Who supplies electricity in Newcastle?
Ausgrid generally supplies Newcastle (Sydney, Central Coast, Hunter). Poles and wires are owned by the distributor and are the same whichever retailer bills you, so switching retailer never changes the physical connection. Your bill confirms the network at your address.
| Network | Area | Reference price |
|---|---|---|
| Ausgrid | Sydney, Central Coast, Hunter | $1,899 at 3,900 kWh (48.7 c/kWh all-in) |

How good is the internet in Newcastle? What the NBN looks like
Across Newcastle, the NBN dataset classifies 179,525 premises. Which technology you are on matters more than which provider you pick, because the technology limits your speed tiers.
- Fibre to the premises: 40.7%
- Fibre to the curb: 2.2%
- Fibre to the building: 0.9%
- Fibre to the node: 56.0%
41% of classified premises are on fibre to the premises and 56% on fibre to the node. Check your own address before choosing a speed tier.

Moving to Newcastle? Getting power and internet connected
Tell your chosen retailer your move-in date a few business days ahead and they arrange the connection with the network. Ask which NBN technology your address has before you pick an internet plan: fibre to the node or fibre to the curb homes can need an installer visit, so book earlier. New builds should confirm with the builder that the meter and NBN connection are ready.
Our take on Newcastle
With Ausgrid as the network, the price differences you can act on come from the retailer, not the poles and wires. A 15% discount on the $1,899 reference price saves about $285 a year, so check the supply charge and any conditions, not only the percentage. 41% of Newcastle premises are on fibre to the premises, so on internet the choice is mostly about price and contract terms.
