Newbery also excelled in boxing, swimming, motor racing, fencing and rowing, among other sports.
In 1895 he took part in a historic fight to determine the superiority of boxing (defended by Newbery) or savate (defended by Carlos Delcasse), which established boxing as a popular sport in Argentina.
He won important boxing titles in 1899, 1902 and 1903.
On 8 July 1903 he decisively beat professional boxer Clark.

In October 1901 he won first prize for fencing with foils in the South American tournament organised by the Gymnastics and Fencing Club.
In 1905 and 1906 he won the foil fencing contests organised by the Buenos Aires Jockey Club, where he also defeated the French swordfighting champion Berger.

On 16 March 1908, representing the Buenos Aires Rowing Club, he won the 1000 m race against the champion Müller brothers.
In 1910 he joined the team which established the speed record for a boat with four long oars.

In 1902 he won the first prize in long-distance diving in the Luján river, covering 100 m. He was one of the personalities who most encouraged the practice of the sport in Argentina, although he is not well-remembered for this.

In 1980 the Konex Foundation posthumously granted him the Konex Award for his supporting role in Argentine sporting history.

He also played football for National Foot–Ball Club, and in 1934 they changed their name to his.
