Queensland Legislative Council (a lifetime appointment). By the late 1880s he had built a summer house in Southport. With his brother, F. T. Gregory, he published their Journals of Australian Exploration in 1884. He was interested in scientific research and was a trustee of the Queensland Museum. Early in 1895, Gregory was appointed Grand Superintendent of Royal Arch Masonry in Queensland. On 25 June 1895 he opened the District Grand Chapter. On 6 November 1903, Gregory was knighted, being appointed Knight Commander of the Order of St Michael and St George (Imperial) in recognition of his service as Surveyor-General and in the Queensland Legislative Council. Gregory died on 25 June 1905 at his residence Rainworth at Rosalie, Brisbane. His body lay in state at the Masonic Hall in Alice Street where many people came to pay their respects; it was estimated that 1,400 people visited on the morning of the funeral. His funeral took place at the hall in the afternoon of 29 June 1905, after which a funeral procession of several hundred people walked along Alice Street, William Street, North Quay and the River Road (now Coronation Drive) to the Toowong Cemetery where hundreds of people were already assembled at the cemetery. Gregory was buried high on the northern slope of the hill below Governor Samuel Blackall's grave with Anglican rites conducted by his friend Rev. Thomas Jones of Indooroopilly. After his death, his home Rainworth was rented to a number of people, including Robert Philp. His farm land was eventually subdivided and, to facilitate this, the house Rainworth was relocated to another site, now 7 Barton Street in the suburb of Bardon. The house was added to the Queensland Heritage Register on 21 October 1992. In late 1905 Brisbane artist Oscar Fristrom sculpted a bust of Gregory. In February 1906, Fristrom offered to sell the bust to the Royal Geographical Society of Queensland but the society decided not to buy it; however, they did display it at an event in June 1906. For many years the bust was displayed at Freemasons’ Gregory Lodge in Cairns (Gregory being depicted wearing his Masonic regalia). In 2018, the Freemasons donated the bust to the Museum of Lands, Mapping and Surveying in Brisbane. As at 10 March 2020, the bust is at the entrance of the museum. Recognition and legacy Gregory has been honoured through the naming of many places in Australia,
