Highlights

Amplitude made a development-phase final Investment decision on its East Coast Supply Project in September 2026.
The Otway Basin project targets gross gas output of up to 90 terajoules daily from 2028.
The company indicated net development spending of AUD 190 million to AUD 210 million over FY27–FY28.
Drilling, subsea works and regulatory execution remain necessary before first gas.

Amplitude Energy Limited (ASX:AEL) is an Australian oil and gas company supplying domestic energy markets, with activities in the offshore Otway Basin and associated infrastructure in Victoria. Its East Coast Supply Project is designed to connect additional gas fields with existing processing facilities. During 2026, the company moved the development phase through a final investment decision, bringing capital expenditure, drilling and construction delivery into sharper focus.

East Coast Supply Project Scope

The East Coast Supply Project combines offshore field developments with the established Athena gas plant and associated infrastructure. Amplitude Energy Limited (ASX:AEL) has described this as a brownfield approach: existing facilities are intended to handle additional gas rather than requiring an entirely new processing network. That approach does not eliminate subsea installation, modification, approvals or operational risks.

The development plan involves the Annie, Juliet and Artisan gas fields, while the Nestor prospect is a separate exploration opportunity. A prospect that has yet to establish commercial resources should not be included as guaranteed supply. The company is pursuing the project with a joint-venture partner, and gross field output should be distinguished from Amplitude’s attributable share.

September Development Decision and Target Volumes

On 30 September 2026, Amplitude Energy Limited (ASX:AEL) announced a final investment decision for the development phase. Its stated target is gross production of up to 90 terajoules per day from 2028. The expression “up to” is important: it is an objective based on project assumptions rather than an already measured production rate.

The decision authorised development activity, but the timing of first gas still depends on successful drilling and tie-in work. Producing fields, contingent resources and exploration prospects are different classifications. Any eventual reserve reclassification must meet the applicable technical and commercial criteria rather than follow automatically from approval of capital spending.

Capital Programme and Gas Sales Arrangements

Amplitude Energy Limited (ASX:AEL) estimated point-forward development costs of AUD 190 million to AUD 210 million net to its interest across FY27 and FY28. The programme involves subsea facilities, engineering and modifications to the gas-processing network. The spending range remains an estimate; final outlays could vary with contractor performance, field conditions and delivery schedules.

The company has described gas sales arrangements supporting future East Coast Supply Project volumes. Such agreements help define prospective demand, but contracted sales do not replace the requirement to complete and commission the offshore development. The commercial outcome will also depend on production reliability, field decline and operating costs once the infrastructure begins handling new gas.

Annie Drilling and Remaining Risks

The 2026 drilling campaign includes the Annie development work, following activity at Juliet. The company’s planning materials describe Annie-2 as a well intended for drilling, testing, completion and suspension or shut-in as appropriate. Amplitude Energy Limited (ASX:AEL) also sanctioned an exploration well at Nestor; any future contribution from that location depends on the outcome of drilling and subsequent development assessments.

Offshore construction can face weather interruptions, equipment constraints, permitting requirements and unexpected reservoir behaviour. The project also depends on synchronising field readiness with plant modifications and pipeline works. The 2028 target should therefore be evaluated against disclosed milestones and updated reserves information, not treated as certain commercial delivery.

Key Insights

Amplitude Energy Limited (ASX:AEL) has approved a development pathway for additional Otway Basin gas supply and set a target for first output from 2028. The outcome remains dependent on drilling, construction, regulatory work and commissioned infrastructure.
