Along with the usual Windows Phone features, the 900 includes the Nokia Music service, Nokia Transport (directions to public transport), Nokia City Lens (augmented reality), and a collection of local apps from businesses such as Qantas, Australia Post and Foxtel.
The 900 goes on sale next month at $699 from major retailers. It will also be available from Optus for $0 upfront on a $60 plan. Not all outlets will offer the full range of colours.
The Lumia 610 is aimed at those on a tighter budget. With a recommended price of $329, it will be available from Boost Mobile in June and from Vodafone and major retailers in July. It comes in the same colour range as the 910, and with the same proviso regarding availability.
Built around a single core 800MHz CPU and a 3.7in screen, features include HSDPA (7.2Mbps) connectivity and a 5MP camera. The software bundle includes maps, turn-by-turn navigation, Nokia Transport, and Nokia Music.
