The argument addressed to me on behalf of the Commissioner was, in effect, that the road trains were used for the separate transportation activities of the lastmentioned company, that those activities formed no part of anyone's pastoral pursuits, and that therefore the case is outside s. 57AB. No doubt such an argument should succeed in a case where the transportation company is in a practical sense conducting an independent business of its own. But in the circumstances of the present case it seems to me that a comprehensive view ought to be taken of the total business enterprise that was being carried on in the Northern Territory by all the companies that were associated together in what Mr. Helsham called the management complex. It seems to me that until the road trains were acquired the process of droving the cattle from Helen Springs to the railhead at Mount Isa was simply the culminating stage of an activity which as a whole was a pastoral pursuit. The breeding, rearing and fattening of the cattle did not constitute the whole of that pursuit. The cattle had to be got in one way or another from station to station and ultimately to the railhead. The Commissioner's submission is, in effect, that when the stock left Helen Springs, at least in a case where their immediate destination was the meatworks and not another pastoral property, pastoral pursuits, so far as those cattle are concerned, were over. Indeed the submission goes a little further. It limits pastoral purposes to the raising, breeding and rearing of livestock, so that even the loading of them onto vehicles while still on a pastoral property, for the purpose of their being transported to market or to a railhead, could never form part of pastoral pursuits. This seems to me too narrow a view. If it is the pastoralist himself who moves the cattle, doing so as an integral part of the carrying on of his pastoral business, I see nothing in the normal sense of the expression "pastoral purposes" to exclude that movement from its ambit. Clearly, I should have thought, the droving of Helen Springs cattle to Mount Isa was properly to be described as done for the purposes of pastoral pursuits. If so, why is not the use of motor transport in place of droving equally to be so described? It was done by a different corporate entity, Northern Cattle Transport Co. Pty. Ltd., but still as part of the one process the component parts of which were each performed by whichever company in the group it was found convenient to use. I see no more reason in this case for treating the separate corporate existence of the associated companies as decisive than there was in Apthorpe v. Peter Schoenhofen Brewing Co. Ltd. [1] . The question in the case is essentially practical. I take it to be whether the use to which the road trains were put was a use in the course and for the furtherance of pastoral pursuits. If it had been for the purposes of pursuits disjoined from the breeding, rearing and fattening of cattle my answer would be, No. But where, as here, transportation by means of road trains to a railhead is an ancillary but integral part of a process being carried on as a whole of which the breeding, rearing and fattening of cattle are earlier stages, I think the answer should be, Yes. And I do not think that it makes any difference to this essentially practical question that separate corporations perform the several steps in that process, provided that their relation to one another is such that the process really is, in a business sense, carried on as a whole.
