If you're setting up an ASIC miner at home in Australia, your state isn't just a postcode — it's one of the most important variables in your profitability calculation. Electricity rates vary meaningfully between WA, QLD, and NSW, and a difference of even a few cents per kilowatt-hour compounds dramatically when a miner runs 24 hours a day, 365 days a year.
This guide breaks down current residential electricity rates in each state, what they cost for typical ASIC hardware, and which strategies Australian home miners use to reduce their effective rate.
Why Electricity Rate Matters More Than Hashrate
The profitability of any ASIC miner comes down to a simple equation: mining revenue minus electricity cost. Revenue is determined by your hardware's hashrate, the current Bitcoin price, and network difficulty — none of which you control. Electricity cost is determined by your hardware's power draw and your rate per kWh, which you do have some influence over.
In 2026, analysis of global mining economics places the break-even electricity rate for modern sub-15 J/TH ASICs at roughly $0.08–$0.10/kWh for meaningful profitability. Australia's residential rates sit well above that in every state. This doesn't mean home mining is impossible — but it does mean the specific rate you pay, and any strategies that bring it down, matter enormously.

Western Australia: Regulated, Predictable, and Mid-Range
Western Australia operates an electricity market unlike the rest of the country. Rather than a competitive retail market, WA residential customers on the main SWIS grid are supplied by Synergy, a government-owned utility, with prices set annually by the State Government rather than the Australian Energy Regulator.
As of 1 July 2025, the Synergy Home Plan (A1) — the standard residential flat rate — is set at 32.37 cents per kWh, with a daily supply charge of 116.05 cents per day. This rate applies at any time of day, making it straightforward to calculate ongoing mining costs.
What this means for ASIC miners in WA
At 32.37c/kWh, running a 3,500W commercial ASIC continuously costs approximately $823/month in electricity. A 2,643W machine like the Antminer S21 costs around $622/month. A 140W low-power miner like the Canaan Avalon Nano 3S costs approximately $33/month.
The advantage of WA's regulated model is predictability. Rate changes happen once a year on 1 July, announced in advance by the State Government. WA miners can plan their economics with a stable, known rate rather than navigating a competitive retail market where plans and rates shift frequently.
The downside is limited flexibility — there is no competitive market to shop for a better deal. Synergy's time-of-use Midday Saver Tariff offers lower off-peak rates overnight, which can be valuable for miners who can schedule operations — but this requires a smart meter installation.
WA: Key numbers at a glance
- Standard flat rate: 32.37c/kWh (Synergy A1, from 1 July 2025)
- Market structure: Regulated monopoly — no retailer competition
- Time-of-use option: Midday Saver Tariff (requires smart meter)
- Rate certainty: High — one government-set change per year
Queensland: The Most Competitive Environment for Home Miners
Queensland has a split electricity market. South East Queensland (SEQ) — covering Brisbane, Gold Coast, Sunshine Coast, and surrounds, home to roughly two-thirds of the state's population — has a fully competitive retail market served by the Energex distribution network. Retailers compete for customers, and market offers can be meaningfully cheaper than the default reference price.
Regional and rural Queensland is served by Ergon Energy on a regulated tariff, similar in structure to WA's Synergy model.
In SEQ in 2026, residential usage rates on competitive market offers range from approximately 28 to 32 cents per kWh, with the cheapest available plans coming in at the lower end of that range. The AER's Default Market Offer (the reference price cap) for a typical SEQ household sits at around $2,143 per year based on 4,600 kWh annual usage.
Importantly, QLD electricity prices are expected to fall further from 1 July 2026. Ergon Energy has signalled draft price reductions of approximately $200/year for a typical regional household, driven by lower wholesale electricity costs — and SEQ competitive retailers are likely to follow.
What this means for ASIC miners in QLD
At 28–30c/kWh on a competitive market offer, the economics improve meaningfully versus the national average. Running a 2,643W Antminer S21 continuously costs approximately $563–$604/month at these rates — roughly $20–$60/month less than in WA, and considerably less than NSW.
The competitive retail market is the key advantage for QLD miners. Shopping plans actively, locking in a low market offer, and taking advantage of any pay-on-time or direct debit discounts can reduce the effective rate below the headline figure. Retailers including Red Energy, OVO Energy, and GloBird have offered some of the most competitive SEQ rates in 2026.
QLD also has relatively favourable solar conditions, and miners who can offset daytime draw with a solar system reduce their effective rate further — though any miner running overnight will be drawing from the grid regardless.
QLD: Key numbers at a glance
- SEQ market offer rate: ~28–32c/kWh (competitive, varies by retailer)
- Regional QLD (Ergon): regulated flat rate, similar to WA pricing
- Market structure: Competitive in SEQ — shop for the best deal
- July 2026 outlook: Prices expected to decrease for regional customers
- Rate certainty: Moderate in SEQ — plans change, shopping required
New South Wales: Highest Rates, Largest Market
NSW has the largest electricity market in Australia by customer volume, with full retail competition across the state served by Ausgrid (Sydney and surrounds), Endeavour Energy (Western Sydney and regional), and Essential Energy (regional NSW). The AER's Default Market Offer sets the reference price cap, but competitive market offers are available from a wide range of retailers.
