HP has been caught up in a political statement being made by a Sydney council.
The Greens-dominated Marrickville Council, in Sydney's inner west, is boycotting Israeli products after signing up to the Global Boycott, Divestment and Sanctions (BDS) movement in december.
Despite assurances from the Council's mayor that the sanctions won't financially disadvantage taxpayers a recently released Council business paper claims the plans could end up costing the public purse $4 million.
Of that, $3 million alone would be spent replacing all of the authority's HP computer systems.
Further money would have to be spent replacing other council hardware and cancelling contracts, if the full range of recommendations within the report were to be implemented.
The council is due to vote on the extent of the boycott on Monday.
The BDS movement was started in 2005 in protest over alleged oppression of Palestinians.
The BDS website claims that HP technology is used at Israeli military checkpoints that restrict the movement of Palestinians.
