The absence of any element of choice as to payment of the State levy weakens any link between the payment of the levy and the freeing of contributors from the obligation to make the relevant payments in that, if an organization had a choice as to whether to pay the levy, it would be apparent that a registered organization which elected to pay it did so to provide benefits, in the form of free out-patient (and ambulance) services, for its contributors. The connection between the levy and the provision of the free services is, however, clear enough under both the New South Wales and Victorian Acts. Thus, the provision in each State Act that no fee is to be payable in respect of the relevant services is expressly limited to services provided to a person who was, at the time the service was provided, a contributor to a fund conducted by an organization which is bound to pay the levy. The amount of the levy which an organization is required to pay is, under each State Act, determined by a formula which, subject to a discounting in the case of dependants, will reflect the number of persons who will be entitled to receive free services by reason of contribution to a fund conducted by that organization. The inferences are plain that the entitlement of contributors to a fund conducted by a hospital benefits organization to receive free out-patient (and ambulance) services is a benefit which is related to the obligation imposed upon the relevant organization to pay the levy and that, as a matter of substance, that entitlement must be seen as, at least to some extent, provided at the indirect cost of that organization. In the case of the Victorian Act, the making of those inferences is assisted by the express requirement (s. 9(2)) that an amount equivalent to the amount received by way of levy under the Act shall be paid into the Hospital and Charities Fund being the fund established under the Hospitals and Charities Act 1958 Vict.. In the case of both State Acts, the calculation of the levy which a particular organization must pay by reference to a formula which reflects the number of contributors under that organization's basic table accords with the underlying position that, in the case of a registered organization, all contributors to a hospital benefits fund must contribute under the organization's basic table and will derive, as contributors under that basic table and regardless of whether they also contribute for benefits under a supplementary table, all the benefits which the Act confers.