In 2026, typical residential usage rates in NSW average approximately 33–35 cents per kWh on single-rate tariffs, with the Ausgrid network in Sydney often cited at around 34c/kWh. NSW consistently comes in as one of the more expensive states for residential electricity in Australia.
What this means for ASIC miners in NSW
At 34c/kWh, running a 2,643W Antminer S21 costs approximately $653/month in electricity — around $50/month more than an equivalent setup in QLD on a competitive plan, and roughly $30/month more than WA. Over a year, that's $360–$600 more in electricity costs for the same hardware doing the same work.
Like QLD, NSW has a competitive retail market, and the cheapest market offers are meaningfully below the default rate. Time-of-use tariffs are also widely available — overnight off-peak rates in NSW can be considerably lower than the flat rate, which creates a genuine opportunity for miners willing to configure their hardware to run predominantly overnight.
NSW also has strong solar penetration, and miners who can generate and self-consume solar power during daytime operation can bring their effective rate down. The catch, again, is that mining is a 24/7 operation — overnight hours will always draw from the grid.
NSW: Key numbers at a glance
- Typical flat rate: ~33–35c/kWh (varies by network and retailer)
- Market structure: Fully competitive — multiple retailers and networks
- Time-of-use options: Widely available, off-peak rates can be significantly lower
- Rate certainty: Lower — competitive market means frequent plan changes
State-by-State Comparison: Monthly Electricity Cost by Miner
The table below shows estimated monthly electricity costs for three popular miners at the indicative 2026 residential rates for each state. These are electricity cost only — not inclusive of daily supply charges.
| Miner | Power Draw | WA (32.37c) | QLD (29c) | NSW (34c) |
|---|---|---|---|---|
| Avalon Nano 3S | 140W | ~$33/mo | ~$30/mo | ~$35/mo |
| Antminer S19K Pro | 2,760W | ~$648/mo | ~$580/mo | ~$680/mo |
| Antminer S21 | 2,643W | ~$621/mo | ~$556/mo | ~$651/mo |
| Antminer S21 Pro | 3,510W | ~$825/mo | ~$739/mo | ~$865/mo |
Figures assume continuous 24/7 operation at the stated power draw and the mid-point residential rate for each state. Actual costs will vary by plan, network, and usage profile.
How to Reduce Your Effective Electricity Rate as a Miner
Whatever state you're in, the headline residential rate isn't necessarily the rate you have to pay. Here are the strategies Australian home miners use to reduce their effective cost per kWh:
Shop competitive market offers (QLD SEQ and NSW)
In competitive markets, the gap between the default reference price and the cheapest available market offer can be $300–$500 per year on a typical household bill. For a miner adding significant load on top of household usage, the benefit of a low market offer is amplified. Review plans annually — rates change, and loyalty rarely pays in competitive electricity markets.
Switch to a time-of-use tariff and mine overnight
Time-of-use (TOU) tariffs charge lower rates during off-peak periods — typically overnight from around 10pm to 7am in most networks. Off-peak rates can be 30–50% lower than the peak flat rate in some plans. An ASIC miner configured to run primarily during off-peak hours can significantly reduce its effective per-kWh cost, though most miners won't want to switch off during peak hours entirely.
Install solar and self-consume during the day
A solar system that offsets daytime electricity draw effectively reduces the cost of that power to near zero. For miners running during daylight hours, self-consumed solar is the most impactful rate reduction available in any state. In WA, Perth's high solar irradiance makes this particularly effective. Note that feed-in tariffs for exported solar are low across all states in 2026 (2–10c/kWh depending on the scheme), so maximising self-consumption rather than exporting is the priority.
Negotiate a business tariff if your consumption qualifies
High-consumption operations — particularly those with multiple commercial miners — may qualify for business or large-user electricity tariffs, which can be structured differently to residential plans and may offer better per-kWh economics at scale. This is worth investigating if your mining operation has grown beyond a single machine.
The Verdict: Which State Is Best for Home Miners?
On headline residential rates alone, Queensland (SEQ) offers the most favourable conditions for home miners in 2026 — competitive market offers can bring rates to 28–30c/kWh, below both WA's regulated 32.37c and NSW's typical 33–35c. The competitive retail environment also gives QLD miners ongoing ability to shop for better deals as the market evolves.
WA's regulated model sits in the middle on rate but wins on predictability — miners can plan 12 months ahead knowing the rate won't shift unexpectedly. It's also worth noting that WA's government has historically used the regulated tariff as a cost-of-living lever, and future rate movements depend on State Government policy as much as wholesale market dynamics.
NSW has the least favourable headline rates but the most developed time-of-use infrastructure, meaning miners who can actively optimise their operating hours have real tools to bring their effective rate down below the flat-rate figures above.
In all three states, the honest conclusion is the same: commercial ASIC miners are challenging to run profitably at residential rates in 2026. The most viable approach for Australian home miners on standard residential tariffs is either low-power hardware (where the absolute electricity cost is small regardless of rate) or a deliberate strategy to reduce effective rate through TOU tariffs, solar, or plan optimisation.
