The MPS allows access to the Major Projects Facilitation Agency, collaborating with state and territory governments to expedite approvals for projects aligned with national strategic priorities, the filing said.

In addition, the MPS supports the pathway towards a final investment decision targeted by year-end, with first production expected by the end of 2029, per the filing.
