âIâm just at the end of my tether trying to hold it together ⦠but Scott, my partner, and I have other jobs and income, we can rebuild. There are people out there with a lot more riding on this.â One of those people is Ben Storer, a farmer from near Walgett, nearly 300kms north of Dubbo in north-west NSW. The mice wiped out a full 800 hectares of his sorghum crop and have caused upwards of $200,000 in damage. âWe never even stuck a [havester machine] into those fields⦠we didnât even touch it, the mice had just ripped through it,â he said.
