New South Wales volumes include the licence class of high-security allocation remaining for:

bulk (i.e. within irrigation trust) and individual irrigation
environment
where the purpose is generally not known.

The value for Murrumbidgee – NSW includes 15 ML corresponding to new licences issued during the year.

No information specific to this entitlement class available for Victoria. See Line item 25.1.9.7 Allocation announcement on regulated flows – other lumped holders

In Queensland, the resource operation plans (ROPs) distinguish between ‘high and medium priority of supplemented water allocation’ (names used in Queensland, corresponding to high and general/low-security classes of water access entitlements (WAEs), respectively, in the National Water Account 2010). In most cases, what the ROPs classify as high priority actually correspond to urban purpose. The water audit monitoring (WAM) data, however, only distinguish between ‘supplemented’ and ‘unsupplemented’ entitlements, distinguishing for ‘supplemented’ only, urban purpose from all other purposes. For this reason, the 2010 Account reports all ‘supplemented’ entitlements in Queensland under ‘other lumped WAE’ class. The 2010 Account further splits Queensland ‘supplemented’ entitlements between urban purpose, reported under ‘urban holder’ (Line item 25.1.9.4), and all other purposes, reported under ‘individual irrigator holder’ (Line item 25.1.9.2) and ‘other lumped holders’ (Line item 25.1.9.7).

No other state has high or general/low-security classes of entitlements.

Data provider

MDBA.

Method

Allocation announcements are usually the entitlements on issue multiplied by the percentage allocation announced.
Allocation announcement is calculated by the states and provided to the MDBA.

Uncertainty

The uncertainty value for the New South Wales data provided in this line item is +/–10%.

Approximations, assumptions, caveats/limitations

The line item contains only New South Wales data.
Victorian and Queensland WAM data received by MDBA did not allow separation into high and general/low-security classes.
