From that shrunken link's PDF “Every Assistance and Protection”, from part of one paragraph on page 34 (of 256)
" Britain’s abolition of the passport for travel within the empire in 1826, and the conditions placed on applicants wishing to travel to foreign countries, resulted in the infrequent issuance of British passports the mid to late 19th century. The conditions were that British passports were issued ‘only to individuals known personally to the Secretary for Foreign Affairs, senior members of government, or travellers in the colonies known to the consular staff’, or when identity could be certified by personal knowledge of a member of the upper classes. Salter notes that these stipulations are a reflection of the class system in Britain.50 But it must also be noted that, during this period, the majority leaving Britain were assisted or free immigrants departing for a new life in the settler colonies of the empire, for which there was no requirement to hold a passport. As a consequence, there are few surviving examples held in Australian archives.51 "

51 is footnote for : Radhika Viyas Mongia, ‘Race, Nationality, Mobility: A History of the Passport’, Public Culture, 1999, vol. 11, pt. 3, p. 533, observes that the ‘extensive annual Emigration Proceedings, published by the Emigration Branch of the Government of (British) India from 1871, contain no index entries for the term ‘passport’ for thirty-five years’.
Australian State and National archives and libraries are similarly placed.
