Tesla has extended its Next Million Powerwall rebate. Eligible Powerwall 3 installations ordered before 30 June 2026 can attract up to AUD $1,500 per address, paid as a Visa reward card. The extension is designed to offset the reduction in the federal Cheaper Home Batteries Program, which took effect on 1 May 2026.
For Perth households still considering a battery, the effect is that the all-up cost of a Powerwall 3 system stays close to where it was before the federal scheme winds back.
TLDR
- Tesla has extended its Next Million Powerwall rebate to 30 June 2026. Eligible Powerwall 3 orders attract up to AUD $1,500 per address (two-unit install), paid as a Virtual Visa Reward card after installation. It is a reward card, not cash.
- Tesla is bridging the federal Cheaper Home Batteries Program step-down that took effect on 1 May 2026, keeping all-up Powerwall 3 pricing close to where it sat beforehand.
- Three separate government schemes still stack alongside the Tesla Powerwall 3 rebate: battery STCs, the WA Residential Battery Scheme, and the federal Cheaper Home Batteries Program. The Tesla rebate is a manufacturer's offer that sits on top of all three.
- The Tesla rebate has a key date: get your order in by 30 June 2026. Installation can follow any time up to 31 December 2026, so there is no need to rush the install date itself.
- Already own a Powerwall 2? Adding a Powerwall 3 still qualifies.
The ability to stack
with other battery schemes
There are three separate schemes operating in WA right now, and they do not all do the same thing.
1. Small-scale Technology Certificates (STCs): Battery STCs created under the federal Cheaper Home Batteries Program through the Small-scale Renewable Energy Scheme (SRES). From 1 May 2026, the battery STC factor dropped by approximately 19%, and battery STCs are tiered by capacity: full benefit for the first 14 kWh of battery, 60% for 14–28 kWh, and 15% for 28–50 kWh. STC values are subject to market fluctuation.
2. WA Residential Battery Scheme: The state rebate is paid on the battery itself. Administered by Energy Policy WA. Eligibility and amounts are set by the scheme.
3. Federal Cheaper Home Batteries Program: The federal battery rebate, which reduced in value on 1 May 2026. The Tesla rebate extension is explicitly designed by Tesla to soften that reduction.
The Tesla rebate sits on top of all three. It is a manufacturer’s offer, not a government incentive. That means the eligibility checks and the paperwork are different from the government schemes, and the Tesla rebate is paid by Tesla after installation rather than applied at the point of sale.
The timing
Order a Powerwall 3 system between now and 30 June 2026 and you can line up three discounts at once:
• The current battery STC factor
• The WA Residential Battery Scheme
• The Tesla rebate of up to $1,500
