The Melbourne Harbor Trust Act 1928, by which the Melbourne Harbor Trust Commissioners are constituted, is expressed to be an Act to consolidate the law providing for the Regulation, Management and Improvement of the Port of Melbourne and certain portions of the River Yarra Yarra and certain portions of the Maribyrnong River and for other purposes connected therewith. By s. 46 the bed and soil and shores of the waters and the pieces or parcels of land within the metes and bounds described in certain parts of a schedule to the Act are thereby declared to have been vested in the commissioners under former Acts relating to the Melbourne Harbor Trust upon trust for the purposes of the said Acts and provision is made for the same lands to continue to be vested in the commissioners upon trust for the purposes of the Melbourne Harbor Trust Act. "The Port" is defined by the Act to mean so much of the Port of Melbourne the waters falling into it and the lands on the margin as is included within the metes and bounds referred to above with one immaterial exception. The Act makes comprehensive provision with respect to the powers of the commissioners and it is of some importance to refer to some of its provisions. Perhaps the leading provision is s. 48 which declares that, except as expressly provided in other sections of the Act, the exclusive management and control of the port, shipping, lightships, buoys, beacons, moorings, wharves, docks, piers, jetties, ferries, landing-stages, slips or platforms, lighthouses and the preservation and improvement of the port generally shall be vested in the commissioners and shall not be interfered with by any person whatsoever. Section 47 casts a duty upon the commissioners to maintain the piers vested in them by the Melbourne Harbor Trust Act 1912 Vict. and any extensions of such piers and of railway lines on such piers and extensions thereof and of machinery and appliances a???ixed to such piers in good order and condition and of such strength and stability as to carry safely any locomotives carriages and waggons of the Victorian Railway Commissioners. The commissioners may resume (s. 49) or sell or lease land (ss. 50 and 51); they may acquire, construct, equip, maintain and manage docks and dockyards within the port and carry on business as dockyard proprietors, shipwrights and ship repairers (s. 60), construct, erect and maintain such depots and sheds for the reception of goods and construct, erect and maintain such steam engines, cranes, hoists and weighing machines and other apparatus for facilitating the loading and discharging or the masting or unmasting of vessels and provide such other conveniences upon or near the wharves docks piers sheds landing-stages slips or platforms as the commissioners think expedient for the trade of the port (s. 62). For the purpose of maintaining and improving the navigation of the rivers within the port the commissioners may from time to time as occasion may require dredge, cleanse and scour the said rivers and alter vary deepen restrict cleanse scour cut enlarge diminish contract shorten widen straighten and improve the bed and channel of the said rivers (s. 64). By s. 91 a duty is imposed upon the commissioners to make and maintain proper roads and approaches to all wharves docks piers jetties landing-stages slips or platforms depots and sheds erected upon the lands vested in them or which might thereafter be erected and by s. 89 they are authorized, subject to the conditions therein specified, to raise destroy remove or take away any vessel or wreck of any vessel which has sunk or stranded within the port. By s. 138 wide regulation-making powers are conferred upon the commissioners. In particular, the commissioners are authorized, subject to the provisions contained in the Act and so far as consistent therewith, to make regulations for or relating to any of a number of subjects including: - (i) the improvement and management of the port; and (q) the working of coaches cabs drays carriages and other vehicles and the conduct and behaviour of porters carters draymen coachmen ferrymen and others resorting to the rivers piers wharves docks jetties landing-stages canals or other work within the port, and for prohibiting persons from acting as porters carters draymen and cabmen within the port without previously obtaining a licence to that effect, and generally for carrying out the objects and purposes of the Act.
