QGC has awarded a A$70 million pipe supply contract to Tyco Water, a wholly-owned subsidiary of Tyco International.
Tyco is supplying carbon steel, concrete-lined trunklines and pipe fittings to support water gathering in QGC's gas fields in the Surat Basin.
QCLNG senior vice president Alexander Nairn said Tyco had sourced all materials from Australian suppliers, delivering a significant boost to local manufacturing.
"Tyco has ordered 20,000 tonnes of steel and 10,000 tonnes of cement mortar," Mr Nairn said.
"The steel is being supplied by Australian firm BlueScope Steel and the sand and cement is being sourced from suppliers local to Tyco's production facilities at Wacol in Queensland and Somerton in Victoria."
Tyco is expected to employ an extra 100 people and has increased production from one to two shifts at its Wacol factory to accommodate the contract.
The finished pipes and fittings are being carried to QGC's gas fields by local transport companies.
The trunklines are used to move water from regional ponds to QGC's central water treatment plants.
