Gallagher and Thunderbird are the two dominant electric fence energiser brands in Australian agricultural retail. Both make quality products but they have different strengths, and the right choice depends on your specific situation.

Gallagher

Gallagher is the market leader globally and in Australia, with the widest product range from small hobby farm units through to high-output mains and solar energisers for large commercial operations. Gallagher's M-Series (mains) and S-Series (solar) are their flagship ranges.

Strengths: Industry-leading output consistency, largest dealer and spare parts network in Australia, well-integrated with their own fencing components, excellent warranty support.

Best for: Larger operations, permanent fencing, producers who want the broadest range of accessories and aftermarket support.

Thunderbird

Thunderbird is an Australian-designed brand with a loyal following particularly in Queensland and NSW. Their S-Series solar energisers have an excellent reputation for reliability in harsh Australian conditions.

Strengths: Very competitive pricing, robust build quality suited to Australian conditions, strong solar range, good warranty.

Best for: Budget-conscious buyers, solar-powered remote installations, producers who prioritise value for money.

How to Choose

The most important factors are: fence length (km), number of wires, vegetation contact, and power source. As a general rule, buy 30–40% more capacity than you think you need. Browse our full Electric Fencing range including both brands.
