Singh was described as tall and wiry, a commanding figure, deeply-bronzed and very clear skin, white teeth, trimmed moustache, penetrating dark eyes, does not bore with anecdotes, and 'had beaten all the great wrestlers [of the world] except the giant, George Hackenschmidt, and was even prepared to back his comparatively diminutive frame against the colossal strength of Sandow'.

[12] On Saturday 9 June 1900 at the Victoria Hall in Melbourne, the best-of-three contest took part between Singh 'of India' and William Pagel (1878–1948) of Germany, stated to be a revival in wrestling.

[13] It was reported Singh, lithe and sinewy, weighing 12 stone 7 pounds (79 kg; 175 lb), had 'held the belt' against all-comers for many years, winning 82 of 85 matches.

The catch-as-catch-can or Lancashire wrestling rules included for the match were:[13] Many spectators in red turbans and Singh's attendant Jack Graham saw him take the first fall at 23 minutes and 30 seconds.

Monday 15 April 1901 saw a wrestling match between Jim McDermott, from Newcastle, New South Wales, and Singh, at Melbourne's Democratic Club, for the 'championship of Australia'.

[15] After delays starting due to selecting a judge acceptable to both parties, the first bout saw McDermott go for a neck hold but soon Singh took him to the mat and put on a strong underhold.

[17] Wirth's Circus in Melbourne was to see a closely contested wrestling match between Singh and Brahm on Thursday 30 April 1903, with a substantial wager for the championship of Australia.

[21] In May 1904 (also reported as October 1904, and 6 November 1904),[11] with the Wirth Brothers Circus, offering £10 for any person he could not pin in 15 minutes, 42-year-old Singh wrestled the 24-year-old Clarence Weber (1882–1930).

Whilst years before Tom Cannon had taken the championship from Jack Connor using a strangle hold without issue, and it was not debarred from the competition, it was not accepted this time from the crowds.

[8] With the 3 stone (42 lb; 19 kg) heavier Weber prostrate across the ground intending to wait out the time unpinned, Singh used the unpopular but legitimate strangle; but it nearly resulted in a riot.

[1][23] While Brahm had strutted out in a long red velvet coat trimmed with gold cord, Singh stepped onto the mat without 'no gorgeous rainment covering the lithe Sihk.

On Friday 12 June 1908 at the Melbourne Athletic Club, Exhibition Street, in the catch-as-catch-can wrestling style, Singh competed with George Dinnie (1875–1939).

[32] By October Gunga Brahm was advertising in the newspapers to get invited to the series of matches between Singh, George Dinnie, and Peter Bannon.

[10] With double-barred Nelsons and strangle-holds prohibited, after four continuous and punishing hours without a fall, Irslinger gave in, and Singh was declared 'champion of the world'.

Whilst not comparing the day's current wrestlers to their predecessors, he did not care for the Boston crab, toeholds, and other grips, indicating it spoiled a clean sport.

[8] Singh allegedly by July 1906 'had taken unto himself a wife and a pub, so his time was fully occupied in attending to the beer and telling Desdemona of the battles he had waged on the mat'.

Advertised as the 'Hindoo Wonder Worker', Singh appeared as the 'exceptional vaudeville attraction' at the Carlton Theatre, Kogarah, southern Sydney, for Saturday 27 August 1927.
