Water used on Australian farms

10.5 million megalitres of water were used by Australian farming businesses in 2017-18.

2.3 million hectares of agricultural land was irrigated (up 2%)
9.7 million megalitres (ML) of water was used to irrigate crops and pastures (up 7%)
22 thousand farms applied water to their land (up 2%)

Water used to irrigate crops and pastures

Pastures and crops accounted for most of the water used on Australian farms in 2017-18. Irrigated cotton production and pastures for grazing were key contributors with increases in both area irrigated and volume of water applied.

7.2 million megalitres were applied to Crops (69% of all water applied)

cotton: 2.8 million ML (up 7%) was applied to 359 thousand hectares (up 10%)
sugar cane: 1.0 million ML (up 4%) was applied to 212 thousand hectares (down 0.1%)
rice: 733 thousand ML (down 22%) was applied to 61 thousand hectares (down 26%)
fruit, nut, plantation and berry fruit: 939 thousand ML (up 12%) was applied to 156 thousand hectares (up 10%)
grapevines: 474 thousand ML (up 9%) was applied to 124 thousand hectares (up 1%)
vegetables: 399 thousand ML (up 3%) was applied to 99 thousand hectares (up 1%)

2.5 million megalitres were applied to Pastures (24% of all water applied)

pastures and cereals fed off: 1.8 million ML (up 18%) was applied to 604 thousand hectares (up 1%)
pastures and cereals cut for hay: 478 thousand ML (up 4%) was applied to 134 thousand hectares (down 13%)
pastures cut for silage:194 thousand ML (up 8%) was applied to 71 thousand hectares (up 5%)

Murray Darling Basin

More than two thirds (70%) of all Australian agricultural water use was within the Murray Darling Basin region in 2017-18.

In 2017-18 in the Murray Darling Basin

1.5 million hectares of agricultural land was irrigated (up 8%)
6.8 million ML of water was applied (up 7%)

Cotton and Pastures for Grazing account for more than half of the water applied in this region.

cotton: 2.5 million ML (up 4%) was applied to 320 thousand hectares (up 4%)
pastures and cereals fed off: 1.2 million ML (up 26%) was applied to 395 thousand hectares (up 8%)
cereal crops for grain or seed (excluding rice): 527 thousand ML (up 32%) was applied to 293 thousand hectares (up 53%)

Water expenditure and sources

Irrigation expenditure

Extra irrigation water purchased on a temporary basis reached a record level in 2017-18 driven by increases in New South Wales, Victoria and South Australia. The volume of water purchased also increased in these states.

In 2017-18:

$201 million of extra water was purchased on a temporary basis (up 86%) amounting to 1.7 million ML (up 36%)
$57 million of extra water was purchased on a permanent basis (down 27%) amounting to 122 thousand ML (down 13%)
The total cost of annual irrigation charges remained steady at $243 million
