On October 2, 1824 Hume and William Hovell left Sydney to try and get to Spencer's Gulf in South Australia. The explorers took six servants, five bullocks, three horses and two carts. Much of the journey was over rough mountain country with many rivers to get across. On November 16 they found a ""fine river"" which they called the Hume. This river was later renamed the Murray River. They made a boat to get across the river near the present site of Albury. After a journey of 11 weeks, on December 16, 1824 they reached Corio Bay, Victoria near the present site of Geelong. Hovell made an error in his navigation, and they believed that they were on the shore of Western Port Bay. The journey back was made on path more to the west, the land was more level, and they were back only 5 weeks later. They ran out of food before the end of the journey, and the whole group was very, very tired.
