Establishing the Contract

​A contract defines the rights and obligations of both parties once the contract is awarded and is established when an offer is made and accepted.

Depending on the complexity, value and type of goods, services or works being contracted, government agencies will enter into a contract by:

  • paying for the goods, services or works provided;
  • issuing a letter of acceptance;
  • issuing a Purchase Order; or
  • using a more formal written Agreement / Contract which is signed by both parties.

Regardless of the approach, a contract is formed between the Government and the supplier in each case.

For complex or high value purchases, it may be necessary for the parties to enter into negotiations prior to finalising the contract. The purpose of these negotiations is to:

  • test your understanding and assumptions in determining your costs;
  • clarify and rectify any false assumptions;
  • achieve operational refinements and enhancements that may result in cost reductions.

If negotiations are allowed, you will generally be advised that this will be the case in the procurement documentation. The outcomes of these negotiations are reflected in the final contract. Once completed and agreed a contract is then established.

The Government's Confidentiality Policy applies to all contracts entered into by Government agencies. The policy provides that in any contract between the Crown and another party, confidentiality requirements in relation to the provisions of the contract are not to be included unless an exemption has been approved. Exemptions are available in specified circumstances. ​
