According to The Australian Financial Review, the spike in demand in the region is attributable to confidence in its ability to cope with climate change, as well as demand for properties with reliable water supplies.

AFR reports that notable recent sales include:

* 36,000ha Nonda Plains, Julia Creek, for $12 million;

* 5340ha Grosvenor Downs, Moranbah, for $10.5m;

* 4599ha Logan Downs, Clermont, sold for $6.8m;

* Lochiel, Emerald, sold for $12.2m in May; and

* 12,200ha Lisnalee, Tambo, sold for $10.2m.

Elders agent Lorin Bishop told AFR that much of the demand had come from buyers chasing secure water.

"I think the north (of Queensland) has been neglected for a while and now people are starting to value the more reliable rainfall," Mr Bishop said.
