Mackay isn't on either Queensland gas distributor's reticulated network, so LPG is the standard gas supply, and the same statewide compliance certificate rule applies.
If you searched for gas compliance certification Mackay rather than gas compliance certificate, you're looking for the same document, just different phrasing. Queensland's Petroleum and Gas (Production and Safety) Act requires the person doing the work to give "a certificate in the approved form", not a certification.
Mackay doesn't appear in the published coverage areas of either of Queensland's reticulated gas distribution networks (Australian Gas Networks' Brisbane and Rockhampton/Gladstone regions, or Allgas' Brisbane, Gold Coast and Toowoomba regions), so most homes and businesses in the area run on LPG rather than piped natural gas. That doesn't change the compliance rule: an LPG installation still needs a gas compliance certificate from a licensed gas fitter, issued and lodged through the RSHQ Portal the same way a natural gas job would be.
See our LPG gas compliance certificate QLD guide for what's different about a bottled-gas installation, including the distinction between a swap-and-go exchange cylinder (no certificate needed) and a fixed LPG installation feeding a house (certificate required, same as reticulated gas).
Whether you're installing a new LPG system, replacing a gas hot water unit, or confirming an older Mackay property's gas fitting is still sound before a sale, the licensing and certificate requirements are identical to anywhere else in Queensland. Start with our main QLD gas compliance certificate guide for who must issue it and when.
Typical gas compliance certificate cost in QLD
$180–$250
stand-alone certificate, plus any service call fee
Compiled from published pricing at Crew Plumbing (crewplumbing.com.au) and Energy Trade Solutions (ngtradesolutions.com.au), checked live August 2026: from $180 for a stand-alone certificate on an existing system, up to around $250 where a new appliance is installed and certified at the same time.
Queensland's QBCC gasfitting trade licence and RSHQ gas work licence/authorisation don't carry a stated public liability insurance condition: QBCC's published licence eligibility requirements cover technical/managerial qualifications, financial requirements and, for some licence classes, professional indemnity insurance, not public liability cover. It's worth asking to see a current certificate of currency before hiring rather than assuming it's a licence guarantee.
