Dennis Murphy RPEQ.
RPEQ-registered electrical engineer and founder of Beetle Engineering & Automation. Based in Mackay, delivering control system engineering across Queensland's industrial sector since 2024.
Dennis Murphy is the principal engineer at Beetle Engineering & Automation, with a career in the mining and sugar sectors dating back to 2000. He holds a Bachelor of Engineering (Electrical), is RPEQ-registered, and is a Member of Engineers Australia on the National Engineering Register (MIEAust NER), as well as a member of the Australian Information Security Association (MAISA).
His engineering work spans industrial automation, PLC and SCADA systems, electrical design, OT systems administration, and control system integration. He has worked on plant across the full range of Central Queensland industrial operations - Bowen Basin mine sites, Burdekin, Pioneer Valley and Tableland sugar mills, Mackay manufacturing operations, and regional water and utilities infrastructure.
His water sector experience includes treatment plants at Kenya, the Bundamba desalination project, and the Proserpine and Airlie Beach water treatment plants in the Whitsundays.
His project experience extends beyond Central Queensland - the George Fisher mine at Mount Isa, iron ore mines and ports in Western Australia and South Africa, bulk materials handling at Hay Point and Dalrymple Bay coal terminals, and gold and copper process plants in Laos. Across his career he has electrically and control system commissioned over 30 yard machines including stackers and reclaimers.
Career highlights include his first mine site trip in 2000, getting on board the DL35 dragline at Norwich Park (since closed); being flown into a remote Bowen Basin site in a two-seater aircraft - just him and the pilot - to deliver a replacement CPU for a failed unit at a coal mine CHPP and get the plant running again; being on site for first iron ore on ship at Andrew Forrest's new iron ore port in Western Australia; being on site for first coal on train as part of the full automation of the train load-out for the new Carmichael coal mine in western Queensland; and flying around 100m above the jungle by helicopter to reach a gold mine in Laos.
That combination of electrical registration, automation experience, and information security membership shapes how projects are scoped and delivered - from control system design through to the security considerations of connecting plant to wider networks.
RPEQ registration can be verified through the BPEQ public register at bpeq.qld.gov.au. Registration details are publicly available and updated by the Board.
Compliant by default
Significant electrical modifications on industrial plant in Queensland require RPEQ engineering sign-off under the Electrical Safety Act. Work delivered by Beetle Engineering meets this requirement.
No separate certifier
Clients do not need to engage a separate registered engineer to certify the design. Engineering, programming, commissioning, and RPEQ sign-off are all handled in-house.
Faster project delivery
Having the RPEQ on the engineering team removes the coordination overhead of involving an external certifier. Sign-off happens as part of the project, not after it.
Less common platforms - ask. We have worked on a range of systems outside this list and can assess capability before committing to a project.
