The Null Device
The South African capital, currently known as Pretoria, is being renamed to Tshwane, the name of an ancient African king, and also a word meaning something like "unity". The renaming has to do with breaking links with the old colonial white minority regime.
By the same token, perhaps when the republican debate restarts in Australia, we can expect proposals for renaming Australian cities. After all, why should cities bear the names of dead English noblemen like Viscount Sydney or Lord Melbourne (let alone areas named after imperial war heroes like Baron Collingwood)? Perhaps, if Germaine Greer's Aboriginal republic ever comes about, Sydney can be renamed to "Warrane" or similar, and other places can have similar post-colonial name changes.
