The Middlebrook Solar Farm is a proposed 320-megawatt (MW) solar farm and battery storage system located approximately 20 kilometres south of Tamworth. The project will be located between, but outside of, the New England and Hunter-Central Coast Renewable Energy Zones.

The project scope comprises construction of:

• a 320-MW solar farm comprising 750,000 solar panels
• a 320-MW / 780-megawatt hour Battery Energy Storage System
• an onsite 330-kilovolt substation, and
• other associated infrastructure.

Cross River Rail will provide an additional rail crossing across the Brisbane River.

The project involves:

• a new 10.2-kilometre rail line from Dutton Park to Bowen Hills
• 5.9 kilometres of twin tunnels under the Brisbane River and CBD
• four new high-capacity underground stations at Boggo Road, Woolloongabba, Albert Street and Roma Street
• eight rebuilt above-ground stations at Salisbury, Rocklea, Moorooka, Yeerongpilly, Yeronga, Fairfield, Dutton Park and Exhibition
• three new stations on the Gold Coast, and
• a new signalling system: the European Train Control System (ETCS).

The Cross River Rail project is being delivered through three major infrastructure packages of work:

• the Tunnel, Stations and Development (TSD) package (awarded to the Pulse Consortium through a Public Private Partnership)
• Rail, Integration and Systems (RIS) package (awarded to the Unity Alliance through an alliance contract), and
• the ETCS package (awarded to Hitachi through an alliance contract).

The Gippsland Offshore Wind Transmission Project will support the connection of offshore wind infrastructure in the Gippsland Offshore Wind Zone to the mainland grid. The project will run from a new connection hub on the mainland near the Gippsland coast, which will service offshore wind farm connections, to a grid connection point near Loy Yang Power Station. 

The proposed project comprises the development, construction and operation of approximately:

• 55 kilometres of 500-kilovolt transmission lines
• an onshore connection hub, including high-voltage substation plant and equipment, and
• a grid connection substation near the Loy Yang Power Station.

The project was formerly known as the Greater Gippsland Transmission Project.

The Federal and NSW Governments are funding upgrades to Elizabeth Drive, which runs between the M7 Motorway at Cecil Hills and The Northern Road at Luddenham. The road is approximately 14 kilometres long and runs parallel to the proposed M12 Motorway. This project would provide additional capacity in a growth area surrounding Western Sydney International Airport.

The proposed project would provide two lanes each way, a median island, landscaping and path. The project has been divided into two parts:

• Elizabeth Drive West upgrade, covering 3.6 km from The Northern Road to near where the M12 will cross Elizabeth Drive at Badgerys Creek, and
• Elizabeth Drive East upgrade - approximately 7.8 km from the intersection of the future M12 and Elizabeth Drive at Badgerys Creek to 600 metres east of Duff Road at Cecil Park.

Mamre Road upgrade Stage 2 - Erskine Park Road, Erskine Park and Kerrs Road, Kemps Creek will deliver a six-lane dual carriageway to Mamre Road in Penrith City Council, Sydney.

Works as part of Stage Two include:

• upgrades to two existing intersections (James Erskine Drive and Bakers Lane)
• upgrades to two future intersections (Abbotts Road and Aspect Industrial Estate)
• road widening: six lanes (three in each direction)
• a shared user path on eastern side of the carriageway, and 
• a footpath on the western side of the carriageway.

Transport for NSW has announced that Mamre Road Stage 2 and Elizabeth Drive Upgrade between Badgery's Creek Road and Devonshire Road are to be delivered as a combined package of works (EDU/MRS2). Details on the remaining section of the Elizabeth Drive Upgrade east of Devonshire Road are yet to be announced.

The Elizabeth Drive package of work includes:

• road widening from two to four lanes
• new stormwater infrastructure
• construction of two twin bridges, and
• provision of active transport infrastructure.

The Byford Rail Extension is an eight-kilometre extension of the Armadale line from Armadale Station to Byford and includes:

• a new ground-level Byford Station with approximately 400 parking bays
• elevated rail through Armadale, with a new elevated Armadale Station, and
• removal of eight level crossings at Armadale Road, Forrest Road, Church Avenue, Seventh Road, Byron Road, Eleventh Road, Thomas Road and Larsen Road.

The CopperString 2032 project, formerly known as CopperString 2.0, initially involves building 840 kilometres of new electricity transmission line from south of Townsville in the Burdekin region to Mount Isa that will connect Queensland’s North West Minerals Province (NWMP) to the National Electricity Market.

The CopperString project comprises the delivery of:

• 330-kilovolt (kV) transmission line from just south of Townsville to Hughenden (Eastern Link)
• 330-kV transmission line from Hughenden to Cloncurry
• 220-kV transmission line from Cloncurry to Mount Isa
• up to six new substation sites, and
• workforce accommodation and facilities in strategic locations along the corridor.

The project is being led by the Queensland Investment Corporation (QIC). Powerlink was previously delivering the project prior to QIC's review in October 2025.

The Bundey BESS and Solar Project is a proposed 900-megawatt (MW) solar farm and 1.2-gigawatt / three-gigawatt hour battery, located northeast of Robertstown, South Australia.

The project is proposed by Genaspi Energy Group.
