This article is FULL of it. It's fairly long too, so this is fair usage:
However, data collected by the Australian Bureau of Statistics shows that Lebanese make up the fifth largest ethnic group in Australian prisons after Australians, New Zealanders, Vietnamese and British and Irish, with 226 Lebanese prisoners last year accounting for 0.75 per cent of all detainees held for serious crimes.
Per head of population, Lebanese-born people had the seventh highest rate of imprisonment (after Samoans, Tongans, Sudanese, Vietnamese, Romanians and Indonesians).
Victoria's then police commissioner Christine Nixon denied there was a problem, although Vicpol's statistics suggested young Sudanese were being arrested at roughly four times the average rate. The ABS report Prisoners in Australia shows that last year Sudanese had the third highest imprisonment rate (after Samoans and Tongans) of any nationality.
Similar concerns were voiced in South Australia in 2008, when deputy police commissioner Gary Burns said his force faced "an emerging, probably contemporary, policing issue", with 450 offences having been committed by 93 members of a Sudanese community numbering 1500 in the space of 16 months.
