He contributed to other scientific journals, and made an immense number of contributions to the Australian press. In 1872 a equatorial refracting scope was purchased for the observatory, in 1881 Tebbutt discovered another great comet, now designated C/1881 K1, and in 1886 a new telescope of aperture and focal length was purchased, which enabled him to considerably extend his operations. He published in 1887 History and description of Mr. Tebbutt's observatory, Windsor, New South Wales, and followed this with a yearly Report for about 15 years. Between 1868 and 1902 he made 396 lunar occultation observations. A branch of the British Astronomical Association was established at Sydney in 1895 and Tebbutt was elected its first president. In 1904 in his seventieth year he discontinued systematic work, though he retained his interest in astronomy and continued to do some observing, and in the following year the Royal Astronomical Society of London recognised his work by awarding him the Jackson-Gwilt Medal of the society. In 1908, Tebbutt published his Astronomical Memoirs, giving an account of his 54 years' work, and he was much gratified in 1914, during the visit of the British association, by a visit to his observatory of a small party of astronomers. He died at Windsor on 29 November 1916. The year after his death his son delivered John Tebbutt's working library and manuscripts to the State Library of New South Wales. The John Tebbutt Memorial Collection is made up of 3,676 printed volumes, 117 volumes of manuscripts and 235 pamphlets. He was commemorated on the reverse side of the Australian one hundred-dollar note (in circulation 1984 until 1996 when it was replaced by a portrait of Sir John Monash).
