Two very useful NSW Government information sources on bicycle facilities are the RTA "NSW Bicycle Guidelines" Chapter 11 (.5Mb pdf) and the DIPNR "Planning Guidelines for Walking and Cycling" section 7.6 (2nd half of this 1Mb pdf). Both are packed with useful information and are highly recommended reading. The latter includes a chart with suggested bicycle parking provision rates for different land uses (residential, retail and commercial). For the full RTA NSW Bicycle Manual 8.9Mb pdf file, 92 pages.
If you're hungry for more technical detail, Austroads Guide to Traffic Engineering Practice Part 14 - Bicycles is the guide all Council and road authority traffic engineers use to design bicycle facilities. The tenth chapter is "End of Trip Facilities" and gives useful information about the provision of parking, showers and lockers. To get hold of Chapter 10 of Part 14, you can buy it from Austroads for $66. Or you can buy a discounted copy from BicycleNSW by calling 9281 4099. Or, you could go to the State Library and photocopy the chapter there, in the public interest.
