Senator Chris Evans: The Prime Minister has provided the following answer to the honourable senator's question: I am advised that letters for the Prime Minister, the Office of the Prime Minister and the Chief of Staff to the Prime Minister are usually printed on plain paper with the 'letterhead' being part of the electronic document. For the Prime Minister, the department uses 'Stephen Swiss White' 115gsm A4 paper and matching DL envelopes. The cost of the Stephen Swiss White paper and envelopes are: one ream (500 sheets) is $32.87 or $26.40 per ream if bulk orders (50 reams or more) are placed, and DL envelopes are $76.50 per box of 500. For the Office of the Prime Minister (including Chief of Staff) standard white paper (A4 80gsm) and standard white envelopes are used. The cost of standard white paper and envelopes are: one ream (500 sheet) of standard white paper is $6.50, and the envelopes are ordered in batches of 5,000 and are $748.00 for 5,000. Occasionally additional letterhead may be purchased for the Prime Minister and her Office. This occurred in 2010 at a cost of $8,189 (GST exclusive). The total cost, however, of producing letterhead for the Prime Minister and her office in any given period cannot be identified as stationery used for electronic letterhead is ordered in bulk, sometimes for several portfolio ministers, and then used over an extended period. These costs have therefore been presented as an amount per ream or batch of stationary.
