It was reported on 18th December 1824 at Portsmouth of the detention of many outward bound vessels by contrary winds. Some of the ships had been two months out of the Downs during which they had made repeated ineffectual struggles to clear the Channel but could not get to the westward of Plymouth. The convict ships Hercules, Royal Charlotte and the Asia were among these vessels detained at Portsmouth.
Departure from Portsmouth
The Asia departed Portsmouth on 5th January 1825. She called at Santa Cruz on 24th January.
The Guard consisted of Lieut-Governor Colonel Stewart of the 3rd regiment, Lieut. Thomas Bainbridge* of the 57th and 54 men of the 57th and 3rd (Buffs) regiments in including Sergeant Pike and Private John Finn.
Arrival in Port Jackson
The Asia arrived in Port Jackson on Friday 29 April 1825.
A muster was held on board by Colonial Secretary Frederick Goulburn on 2nd May 1825. Of the two hundred prisoners who were embarked in England, one was re-landed prior to sailing, two men died on the voyage Thomas Howey and James Lovett - and one was sent to the hospital on arrival in Sydney Cove.
The three youngest convicts were George Hames (16), William Miles (16) and James Quinnell (15). Hames and Quinnell were both sent to Carter's Barracks on arrival. Convict Robert Johnson, surgeon and apothecary was sent to the Valley of the Swells, Wellington Valley.
Surgeon Thomas Davies
There were no cases of scurvy on this voyage and the surgeon was pleased to report that there were no cases of illness when the vessel entered Port Jackson........
It may not excite surprise that my anxiety to prolong the existence of men so circumstanced has been great and continued and I beg to remark that in every individual requiring even a purgative and the facility with which the greater number were restored to their former condition, may be conclusive as to the slight tendency of their indisposition to danger. In conclusion I had the satisfaction of discharging my charges in the Colony perfectly healthy.
