It was not until 1825, or thereabouts, that free white settlers, many Irishmen among them, came in any substantial number to the Mother Colony of New South Wales, and not until 1832 that these men began to press claims for the management of their own affairs, under the inspiration of an Irish surgeon's son, William Wentworth, the Hampden of Australia. The later Colonies rapidly came into line, Western Australia, for the reason given above, remaining stationary. The first representative institutions were granted in 1842 to New South Wales, and in 1850 to Victoria, South Australia, and Tasmania. At that date, therefore, these settlements stood in much the same constitutional position as the Canadas had stood in 1791 (although technically their Constitutions were of a different kind), but with this important difference, that the Act of 1850, "for the better Government of Her Majesty's Australian Colonies," gave power to those Colonies to frame new Constitutions for themselves. This they soon proceeded to do, each constructing its own, but all keeping in view the same model, the British Constitution itself, and aiming at the same ideal, responsible Government by a Colonial Cabinet under a Government representing the Crown. Since responsible Government in Great Britain itself was not a matter of legal enactment, but the product of slowly evolved conventions and precedents, to which political scientists had not yet given a scientific form, it is no wonder that the colonial Constitution-makers found great difficulty in expressing exactly what they wanted in legal terms, and, indeed, none of them came near succeeding; but time, their own political instinct, a succession of sensible Governors, and the forbearance of the Home Government solved the problem, and evolved home-ruled States legally subordinate to the Crown, but with a Constitution closely resembling our own. The Constitutions became law by Acts of the Imperial Parliament passed by a Liberal Ministry in 1855. They are of unusual interest because they represent the first rude attempt to put into legal language a small part of the theory of the British Constitution as applied to dependencies of the Crown. In the most vital point of all, the relation of the dependency to the Home Government (as distinguished from questions of internal political structure), they are almost as reserved as the Canadian Act of 1840, which, as we have seen, did not recognize by a word the duty of the Governor to govern through a Colonial Cabinet. In certain clauses they hint, by distant implication, at the existence of such a Cabinet, responsible to the colonial popular Legislature--the Canadian Act did not assume even that--but they do not anywhere imply that the Governor is bound normally to place himself in the hands of that Cabinet, while they expressly and rightly reaffirm the supreme power of the Crown, whether acting through the Governor or not, over colonial legislation.
