Recommended by a colleague at the Melbourne Hospital, Dr.
William Gillbee (a member of the Exploration Committee of the Royal Society of Victoria), and supported by Neumayer and Mueller (also members of the society), he was appointed to the
Victoria Exploring Expedition (VEE) at a meeting of the Exploration Committee on Friday, 13 July 1860, as both scientific and medical officer on a salary of £300 p.a. On 18 August 1860, he signed the Memorandum of Agreement at the Royal Society of Victoria.
Burke's erratic leadership of the
expedition which led to the resignation of his second-in-command,
George Landells, at
Menindee, triggered Beckler's resignation from the expedition. The resignation of Mr. Landells, and Burke's splitting the expedition in two at Menindee, meant that no one was in charge in Menindee. Beckler's resignation was accepted but he agreed to stay with the men and supplies left at Menindee, which were meant to follow and form a depot at Cooper's Creek. Waiting for a replacement and despite his resignation, Beckler stayed until the bitter end, fulfilling his original obligations to the expedition both as doctor and scientific observer. With the failure of the expedition, he was called before the commission of inquiry into 'the sufferings and death of Robert O'Hara Burke and William John Wills' in 1862. He found himself accused of betrayal and abandonment both in Australia and in Germany. ==Germany==
