Local media reported that Ramos-Horta had given a persuasive speech at Australia’s National Press Gallery on Wednesday.

Ramos-Horta said the project was vital to Timor-Leste’s future and one that could elevate his country to the “level of Dubai or Singapore.”

"This project will bring our country $50 billion in revenue and $50 billion as development benefits," said Ramos-Horta.

He described Australia as a neighbour who could make the “miracle” come true.

The development of Greater Sunrise gas field was initially stalled by the heated maritime boundary dispute pitting the neighbouring countries.

He promised to hold talks with Australian Prime Minister Anthony Albanese and deliberate on the project.

As much as the conflict was resolved, Timor-Leste and Australia are now in disagreement over piping the gas to a new liquified natural gas (LNG) plant in Timor-Leste or to the already set up LNG hub in Darwin as proposed by Woodside Energy Group, the project operator.

The Greater sunrise, which comprises two fields, was discovered in 1974 and estimated to hold about 5.1 trillion cubic feet of gas. It has 226 million barrels of condensate which have gas.

"It makes no sense piping the gas to Darwin that requires a five-hundred-kilometre pipeline instead of East Timor which will need a two-hundred-kilometre pipeline," said Ramos-Horta.

He further added that the operating costs would be less than in Darwin, and it would be Illogical to deny Timor-Leste  this golden chance.

Ramos-Horta also expressed confidence that they would reach a consensus with Woodside after discussion and that Indonesia, South Korea, Japan, and China were potential investors in the long-delayed gas project.
