If you’ve ever walked the planks of the Wallaroo Jetty, you know the “ink stain” test. You look down, count the black splashes on the timber, and you know exactly where the action is. But knowing where the squid are is only half the battle; the real secret lies in what you’re dangling over the side.
The Spencer Gulf is home to some of the world’s most aggressive and delicious Southern Calamari. However, with the clear water and high vantage point of a jetty like Wallaroo, these cephalopods can be notoriously finicky. After years of “slow traveling” the Yorke Peninsula and testing everything from bargain-bin jags to high-end Japanese “Egi,” we’ve narrowed it down to the absolute best.
Here is our deep dive into the 7 best squid jigs for the Wallaroo Jetty, focusing on the industry leaders: Yamashita and Yo-Zuri.
Understanding Egi Sizes and Colors for the YP
Before we get into the specific jigs, let’s talk about the “Wallaroo Specs.”
- Size (Egi): For the Wallaroo Jetty, Size 3.0 is your “all-rounder.” It sinks at a rate that allows you to work the weed lines at the 400m mark without snagging constantly. In the deeper water at the commercial end, or during the winter “monster squid” run, step up to a Size 3.5.
- The Foil (The Under-layer): * Gold/Rainbow: Best for bright, sunny days in the Spencer Gulf.
- Red/Purple: The go-to for low light or overcast conditions.
- Keimura (UV): A game-changer for clear water. It reacts to UV light and looks “alive” to a squid’s eye.
1. Yamashita Egi Oh Live – 005 Muramura Cherry (UV)
The Yamashita Egi Oh Live series is arguably the most famous squid jig in Australia, and the “Muramura Cherry” is the king of Wallaroo.
- Why it works: This jig features a Keimura (UV) body with a translucent pink back. In the crystal-clear waters of the Yorke Peninsula, the UV body glows with a subtle blue hue that squid find irresistible.
- The Tech: It uses Yamashita’s patented “Warm Jacket” cloth, which actually converts light into heat, mimicking the body temperature of a live baitfish.
- Best For: Clear water and bright sunny days.
2. Yo-Zuri Aurie-Q Cloth – Blue/Silver Foil
Yo-Zuri has a reputation for being “bulletproof” against the sharp beaks of calamari. The Yo-Zuri Aurie-Q in a natural Blue/Silver is a “match the hatch” masterpiece.
- Why it works: This jig mimics the local Blue Pilchards or Tommies that frequent the jetty piles. When the squid are being timid and ignoring the bright “loud” colors, switching to this natural silhouette often triggers a strike.
- The Tech: It features a sinker designed to prevent snags on the jetty’s cross-beams and a very realistic “eye” that serves as a strike point.
- Best For: When the water is “gin clear” and the squid are being fussy.
3. Yamashita Egi Oh K – 006 Military Eggplant
The Egi Oh K series is designed for “tough” conditions. If the Spencer Gulf is a bit choppy or there’s a strong tide running under the jetty, the “K” is your best friend.
- Why it works: It features a “hydro fin” at the back that stabilizes the jig, preventing it from tumbling in the current. The “Military Eggplant” (a dark purple) creates a strong silhouette against the sky—perfect for the squid looking up from the weed beds.
- The Tech: The 490nm Glow technology—the exact wavelength of light most visible to a squid’s eye.
- Best For: Overcast days and choppy water.
4. Yo-Zuri Ultra Bait – Luminous Pink
Sometimes, simple is better. The Yo-Zuri Ultra Bait is a classic “Oita” style jig that has been catching squid in South Australia for decades.
- Why it works: It is highly buoyant and has a very traditional darting action. The “Luminous Pink” is a high-vis powerhouse. If you are fishing the 540m public section where the water is a bit shallower, this jig’s hover-time is excellent.
- The Tech: Internal holographic prism finish that reflects light in every direction.
- Best For: Dawn, dusk, and beginners.
5. Yamashita Egi Oh Live – 036 Japanese Horse Mackerel (490 Glow)
Squid love Yakka (Horse Mackerel). The Yamashita 490 Glow Natural series combines a realistic baitfish print with that scientific glow.
- Why it works: It looks like a real fish during the day, but as the sun sets over the gulf, the 490nm glow patterns start to pulse. It’s the ultimate “transition” jig for those late afternoon sessions at Wallaroo.
- The Tech: Slim nose design that allows the jig to “dart” with very little rod effort—perfect for those long sessions where you don’t want to tire out your wrist.
- Best For: Late afternoon into sunset.
6. Yo-Zuri Mag Q Tungsten – Orange Glow
If you want to reach the deep water at the very end of the 800m mark, you need weight and distance. The Yo-Zuri Mag Q is the long-distance champion.
- Why it works: It features a magnetic weight transfer system. When you cast, the weight shifts to the tail for maximum distance; when it hits the water, it shifts back for a perfect horizontal sink.
- The Tech: Tungsten weights allow for a smaller profile with a faster sink rate, cutting through the wind.
- Best For: Reaching the deep-water “big ones” at the commercial end of the jetty.
7. Yamashita Egi Oh Live Neon Bright – 062 Red Body
The “Neon Bright” is the latest innovation in Egi. While traditional UV (Keimura) is blue, the Neon Bright comes in Red, Green, and Blue.
- Why it works: The Red Body is specifically designed for “prime time”—sunset and sunrise. It glows with a red UV frequency that stands out even when the light is fading.
- The Tech: Neon Bright technology is 3x more reflective than standard UV, making it visible even in slightly murky water after a storm.
- Best For: Sunrise sessions before the grain ships start their day.
Pro Tip: The Wallaroo “Drop”
Because the Wallaroo Jetty is so high (approx. 8 meters), your jig’s “sink angle” is affected by your line height. To get a natural presentation, cast out as far as you can and keep your rod tip low. Once the jig hits the weed line, give it two sharp “rips” (jags) and then let it sit on a semi-slack line. Most of your hits will happen on the “drop.”
