One hundred and thirty four convicts from counties in England were embarked on the 'Hercules', many from the York and Leviathan hulks on 7th December 1824.
The Guard consisted of a detachment of 41st and 48th regt., under Lieut. Stewart.
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. The 'Hercules' finally set sail on 9th January 1825.
Cape of Good Hope
The 'Hercules' was at the Cape of Good Hope by the 17th March 1829.
While at the Cape they were alarmed when Private John Green accidentally shot himself through the wrist. On the sound of the gun discharging the Guard and Seamen all under arms and believing convicts were escaping rushed to the deck to contain them to find only the injured soldier on deck and the convicts all safely locked in their prison.
They departed from the Cape on 29th March 1825.

The Australian reported on 12th May - 'The Venerable the Arch-Deacon who arrived in the Hercules, landed very properly like other people. Some silly folks imagined that his Venerability intended to disembark with public honours by 'roar of cannon' and by 'beat of drum'. Mr. Rossi, the new Superintendent of Police with his Lady and two children has arrived on the Hercules. He speaks English very well, but with a foreign - an Italian accent'.
Surgeon Michael Goodsir
Michael Goodsir kept a Medical and Surgical Journal from 26th November 1824 to 10 May 1825. He reported that it was a quick passage with favourable weather -
'I have been fortunate in having very few sick. The few cases I have had are common to every climate. I lost only one man during the voyage, he had been for many years sick with asthma and a ruined constitution when he came on board. From the confinement of the prisoners and consequence want of exercise, purgative medicines were often required and my principal expenditure has been on them'. 
The prisoners were landed on Wednesday morning 11 May 1825 and underwent an inspection by Governor Brisbane. Their healthy appearance gave every indication of the kind treatment experienced during the voyage.
