Robert George Thomas

Robert George Thomas FRIBA (16 February 1820 – 14 April 1883) was a draftsman and architect in the British colony of South Australia.

He copied Surveyor-General Colonel William Light's original plan for the City of Adelaide and was later responsible for the design and execution of some of its significant buildings, including several churches in a Gothic style.

His parents and brother William Kyffin Thomas were also in the "First Fleet" aboard Africaine, to set up the colony's first newspaper, the South Australian Register, and print the Government Gazette.

Thomas worked as surveyor and architect in Newport, Monmouthshire; he designed the Gothic entrance to the Cardiff Cemetery, and its Mortuary Chapels, and a Masonic Hall for the use of the Silurian Lodge No.

They returned to Adelaide aboard the Eizabeth Ann in June 1861, after a rather long passage of 101 days, towards the end of which Mrs. Thomas gave birth to a boy.

[10] Thomas's first big contract was for design and oversight of the new Flinders Street Baptist Church,[11] where the first service was held in April 1863.

[15] His achievements during this time include the Supreme Court building, the Magill Orphanage, Mount Gambier Hospital, the Sailors' Home at Port Adelaide, and the Parkside Lunatic Asylum and oversaw construction of the General Post Office, designed by Wright, Woods & Hamilton.
