Hmmm well although Lajamanu is rather far from other places it is very well connected with Yuendamu which is probably the largest community in the area where Walpiri (Walbiri) is spoken and also close (in Tanami desert terms) to Kalkaringi and Daguragu and Willowra where Walpiri also spoken. This community is actually on Gurindji tribals lands so already people the language is 'foreign' for the location and speakers of English, Walpiri, Gurindji, Gurindji Kriol, Mudjaba (?spelling?) and Pitjantanjaric languages live in the area with many people speaking multiple languages. With the mixing of groups like this a creole highly likely to develop and in fact you see this very clearly to the North and East of there where 'Kriol' is recognised, that this is a new language somewhat surprising and perhaps some of our resident language specialists would like to comment on the definition being used here not a creole or a dialect but called Walbiri 'Lite'
. That this is among only young people whose parents probably speak different native languages and have heavy exposure via media and school etc to the dominant outsider language (English) this is rather a strong motivator for language change
