A trio of heavyweight unions will present a petition to the West Australian parliament, calling for an investigation into the use of local labour and suppliers at the Chevron-operated Gorgon gas project.
The Maritime Union of Australia, Australian Manufacturing Workers Union and Construction, Forestry, Mining and Energy Union renewed their call for more local jobs at the large project on Wednesday, saying local workers were missing out.
They've called for a parliamentary inquiry into Chevron and its suppliers to assess whether the 2003 Gorgon Gas Processing and Infrastructure Project Agreement with the state government is being complied with.
The MUAWA said the US energy giant and its contractors were not meeting their obligation to give preference to local labourers and material suppliers.
But a Chevron spokeswoman rejected the union claims.
"We will always give preference to the use of Australian labour, services and materials," she said.
