 On 11 October 1864 the combined party led by Frank Jardine started out from Carpentaria Downs.It consisted of Frank, his brother Alex, three stockmen, a surveyor, four Native Police troopers, 42 horses and 250 head of cattle.The trip took another five months during which time the party was constantly opposed by the area's Indigenous inhabitants as they forced their way through scrub and swamps and crossed at least six large rivers, including the Jardine River which was subsequently named after the brothers.
