Captain James Wallis was Commandant at Newcastle in 1818 when Governor Lachlan Macquarie visited the settlement.
The Sydney Gazette reported on 1st August 1818.....
'On Monday last the 27th ult. His Excellency the Governor and Mrs. Macquarie and Staff, embarked on the government Brig Elizabeth Henrietta for the Settlement of Newcastle on Hunter's river.
The vessel got under weigh between 2 and 3 o'clock with a fair wind, which continuing equally favourable during the night, makes it probable that she would reach the place of her destination by 9 the next morning.
His Excellency last visited Newcastle in 1812 when in its infant state, and comparatively of little importance, being chiefly appropriated for the reception of convicts whose delinquencies here had rendered them liable to extraordinary punishments. It was also resorted to for supplies of lime, coal, and timber for the uses of Government.'
Soon after Governor Macquarie's visit work was commenced on Macquarie Pier....
According to an article in the Australian in 1825 - There were no artisans appointed to superintend and direct its construction. The engineers at that time, and up to the time of the work ceasing, were subalterns of the 46th and 48th regiments, and totally ignorant of their duty - the mechanics and workmen generally, were under the orders of an old sergeant of the 46th regiment who was principal superintendent of public works and died at Newcastle. The overseers under him were two stonemasons, who, though good mechanics in their way, were totally unfit to carry such an important undertaking into effect. The work at the pier ceased entirely in the early part of the year 1823 read more in an article in the Australian written in 1825.
The Sergeant mentioned above was John Evans. He gave evidence before Commissioner John Thomas Bigge on 18 January 1819 -
