Gas comparison South Australia: how the market works
National Energy Customer Framework
South Australia has adopted the National Energy Customer Framework, so AER retail rules apply. The AER does not set retail gas prices.
ESCOSA gas distribution regulation
ESCOSA is determining the 2026-2031 regulatory framework for AGN South Australian gas distribution services from 1 July 2026.
South Australian gas distribution networks
South Australia's mains gas network is concentrated around Adelaide and selected regional centres. Off-network households should compare LPG supply as part of the decision.
Australian Gas Networks South Australia
Adelaide and surrounds, Mount Gambier, Whyalla, Port Pirie, Barossa Valley, Murray Bridge and Berri
AGN owns South Australia's main gas distribution network. ESCOSA is making a 2026-2031 regulatory determination for AGN distribution services.
APA-operated distribution services
Operations and maintenance for AGN distribution assets
The AEMC gas pipeline register notes AGN owns the SA distribution network and outsources network operation to APA Group.
Regional LPG supply
Regional homes and properties outside natural gas mains
LPG bottles can matter for off-network South Australian households. SACEDO includes a 45 kg LPG cylinder discount through Origin for eligible customers.
Embedded and bulk gas arrangements
Apartments, parks, retirement villages and private networks
Some customers pay through an on-supply or embedded arrangement, which can affect switching options and concession payment methods.
Current SA gas reference prices and regulated rates

Use your postcode, annual MJ usage, daily supply charge, usage blocks, concession status and whether you use mains natural gas or LPG. South Australia has no retail gas default offer, so compare estimated annual costs from retailer plan documents.
Does South Australia have a regulated gas reference price?
No. South Australia has an electricity Default Market Offer, but there is no equivalent regulated retail gas reference price. Gas network regulation and retail market rules sit underneath retailer plan pricing.
