Robert Dickson kept a Medical Journal from 30 June to 3 December 1833. Several of the Guard and seamen had become ill with cholera while on the voyage from Deptford to the Cove of Cork and Robert Dickson delayed the embarkation of the convicts until the vessel was fumigated and clear of the disease.
Convicts and Passengers Embarked
On 22nd July at Cork two hundred convicts were hurriedly embarked on the Java.
At the same time four free settlers came on board - John McNamara, Michael McNamara, Patrick McNamara and John McNamara. There were also seven women and 10 children.
Six military convicts were also embarked on the Java. Five of them were Robert Deighton, Michael Fox, James Fraser, Hugh McQuiggan and Edward Standford.
The Guard consisted of 29 rank and file of the 4th, 17th and 21st regiment, 5 women and 4 children under orders of Lieut. Wrixon, 21st Regt. Passengers Mrs. Wrixon, Ensign Codd, John Wrixon. 
The Java departed Cork on 24th July only two days after embarkation of the prisoners, probably because of the fear of cholera being brought on board.
The crimes of the prisoners of the Java were mostly various forms of theft - stealing clothes, a heifer, a horse, money, mail, sheep, pigs, pick pocketing, house robbery, etc., however there were also several men convicted of the more violent crimes of rape, manslaughter, murder, malicious assault and attacking a house.
There were also Whiteboys who had been convicted of administering unlawful oaths. About twelve convicted of this crime had come from Kilkenny where there was much unrest.... - Thomas McDonnel, Edward Moylan, William Lalor, John Holohan, Michael Griffen, Patrick Fitzpatrick, William Fitzpatrick, Michael Comerford, John Cantwell, Martin Brennan, James Slattery Kilkenny and James Whelan were all tried on 15th March 1833 at the Kilkenny Assizes and sentenced to transportation for life.

Surgeon Robert Dickson
Three of the convicts were already ill when the Java set sail. John Sullivan a boy of thirteen was also unhealthy but rallied and was eventually landed in a healthy state although still delicate.
Robert Dickson attributed the cause of so many bowel complaints during the voyage to the sudden change from dry heat to cold moisture and choking perspiration. He thought them ill fed compared to English prisoners and therefore unable to withstand the long passage and changes of climate. He also noted in his journal the inadequacy of the clothing supplied to the convicts....There were not enough corduroy jackets and the trousers were unlined.
There were several deaths -
Thomas Adams age 15 died on 17 October;
Patrick Burke on 8th October;
Robert Polly age 19 on 11 October;
James Crawley age 19 on 30th October;
Michael Bercury on 15th October.
In his Medical Journal Robert Dickson refers to the system of payment of surgeons -
Several Naval Surgeons have boasted of their great success in taking out convicts without losing a man; nay they have printed it - I shall not shrink from comparing Professional testimonials (now in my possession) with the vainest of these Gentlemen, yet, I lost four men, on the passage, and one the Day after the ship arrived at Sydney. (*this was John Connolly) Had this fifth man been sent to Hospital and died in the dockyard, or died in a cart, going up to the hospital - as too many have done; I should have gained the sum of 10s 6d, further I was advised to send this man to Hospital instantly but I am not yet so poor as to sell my humanity for 10s 6d. To prevent a recurrence of this indecent, unprofessional, inhumane, unchristian like practice, would it not be well to pay surgeons for all those whom they brought into Sydney, or Hobart Town? 
In the latter half of the voyage they experienced much wet, foggy weather which saturated the decks, clothes and everything that moisture could reach. The Java arrived in Port Jackson on 18 November 1833 after a voyage of 117 days.
The prisoners were mustered on board on 22nd November 1833. - The indents reveal that five had died at sea and four had been sent on shore sick at Sydney.
There is no indication in the indents as to where the convicts were assigned on arrival.
2). Convict Michael Lawless a one-armed cooper from Kilkenny was not long in the colony. He was hung as a bushranger in June 1834 after absconding from the Phoenix Hulk with several others and robbing various properties in the Botany Rd area.
3). Assize Intelligence - Kerry Assizes - The following are the convictions which have taken place at the Kerry assizes: Michael Meenehan, manslaughter, to be transported for life - Garret Lynch, pig stealing, seven years transportation - Michael Berkely, larceny, seven years transportation - Patt and Darby Foley, sheep and goat stealing seven years transportation; John Foreham sheep stealing, seven years transportation....The prisoners Meenehan was a schoolmaster; a child of nine years old, a son of the deceased, was one of his scholars - The first day the child went to school the prisoner beat him most unmercifully, so that the child on his return home was found beaten black and blue and shockingly welted. Cornelius Neill, the deceased, called the next morning on the prisoner and told him he would carry him before the parish priest for his cruelty to his son, and while laying his hand on the prisoners' shoulder for that purpose, the prisoner stabbed him in the side with a penknife, of which wound Neill died in a few days after.
4). Queens County Assizes - Maryborough, Wednesday, March 15 - .....Patrick Ryan and John McManus, for serving a threatening notice on Thomas Copeland at Deerpark, for the purpose of inducing him to give up his land - Guilty. Seven years transportation - Freeman's Journal 19 March 1833
