I recall the mouse plague of ’75 in the same area – stretching 100s of kms from Eyre Peninsula across the Nullarbor to Eucla. I was driving with my brother across to Perth to take up my first ministry post. We left Ceduna at dusk. The road was nothing but a seething mass of mice until midnight. At Eucla we threw our sleeping bags down on the ground in an area enclosed by an electric boundary to keep the mice out. An hour later it shorted and mice were swarming over us. Nothing for it but to get up and keep going. One of those surreal experiences. The link to climate change? Best tap on the heading and read the article.
