The Australia Pacific liquefied natural gas (APLNG) joint venture has begun drawing on its $US8.5 billion ($A8.25 billion) funding facility for its massive LNG project in Queensland.

APLNG on Monday said all conditions had been met for the facility which, the joint venture says, is the largest financing facility ever secured in Australia.

The first drawdown had already occurred and the facility would be progressively drawn upon during the $23 billion LNG project’s construction, it said.

The funding was secured in May from the Export-Import Bank of the United States, The Export-Import Bank of China, and a syndicate of Australian and international commercial banks.

APLNG is made up of Origin Energy, US giant ConocoPhillips and China Petrochemical Corp (Sinopec).
