Augusus Peoppel's corner

Poeppel Corner.
Augustus Poeppel (1839–1891) was a surveyor and explorer in Australia. He surveyed the borders between Queensland, South Australia and the Northern Territory.
Augustus Poeppel was born in Hamburg, Germany in 1839, the son of an architect. Emigrating with his family in 1849, he settled in South Australia.
Poeppel moved to Victoria to become a mining surveyor and architect. In 1878, after short periods in New Zealand and Western Australia, Poeppel joined the South Australian Lands Department and was soon appointed to the border surveys. He surveyed both Poeppel Corner (the point where the Northern Territory, Queensland and South Australian borders meet) and Haddon Corner (where the Queensland and South Australian borders meet).
During the Queensland-Northern Territory border survey, from the 142-mile post, he suffered from trachoma and lost 13 kg in weight, forcing his withdrawal in July 1885. His health was broken and he later lost sight in one eye.
Poeppel retired to Melbourne where he died in 1891 aged 52
In a cruel twist of fate, the post he'd planted was later discovered to be incorrectly positioned, as his measuring chain had been slightly too long. Still, Poeppel could be comforted by the knowledge that this remote location was named after him
Lawrence Allen "Larry" Wells (30 April 1860 – 11 May 1938), frequently spelled Laurence Allen Wells, was an Australian explorer
Wells was born at Yallum Station near Penola, South Australia and grew up in the Mount Gambier, South Australia district, and after a short stint in a merchants office, joined the South Australian Survey Department in October 1878. In 1883 the surveyor General, G.W. Goyder, offered him the Assistant Surveyor position to the Northern Territory and Queensland Border Survey Expedition, under Augustus Poeppel. This task took almost three years to complete, the honours of driving in the last peg being shared with assistant John Carruthers and Wells spent the next couple of years working in the far north of S.A. and the N.T., surveying pastoral boundaries.
