(1) Within 7 days of receiving a notice under section 23, Australia Post must give written notice to the ACCC stating:
(a) whether Australia Post is supplying or has made an offer to supply a bulk interconnection service to the complainant on terms and conditions that are more advantageous to the complainant than the standard terms and conditions of the service; and
(b) if such a supply is being provided or such an offer has been made--details of the supply or the offer, as the case requires, including:
(i) the method by which any rate reduction in respect of the supply of the service is calculated; and
(ii) the method by which any period for which the rate reduction applies is calculated; and
(c) if no such supply is being provided and no such offer has been made--the reasons why the standard terms and conditions of the bulk interconnection service are appropriate.
(2) For the purposes of subparagraph (1)(b)(i), the method must show the component that is Australia Post's estimate of the average transport costs per letter avoided in relation to letters lodged with Australia Post for delivery in accordance with the terms and conditions of the bulk interconnection service which is or would be supplied to the complainant.
