

[18] On 2 June 1885, after the success of the 'Wanderers v Aboriginals' game, another match involving Hewitt and other Indigenous players was organised and played on Adelaide Oval.

[24] The Port Adelaide News, a local newspaper at the time, wrote a glowing appraisal of his play stating "The Medindies had their full strength; Hewit, an aboriginal, was a decided acquisition, and although he played barefooted was about the best man amongst them, his alacrity all through the game eliciting the applause of the spectators.

[16] On 29 June 1889 Hewitt had retained his place in the Medindie side and was joined by another Indigenous Australian, Alfie Spender, in a match against Norwood on Kensington Oval.

[30] Port Adelaide's captain Ken McKenzie positioned Hewitt in the team's full-back line at the start of the match.

[32] During the game the Port Adelaide supporters voiced their criticism regarding a holding the ball call made against Hewitt by umpire Schaeffer.

[40] Hewitt's Southern side would win the match with the South Australian Chronicle praising the play of himself and fellow Point McLeay teammate Wilson stating that "A feature of the game was the introduction of four natives from the Point Mcleay station, and as far as two of them — J. Wilson and Harry Hewitt are concerned they played the game of the forty in the first half, and subsequently did splendid service for their side.

On 15 April 1882 the North Adelaide Cricket Club travelled to Milang to play a team of locals supplemented by some residents of Point McLeay including Hewitt.

[46] In a match report for this game noted that "Wilson and Hewett (natives) at wicket and point respectively particularly distinguished themselves.

"[46]On 9 November 1885 the Milang Cricket Club travelled via a paddle steamer called the 'Bourke' to Point McLeay to play a game against the missions Indigenous population.

[47] On 21 November 1887 a cricket match between the 'Wanderers v. Aboriginals' was played on Adelaide Oval with the latter team made up of players from Point McLeay including Hewitt.

[49] It was reported that the Point McLeay residents whilst visiting Adelaide stayed on the Jubilee Exhibition Building grounds and were not allowed to leave the area without permission and were not to do so alone.

[52] In a match report of the Littlehampton game it was said that "the bowlers did not have much trouble with the other natives, but Hewitt's long stand quite demoralised the team".

[57] In 1895 whilst playing for a Northern Adelaide cricket team known as the Federal eleven against a side representing Prospect, Hewitt scored 144 not out.

Harry with his pants rolled knee high, no boots, standing right in line with the wicket, stern end almost to bowler, head low down, looking over left shoulder, and those flashing black eyes, made the more conspicuous by the large whites showing, was a most formidable object to bowl at.

[71] Hewitt wrote to, and was published by, the Adelaide Advertiser regarding his grievances about the treatment of Indigenous people in regards to fishing licences.

First, the white man took the land from us and killed our game, and now he expects us to pay £1 license before we can catch fish for the market.

[78] On 10 February 1905 Hewitt personally organised a corroboree with 20 other Indigenous Australians in Victor Harbour and it was said "almost the whole town turned out to witness the event".

[81] During Easter in 1906 the Our Boys Institute, a branch of the YMCA, visited Victor Harbour and Hewitt provided boomerang demonstrations for the organisations children.

[84] He would do the same fortnightly at the Point Macleay Mission urging locals to the claims of temperance and would organise men to play football games in Adelaide who were members of the Blue Ribbon Army.

[90][6] It was suggested in 1959 that the local geographic landmark in Goolwa colloqualily referred to as "Aggie's Knob" was named after Agnes.

[71] It was said that "Hewitt was a keen reader, and displayed wide knowledge of Australian and overseas events as outlined in his daily newspaper.

[96] The boat cost the Point McLeay Mission £120 in 1886 and was named after the first female Indigenous Australian in South Australia claimed to embrace Christianity.

[58] The only witness, Jennie Tripp, said that a quantity of wine had been consumed the previous evening before Hewitt and his friend Tommy Lawson began fighting.

[99] At the trial, which was for manslaughter, the jury accepted the argument that the stick produced could not have caused the fatal injury, and if he had struck the much stronger Hewitt, it was in self-defence, so returned a verdict of "not guilty".

[102] On 13 November 1930 a letter in the Observer by D.H. Griffin, the Mayor of Victor Harbour, emphatically held that Hewitt was not under the influence of alcohol at the time of his death.
