'Implementation of the Intergovernmental Agreement has already delivered significant economic benefits as a result of a first phase of taxation reforms from as early as 1 July 2000. As part of the initial reforms:
the Australian Government fully implemented its commitments by:
removing the wholesale sales tax;
implementing the GST; and
ensuring that all GST revenue is provided to the States and Territories; and
the States and Territories partly implemented their commitments by abolishing a first tranche of state taxes by 1 July 2005:
accommodation tax;
financial institution duty;
quoted marketable securities duty; and
debits tax.'
'Even though GST revenues are now sufficient so that the States and Territories would not be worse off, relative to if the previous financial arrangements had continued, they have so far refused to fulfil their commitments by nominating a timetable for abolishing this final remaining tax (edit: mine Stamp Duty).'
