Hume and Hovell decided to make the journey at their own expense.
Some pack-saddles, clothes, blankets and arms were provided from the government stores.
The explorers left on 3 October 1824 with six men.
They reached Hume's station on 13 October, and on 17 October began the expedition proper with five bullocks, three horses and two carts.
On 22 October they found that the only way to pass the Murrumbidgee River, then in flood, was to convert one of the carts into a type of boat by passing a tarpaulin under it; the men, horses, and bullocks swam over, and everything was successfully got across.
A day or two later, in broken hilly country full of water-courses, they had great difficulty in finding a road for the loaded carts and decided on 27 October to abandon them.
Until 16 November their course lay through difficult mountainous country.
On that day they came to a large river which Hovell called Hume's River "he being the first that saw it".
This was an upper reach of the Murray River so named by Charles Sturt a few years later.
It was impossible to cross here, but after a few days a better place was found, and constructing the rough frame of a boat, they managed to get across.
By 3 December they had reached the Goulburn River, which they were able to cross without a boat.
During the next 10 days much difficult country was traversed but they then came to more level and open land, and on 16
December they sighted Port Phillip in the distance.
Presently they skirted its shores south-westerly and came to what is now Corio Bay near Geelong.
Here Hovell made a mistake of one degree in calculating his longitude, and they came to the conclusion that they were on Western Port.
The party returned on 18 December and wisely keeping more to the west had an easier journey.
On 8 January 1825 they came to the end of their provisions, and for a few days subsisted on fish and a kangaroo they were able to shoot.
On 16 January 1825 they reached the carts they had left behind them, and two days later came to Lake George.
