To meet the case when the value of wheat f.o.r. Australian ports rose above 5s. 2d. per bushel, provision was made by the Wheat Tax Act 1938 for a tax upon wheat grown in Australia, and, on and after a date to be fixed by proclamation, sold to a wheat merchant; and by the Flour Tax (Imports and Exports) Act 1938, s. 4 (b) for a tax upon all wheat exported from Australia, on or after a date to be fixed by proclamation, not being wheat upon which tax was imposed by the Wheat Tax Act 1938. The formula for these taxes was as follows: - "The rate of tax, not in any case exceeding one shilling per bushel of wheat shall be at such rate per bushel of wheat as the Minister, from time to time, and in accordance with a recommendation by the Committee, declares, by notice published in the Gazette, to be the amount which bears the same proportion to the excess of the price of a bushel of wheat free on rails at Williamstown in the State of Victoria, at the time of the recommendation by the Committee over five shillings and twopence as the quantity of wheat which, in the opinion of the Committee, will be consumed in Australia (whether as wheat or as products derived from wheat) during the twelve months following the preceding first day of October bears to the total crop which, in the opinion of the Committee, will be harvested during that period." The Act relating to the imposition assessment and collection of all these taxes was the Flour Tax (Wheat Industry Assistance) Assessment Act 1938. Section 12 (2) of this Act provided that the tax upon wheat exported from Australia on and after a date to be fixed by proclamation should be paid by the exporter of the wheat. Section 13 (2) provided that the tax imposed by the Wheat Tax Act 1938 should be paid by the wheat merchant to whom the wheat was sold. The Wheat Industry Assistance Act 1938 provided for the destination of the proceeds of these taxes. Section 5 provided for the opening of a fund to be known as the Wheat Industry Stabilization Fund, into which there should be paid all moneys from time to time collected under the Flour Tax (Wheat Industry Assistance) Assessment Act 1938. Section 6 (1) provided that, subject to this Act, the moneys standing to the credit of the fund should be applied in making payments to the States as grants of financial assistance. Section 6 (3) provided that there should be kept in the fund an account to be known as the Wheat Industry Special Account to which there should be credited out of the receipts of the fund in the first year the sum of £500,000, and in the following four years such amounts not exceeding this sum as the Minister determined. Section 6 (4) provided that there should be kept in the fund an account to be known as the Wheat Tax Account, to which should be credited out of the receipts of the fund all moneys collected under the Flour Tax (Wheat Industry Assistance) Assessment Act 1938 as a tax upon wheat exported from Australia or upon wheat produced and sold in Australia. Section 7 provided for the allocation from the Wheat Industry Special Account between the States of New South Wales, Victoria, South Australia and Western Australia. The amounts paid in the first year were to be applied in the provision of relief to distressed wheat growers and in the subsequent years towards meeting the cost of transferring wheat farmers from land unsuitable for the economic production of wheat, or to arranging for such land to be used for other purposes. Section 8 provided for payments from the Wheat Tax Account to the States by way of financial assistance upon condition that these amounts were distributed to the flour millers in these States in accordance with such methods of distribution as was decided by the Minister after advice from the State Minister. Section 10 provided that where the Governor-General was satisfied, inter alia, that (b) a State had not taken steps adequately to protect consumers of flour and other wheat products against excessive prices in respect of those commodities, the Governor-General might, by notice in the Gazette , suspend payments to that State under the Act during such periods as, in his opinion, (d) those consumers were not protected against such excessive prices. At the same time as this Commonwealth legislation, the States passed legislation for the purpose of fixing the minimum and maximum prices of flour and the prices of bread. This legislation took the form of authorizing the Governors of the States to make proclamations for this purpose. Pursuant to this authority a number of proclamations were made in the various States.
