An internal Department of Immigration and Border Protection document, seen by Crikey, reveals that the Australian government knew that the Nauruan government was planning to "open" the asylum seeker detention centres on the island before the legislation was even put before Nauruan parliament. Not only that, but the Australian government planned to use the "opening" of the centres as an argument in a case before the High Court -- all before the allegedly independent decision by the Nauruan government was made public.
