Hulk Surprise (334 convicts), located at Cork
Hulk Essex (400 convicts) located at Dublin
Cork Penitentiary (females) (120 convicts).
The total of 854 prisoners noted in the Return is a little short of Charles Bateson total in The Convict Ships (845), but is close and may not account for those who were rejected by the surgeon as being too ill to survive the voyage.
Surgeon George Fairfowl
George Fairfowl kept a medical journal from 30th June 1830 to 31st December 1831..........
On the 30th June 1830, I was appointed to the convict transport the Andromeda taken up to carry 180 male convicts from Cork to New South Wales, and joined her the same day. The guard embarked next morning and on the 10th of July the ship moved down the river on her way to Cork where she arrived on 30th. During the passage the ship's steward was taken ill with small pox, but no unpleasant consequences resulted from it. He was sent on shore as soon as the ship anchored.
The examination of the convicts took place on board the hulk in the presence of the Superintendent of Convicts and surgeon of the hulk. It (the examination) is very unsatisfactory, for the men being anxious to get away, and the surgeon equally anxious to get rid of bad or troublesome cases both the parties from whom the naval surgeon expects to receive information are interested to conceal any symptoms of disease. While the squalid looks of the generality of Irish convicts at least of all those on board of the hulk while I was there, make it difficult from the mere look to discriminate so as to pick out every case of sickness. Many therefore were approved who ought never to have been brought forward for examination and even some of those whom I had rejected were embarked - a piece of disingenuity not found out until too late to be remedied. In a few days the numerous daily applications for medicine taught me to anticipate a sickly voyage. For the first six weeks we had no prevailing disease, although a vast number of cases were on the daily sick list. The most numerous were bowel complaints.
In August Edward Tyne from Tipperary was found to be ill with fever. He was sent on shore and a deserter William Kershaw was sent in his stead. 
The Morning Post reported on 28 April 1830 about some of the prisoners who were embarked on the Andromeda...
The Doneraile Conspiracy ......... Yesterday evening, at four o'clock, twenty five convicts from the County Gaol were escorted by a small party of the Scots Greys to the Waterloo steamer, lying at Merchants' Quay, to be conveyed to the Hulk Surprise at Cove, preparatory to transportation to new South Wales, for which purpose the vessels are shortly expected in our harbour. John Leary, Lynch, Magrath, Shine and Roche, the men convicted of the conspiracy at Donneraille, were of the number. They were all in the prison dresses, grey jackets and trousers, with leather caps. Leary, who was a respectable looking old man, of about seventy years had a fur cap on; previous to his going below in the vessel he took farewell of his daughters and one of his sons, during which he wept bitterly. It was afterwards ascertained that they had permission to go with him to the convict vessel at Cove, which afforded him some satisfaction. The other men did not say a word, except Shine, who made some protestations of his innocence, at the conclusion of which he looked around and said 'Farwell old Ireland for ever' and then went below. Shortly after the vessel proceeded down the river, amidst the lamentations of their friends.

The Andromeda departed from Cork with 180 male prisoners on 28 August 1830.
After six weeks the prisoners began to suffer dysentery and this continued for the rest of the voyage. George Fairfowl could not accommodate all the men in his hospital which was already partly occupied by men with chronic diseases who should not have been embarked. He was obliged to allow many suffering dysentery to remain in the prison where they had to care for themselves, a process he had little faith in.
The circumstance of ill conceived sanitary arrangements also added to the illness on board - Formerly these ships were fitted with water closets which having a constant supply of water, could be kept clean and wholesome all the 24 hours. In this ship these were exchanged for large iron buckets with covers loosely fitted, which could not be emptied and cleaned out during the whole night and notwithstanding every care that could be taken by having them emptied every night at ten o'clock washed clean and rinsed with a solution of chloride of lime, taken out of the prison early in the morning and kept upon deck all day with the exception of one which was indispensable for the out hospital sick, the prison was often a most offensive nuisance to a person coming from the fresh air. 
The Andromeda arrived in Port Jackson with 172 prisoners on 18 December 1830. Altogether eight convicts had died, four of them from dysentery.
The Colonial Secretary Alexander Macleay mustered the prisoners on board on arrival in the colony. Twelve were later sent to the hospital in Sydney.

Procellaria Capensis - This beautiful, but well-known petrel, was, of course, our constant companion on all occasions of our being at sea, and was particularly numerous off the entrance to the river Plata, feeding probably upon the exuviae that drift out with the current. One being taken with the hook, was killed, and in its entrails several small fragments of granite were found mixed with the half-digested food. A remarkable instance of the natural habits of this bird has lately come to my knowledge, which deserves to be recorded. The late Mr. George Fairfowl, surgeon R.N., on his return from New South Wales, in the year 1831, caught one of these birds, and let it go, with a ribbon tied round the body, by which it was easily distinguished; the bird was thereby observed to follow the ship, from day to day, for the space of 5,000 miles. ......Proceedings of the first expedition, 1826-1830, under the command of Captain P. Parker King
4). Limerick Assizes Monday March 15 - William Shelton for stealing 20 yards of linen from the shop of Mr. Abbott in Rutland street. The prisoner pleaded guilty and the Court sentenced him to three months imprisonment. Some time after he thus addressed the Court - Prisoner - I think you may as well transport me at once, my lord, for I won't be a week out, when I'll be in gaol again; and I'd rather be transported than two months in gaol. Court - Who is this person? Prisoner - I am Shelton my lord Court - I think I may satisfy him. He was then ordered to be transported for seven years. - Freemans Journal March 18 1830.

6). Clonmel Assizes - Curious Case - Thomas Tuohy and William Costigan were given in charge for a burglary and robbery in the house of the Rev. Alex. Hoops, rector of Newchapel. Rev. A. Hoops sworn - I am a Clergyman residing in this county - on Sunday evening November 3 about half past five o'clock (the dishes not having been removed from the dinner table), I heard a noise below stairs; the dog was barking; almost immediately my kitchen maid was forced into the parlour by five men,, two of whom were disguised, and four were armed; of any of the party I had no previous knowledge, but now know one off the - William Costigan one of the prisoners; (he was here identified). He it was who had the short gun; a demand for fire arms was made; I told them I had non; one off the party, addressing the man who persisted in saying that I had fire arms, sad, why don't you take the gentleman's word? They then commenced a search but before they did so, I was assured by one of them that if I had 10,000
pounds in the house, a penny of it would not be touched Court - Were they in earnest? - (laughter). Had you 10,000 pounds in your possession? Witness - II should be glad I had, my Lord, but not for their use; they proceeded with me up stairs, but used no violence; I opened all my drawers, but they discovered no arms; they then come down stairs, and in the drawing room one of the party asked me for money; I told them I had but 30s in my possession; Costigan, the prisoner, spoke rather roughly, and said, I must have more; I handed them the 30s note, soon after which they went away. I then directed the house to secured; about a quarter of an hour having elapsed, one of my servants came up stairs and told me the party were at the door and they they wanted to come in again; directed the door to be opened ; three men now entered,, and demanded whiskey; I opened the garde-du-vin, and while in the act of giving them a decanter of sprits one of the party approached the head of the dinner table and helped himself to one of the dishes; the cook also helped him after which he partook of some turkey (laughter) the remainder of which he afterwards took up and put it under his coat (laughter) I now handed them the whiskey, but they said they did not wish to put me to the expense of a decanter, and that a black bottle would answer them just as well; before they went off they observed that I was a good fellow (laughter). The prisoners were identified by several other witnesses and sentenced to transportation. - Belfast Newsletter 9 April 1830
