In this thesis I describe aspects of referring expressions and referential practice in an English-lexified creole language spoken in the Ngukurr Aboriginal community, in the Northern Territory of Australia. Kriol has substrate influences from seven traditional Aboriginal languages. Dialects of Kriol are spoken in Aboriginal communities across the Top End of Australia; with estimates suggesting more than 20,000 people speak it as a first language. The language has a low status and in many contexts, such as health, medical and legal contexts, it frequently goes unrecognised as a legitimate language requiring interpreters. There is no comprehensive grammar of Kriol and as yet, there have been few in-depth studies into its structure and use. I investigate referential expressions in Kriol from various perspectives, using tools from a range of theoretical frameworks and research traditions, including descriptive linguistics, discourse analysis, information structure, and ethnopragmatics. The thesis provides an integrated description of how referential expressions are structured and how they are used in spontaneous talk to meet communicative needs. A further goal of this thesis is to demonstrate that there is significant continuity of referring strategies from Kriol's Aboriginal substrate languages. The data used in this study consists of a corpus of spontaneous discourse between two or more speakers, elicited material, and consultation with Elders on cultural issues relevant to language use. ... Each chapter contributes original description of the Kriol language. By combining a number of theoretical perspectives, the thesis offers an integrated description of the structure and function of referring expressions.

This thesis is a study of Bunuba, a language spoken around the township of Fitzroy Crossing in the West Kimberley region of Western Australia. Chapter 1 introduces Bunuba by discussing the location and sociolinguistic information and providing the reader with background to the language and its speakers. In this Chapter details of different speech registers and dialects are introduced and a brief review is undertaken of the previous research which has been carried out on the language and its speakers. Also included is a discussion of some contemporary uses of Bunuba and a description of my fieldwork methodology. This Chapter also sets this work apart from previous research on Bunuba, particularly that undertaken by Alan Rumsey. The differences between his work and the work presented in this thesis are outlined in Chapter 1. Chapter 2 describes the structure of the language detailing phonology and morphophonological procedures, word classes and nominal morphology. Chapter 3 discusses the formal structure of Bunuba verbal morphology.
