Although the company confirmed the plans, Google didn't show up because Australia's authorities prohibited the search giant to fly at the 600 meters altitude for taking photographs.
Although it was quite an unpleasant situation for the well known Internet giant, it managed to capture several high resolution images with Sydney. All the photos were included in Google Maps today, offering some impressive panoramas for all the viewers. As you can see, the company tried to improve the quality of the images by taking photos from multiple angles and it really managed to draw some impressive 3D view for certain buildings.
Since the inclusion of the high resolution images in Google Maps, the company didn't made any official announcement but I guess all the photos are also available in the downloadable version of the maps, Google Earth.
