What a beautiful spot! We stayed 6 nights at a farm just outside Esperance which had toilets and shower, and happy hour on the deck every afternoon. Tom, the owner, is a butcher so we bought some organic meat off him (already vacuum sealed) for our trip across the Nullarbor.
I worked 3 days from the van, while we had great 4G coverage. The Great Ocean Drive was the highlight of Esperance. Absolutely beautiful coastline, beaches and bays all with bright blue water and very white sand. Also visited the Pink Lake and Stonehenge - an exact replica of the original in the UK.
