Thomas Desmond was tried in Tipperary and sentenced to transportation for life. He arrived in the colony on the Atlas on 30th October 1802.
His first offence reported in the Sydney Gazette was just eight months after arrival when he was sent to the Gaol Gang in Sydney for drunkenness and insolence.
He later kept company with some of the most degenerate and callous prisoners in the colony and became a notorious runaway. Some of his exploits were reported in the Sydney Gazette over the next few years. After absconding from Newcastle with Richard Parsons in 1816 he seems to have disappeared. Richard Parsons later achieved fame as one of the men who discovered the Brisbane River
1803......A complaint was exhibited before the Magistrates against Thomas Desmond, for drunkenness and insolence to his master, and he was in consequence ordered into the Gaol Gang. - SG 10 July 1803
1804......Thomas Desmond, a prisoner confined in the Goal Gang, was last week punished with- 50 lashes for disobedience of Orders, and refusing to comply with an instruction calculated to the preservation of health and the comfort of persons so confined. SG 8 April 1804
1804......Mr. Thomson has succeeded in getting off the Speedwell, formerly Grono. This was effected on Wednesday and on Thursday she sailed for Hawkesbury from Broken Bay, the spot of her misfortune and recovery; the damage sustained to the vessel comparatively trifling. Mr. T. at some distance from the assistance of any of his people perceived among a body of natives a white man, nearly if not entirely naked, in whose person he soon recognized that of Thomas Desmond, now a fugitive from King's Town. Had it not been that the natives were aware that upon calling aloud the people employed in getting off the boat would come immediately to his aid, the rash adventurer would certainly have perished beneath their merciless hands, after encountering all the inconceivable distresses consequent on an improvident travel through the uncultivated country. So far from resisting Mr. T's command to surrender himself, he appeared happy in the occasion that presented itself of escaping the barbarity of his first captors and was in consequence sent round to Hawkesbury by the Speedwell, under charge. 9 December 1804
1804......Thomas Desmond mentioned last week to have escaped from King's Town, and picked up by Mr. A. Thompson near Broken Bay, was ordered to work in the gaol gang until an opportunity offers of returning him to the above settlement. The offender once before fled from thence, and endured excessive hardship before by happy accident relief was offered to him. He was then ordered to be returned, as was the case; and what he endured in his distressing travel operating in his favour, his punishment was lenient. Repeated offence, however, forfeits every claim to humanity, and Justice will a length assert her own prerogative. 16 December 1804
1805......Thomas Desmond, a prisoner that has repeatedly absented himself from the settlement at Newcastle, and under all the vicissitudes consequent upon so dangerous and precarious an enterprise thrice made his way into this settlement, is at the present moment in close custody in order once more to be returned to the place from whence he fled. The turpitude of this inflexible and audacious fugitive obstinately determines him to oppose every authority that may be exercised in the lenient punishment of his offences, which by a perverse conduct still aggravated, the necessary retribution is of course proportionally augmented. Having thus frequently braved the rigours unfortunately indispensable to the security of society and the maintenance of a mild subordination, the sanguine hope of his reformation cannot be entertained; yet the measure judiciously adhered to of remaining so refractory a character, will, it may be hoped, have its desired operation upon the less callous mind, and by the efficacy of example inform the unfortunate who may labour under the immediate displeasure of the law, that the participation of indulgence is attainable by those alone who by amendment endeavour to deserve it. - SG 21 April 1805
1805......Desmond, whose determined hardihood has repeatedly drawn upon him those rigours to which the vicious wantonly expose themselves, is again a fugitive from the settlement at King's Town, and ranges about the skirts of these settlements in company as is supposed with another of the name of Crisp and a third who is a German. 24 November 1805
1806......On Wednesday Thomas Desmond was brought in after his long absence from Government Labour at Newcastle. By his own account he appears to have been for some considerable length of time in the employ of a settler in the district of Hawkesbury, respecting which His Excellency has directed an enquiry to be made. 2 February 1806
1806......At a Bench of Magistrates convened on Wednesday the 5th instant several settlers were brought forward to answer to a charge of giving employment to Thomas Desmond, a prisoner absconded from public labour and repeatedly advertised. Three were fined in the sum of £5 each to the Orphans; and Joseph Wright in the sum of £20; but from lenient motives the Bench were pleased to remit the one half the latter penalty. It is needless to remark on the consequences of an indiscretion to which the Magistrates have on all occasion s testified a just aversion. The plea in such cases let up in extenuation by the defaulter cannot possibly obtain; for although it may be supposed natural that the fugitive should attempt by imposture to obtain assistance and employment, yet no evasion whatever can surmount the act of disobedience to a salutary Regulation, which requires that no person shall be employed until he has produced his certificate of pass, if a freeman, or his ticket of permission if a prisoner off the store. SG 16 February 1806
1813......Whereas Thomas Desmond, my hired servant, under an indenture the tenor of which is unfulfilled, has absconded, and is now absent from My Farm: I do therefore desire that no person will give employment or maintenance to the said Thomas Desmond, on pain of rigid Prosecution,.. Thomas McKenna, Hawkesbury. 23 January 1813
