ICAC reported that after the contract for purchase of the Currawong property was executed and exchanged on 15 March 2011. However, given the caretake period of government when such actions are not to be undertaken, questions were soon raised within the government about whether the purchase was authorized. On 17 March 2011 the Director General of the Department of Premier and Cabinet NSW engaged the Internal Audit Bureau (IAB) to investigate Watkins' authority to purchase the site. The following day, the Director General stood Watkins down and met with Watkins where he was told that that he had not been authorized to purchase the land. Subsequently Watkins contacted Kelly and asked if he would sign a letter - backdating it - confirming their alleged understanding that Watkins was authorized to purchase the Currawong property. The effect of the backdating of the letter was to convey that authority was given on 28 February 201, prior to the exchange of contracts. Thus, the provision of the backdated letter to the IAB investigator finding that Watkins was authorized to execute the contracts for the purchase of the site by Kelly.
