Our Team
Our History

Mannion Drilling are a private family run company, with a history that dates back over 100 years. Our Company Director, Jason Mannion, is a fourth generation driller with over 30 years of drilling experience and knowledge.

1920

While an exact date cannot be traced as to when Charles Cox first started drilling, it is estimated to be just after his discharge from the First World War Charles married Rosina Rettke and they had four sons and three daughters and at one stage all four sons and three son-in-laws were drilling in Queensland and Northern NSW.

Daughter Ivy (Mannion) recalled from her early childhood that Charles had a thrashing machine which was driven by a steam-traction engine, and this was taken from property to property helping the farmers with their harvest. Her first memories of a drilling rig were in the early 1920s when Charles operated his rig in the Morven area, but it could well have been earlier.

Charles had the distinction of owning the first T-model Ford in the Freestone area, on Queensland’s Darling Downs. Charles and Rosina’s eldest son Albert (Jack) was a drilling contractor at Moree and sons Ray and Greg were also drillers for a time. Their second son, Charles (Bill) Cox drilled around the Warwick area. Mervyn (Snow) worked with his father in Queensland and northern NSW and eventually settled at Quirindi. The youngest son Ron was at Boggabri and one of his sons, Malcolm was also drilling for a while.

Charles and Rosina’s eldest daughter Daisy married Arthur (Larl) Shelley and they settled at Goondiwindi and their four sons Ken, Keith, Arthur and Ian were also driller’s. The second daughter, Ivy married J.W. George Mannion and he was a driller and four of their six sons at one staged worked on the rigs. Sons Mervyn (Curly) and Leonard (George) worked with Snow Cox, eventually taking over his business.

Ivy and George’s second son, Neville, based himself in Delungra, where Neville taught Jason from a very young age the in’s and out of drilling. The youngest daughter, Myrtle, married John Shelley and they too settled at Goondiwindi and their two sons Lionel and Arthur were drillers, whilst Lionel’s two sons Bob and Kevin were also drilling in Queensland.

Jason Mannion purchased the business from his parents, Dorothy and Neville Mannion in 2000, Four years later, Jason and Jacinta married and built the workshop at Inverell that same year. In 2005, Jason and Jacinta welcomed the 5th Generation of Mannion Drilling, their son, Mitchell Mannion. The next year, they celebrated the safe arrival of identical twin daughters Grace and Zara and purchased a brand-new rig, a THD25 Bourne drill.

The family relocated to Gunnedah in 2011 to expand operations, three years prior to Neville’s passing, and moved into the Mannion Drilling purpose-built office and workshop in 2017, while 2020 proved to be a huge year with the purchase of a MD65 Hands Free Drill Rig, and just a few months after that, the acquisition of Gricks Drilling, where they expanded operations throughout the region of Mudgee. Extensions to the office were completed to accommodate the expansion of the business.

Today

While textbooks can be written about drilling techniques and advances made to rigs by modern technology, many interesting stories can be told by the Cox family members about drilling – from the deep holes in the Great Artesian Basin, to the Gulf and down into the thick gravel beds producing irrigation water in the Namoi Valley, and now coal exploration is the “buzz” word.
