Where did Gregory explored?

Answer 1

Gregory Blaxland was one of the first three Europeans to cross the Blue Mountains. He, William Lawson and William Wentworth crossed via the ridges on a track that was almost impossible to find. This was significant because, after the colony of Sydney/New South Wales had been virtually imprisoned by the mountains for twenty five years, graziers and farmers were now able to expand out into new grasslands and agricultural lands.
