Note Printing Australia (NPA) is a wholly owned subsidiary of the Reserve Bank of Australia (RBA) that produces banknotes and passports. It was corporatised in July 1998 and is located in Craigieburn, Melbourne. NPA has its origins as a subsidiary of the Commonwealth Bank and was established in 1913 to print banknotes for Australia. After printing paper banknotes for 75 years, NPA introduced the first polymer banknote technology in 1988. NPA print banknotes for several other countries as well as Australia due to the high standards of durability and difficulty of counterfeiting.
