Many years ago it was widely claimed in the electronics industry, including by Philips when they manufactured radiocommunications equipment in Australia, that manufacturers and importers had to supply spare parts for 7 years after a particular product was no longer sold.
Prior to the Trade Practices Act, there were also claims that importers had to hold a certain value of spare parts for the electronics products that they sold in Australia but I cannot comment on the veracity of this claim.
