The Earl Grey
was built at Newcastle in 1835. She transported convicts to New South Wales in 1836
and 1838 and to Van Diemen's Land in 1842.
The prisoners were convicted in counties in England, Scotland and Wales - Derby, Stafford, London, Bucks, Warwick, Worcester, Somerset, Leicester, Chester, Lancaster, Bristol, Salop, York, Kent, Hertford, Lincoln, Gloucester, Essex, Nottingham, Devon, Huntingdon, Norfolk, Surrey, Northampton, Monmouth, Carmarthen, Montgomery, Denbigh, Inverness, Edinburgh, Glasgow, Dumfries, Stirling, Aberdeen and Perth. One prisoner had been tried at Antigua. There were also several former soldiers who had been court-martialed at Chatham and Barbadoe. 
Many of the prisoners of the Earl Grey had been held in prison hulks prior to embarkation. Select here

The Earl Grey
departed Deptford for Woolwich on 18th July 1838. At Woolwich 180 male convicts were embarked and at Sheerness another 110.
Passengers included Mr. Laurie of the Ordnance Department.
The guard consisted of Captain Ainsworth, Ensigns Dowton and Skerry (or Skurrie), 2 sergeants, 1 corporal and 29 rank and file of the 51st regiment, 10 women and 6 children. Members of the band of the 51st also arrived on the Earl Grey
Members of the 51st regiment who received medical treatment from Alexander Nisbett included
SURGEON ALEXANDER NISBET
Alexander Nisbett kept a Medical Journal from 5 July 1838 to 28 November 1838. He was well experienced on convict ships having already served on the convict ships Minerva
1828 and Asia
1830. He considered the Earl Grey
, to be a large roomy ship well suited to the service, but with 290 prisoners she was rather overcrowded.
He set about organising sleeping arrangements for the men. There were 'standing berths' for 234, leaving 56 to be accommodated in hammocks in the centre of the prison. In the hot weather those sleeping on hammocks slept on the prison deck to ensure that air could circulate in all directions. 
They were delayed a day in the Downs before proceeding down the channel and remained at Spithead for four days because of wet, windy weather. 
The Earl Grey
departed Portsmouth on the 8 August 1838
There were regular inspections and only those who kept themselves clean were relieved of their irons. The prison deck was cleaned every day with sand or dry stones, never wet, and airing stoves were kept burning, even during the hot weather. Windsails were kept down each hatchway and the chloride of lime used every day. Nothing but the most indispensable utensils were kept in the prison.
Half the convicts were on deck at a time, performing light duties for the ship or taking air and exercise, whenever the weather permitted. Those below were formed into classes for reading, writing and arithmetic, supervised by an officer. At sunset all prisoners were allowed on deck, and the surgeon had provided musical instruments for singing and dancing and there were theatricals as well.
Alexander Nisbet never had occasion to limit or regret this indulgence and found it provided excitement that all the men looked forward to. No corporal punishment was inflicted during the voyage, milder punishments proving adequate.
The convicts were generally healthy. Catarrh, diarrhoea and a few ulcers were present in the early part of the voyage. After crossing the equator and getting into the South easterly trade winds there were a few cases of mild fever and while running down the Easting between the Cape of Good Hope and New Holland the fevers became more numerous but remained mild. The winds became unfavourable as they reached the longitude of New Holland and the sick list rose to over thirty and scurvy began to affect the men. Sickness abated after about a week when the weather improved. In all there were only four days on which the convicts were entirely confined below deck because of bad weather.
Two convicts died on the passage out - John Brow aged 54 died on 2nd November. He was lame from a club foot. Had been on the sick list for several weeks to enable him the hospital diet. The surgeon considered his death unexpected as he had been improving in health; and George Morris died on 19th November aged 36. His death was to have been expected, he had a cutaneous eruption and repeated attacks of diarrhoea with a voracious appetite, eating anything edible he could get. The immediate cause of his death was thought to be a relapse brought on by eating a large quantity of imperfectly boiled peas. 
The Earl Grey
arrived in Port Jackson on 21st November 1838.
The convicts were landed on Tuesday 27th November 1838.
DEPARTURE FROM PORT JACKSON
In December it was reported that the Earl Grey
was expected to leave for China as soon as she discharged the iron water pipes she had brought out and loaded some ballast. She would have been delayed in getting under way however after a collision with the whaling vessel Pocklington
in the harbour.
