There may have been other children who died in infancy. Joshua and Sarah and the three children above immigrated to Moreton Bay in 1853. Jeays purchased land and built 'Roma Villa' on the corner of Upper Roma and Skew Streets, Petrie Terrace, where he lived with his wife and family. His daughter Sarah Jane married in 1858 at Brisbane to Sir Charles Lilley, who went on to become Premier of Queensland. In 1862, Jeays paid £78 for 16 hectares of land along Simpsons Road, from the corner of Cooper's Camp Road, towards Ithaca Creek and abutting what is now Bowman Park, west of the area then known as Upper Paddington. His wife believed that living on this land would be healthier for her than their home on the 'Green Hills'. Accordingly, Jeays built a grand English-style home, using rough stone and decorated with gables and casement windows, naming it 'Bardon' after Bardon Hill in his native Leicestershire. The suburb was subsequently named 'Bardon' after this house, in 1926. However, by the time the house was completed his wife had died and Joshua was too broken-hearted to live in the house that he had built for his wife, and it was then occupied by his son Charles and later by Edwyn Lilley. The house was purchased by the Brisbane Diocese of the Catholic Church in 1925 and now stands in the grounds of St Joseph's Catholic Primary School, The Drive, Bardon. Joshua Jeays died on 11 March 1881 in Brisbane and is buried in Toowong Cemetery. with his wife Sarah who, as noted above, predeceased him, dying on 26 July 1864 in Brisbane. Sarah was originally buried in Paddington Cemetery but was most likely one of those re-interred in Toowong Cemetery.
Business life
Jeays started work in England as a carpenter. In Brisbane, he worked as a builder, architect and stonemason and was involved in the construction of the gallery of the original St John's pro-cathedral in the Queen's Gardens, as well as building homes of prominent Brisbane residents Walter Hill,, the infamous Patrick Mayne's 'Moorlands' at Auchenflower, and the Cribb family. He was also involved in the development of Brisbane's water supply and drainage system. Jeays built and provided the stone from his quarry at Woogaroo for Brisbane's first Government House, now part of the Queensland University of Technology's Gardens Point campus. He also partially built the George Street side of Parliament House, Brisbane, which John Petrie completed in 1868. Jeays built the Wharf Street Congregational Church, Brisbane.
Public service
Jeays was an alderman of the Brisbane Municipal Council, from 1859 to 1867, including serving as mayor in 1864. He also served on a number of committees, including:

Bridge Committee 1862 - 1864, 1866–1867
