The Ultimate Australian Squid Jig Size Guide

When choosing a squid jig in Australia, remember this golden rule: size controls how well you stay in the strike zone.

While the profile of the lure matters, jig size is what really dictates your casting distance, sink rate, depth control and how naturally the presentation sits over reef, weed and pier structure.

If you want the broadest buying overview first, go back to the main guide on the best squid jig in Australia.

The full Australian size range, from finesse to heavy-duty

In Australian eging, squid jigs can realistically range from 1.8 right through to 4.0. The key is understanding the personality of each size, not just the number on the packet.

1. The finesse sizes: 1.8 and 2.0

Sizes 1.8 and 2.0 are usually associated with lighter, more finesse-driven fishing styles. They make more sense in warmer-water regions, ultra-clear water, or when the squid are unusually cautious and you want the presentation to look as subtle as possible.

Best uses for 1.8 and 2.0

• very shallow reef
• crystal-clear water
• ultra-finesse presentations
• spooky or highly pressured squid
• lighter tackle sessions

The Victorian context

Around Melbourne and much of Victoria, these are more niche than mainstream. They can still be useful around places such as Mornington Pier Squid Fishing or Rye Pier Squid Fishing on calmer days, especially when targeting smaller squid or fishing especially lightly.

The downside

They struggle once the breeze builds. If the wind gets up, you lose line tension, lose contact and stop fishing the jig properly.

2. The slow sink option: 2.5

A 2.5 is the go-to when you want a slower, lighter presentation that hangs in the water longer.

Best uses for 2.5

• shallow reef
• thick weed beds
• calmer conditions
• cautious squid
• situations where the jig needs to stay above structure longer

The big advantage is hang time. On shallow ground, a 2.5 often stays above the structure longer and looks less forced, which gives tracking squid more time to commit before the jig gets too low.

3. The all-rounder: 3.0

The 3.0 is still the gold standard for most Australian anglers. If you are starting out, this is the size to tie on first.

Why 3.0 stays king for most anglers

• strong balance of castability and sink-rate control
• useful across many piers and breakwalls
• good on mixed reef and weed bottom
• handles average Australian conditions better than almost anything else

For many sessions, 3.0 is the size that does the least wrong. That is why it keeps turning up as the safest starting recommendation.

4. The power presentation: 3.5

Step up to a 3.5 when you need more presence and, more importantly, more authority over the elements.

Best uses for 3.5

• deeper water
• stronger current
• more wind
• longer casts
• situations where the jig must get down efficiently

In open water, deeper channels or harder Victorian conditions, a 3.5 often gives you better contact with the bottom half of the water column where the better squid often sit.

The underestimated option: 3.5 slow sinking

One size that does not get talked about enough is the 3.5 slow-sinking jig.

A lot of anglers look at a 3.5 and assume it must be too aggressive for shallower water, but that is exactly why the slow-sinking versions are underrated. They give you the bigger profile of a 3.5 without forcing the jig to rush straight through the zone.

Why that matters:

• it usually casts further than smaller finesse sizes
• it can stay in the strike zone longer than a standard or fast-sinking 3.5
• it is often less prone to fouling in shallow reef and broken weed than anglers expect
• the bigger silhouette makes it easier for squid to find and commit to

In practical Australian fishing, that makes a 3.5 slow sink a very smart crossover option for shallow reef, cleaner weed edges and low-light sessions where you still want reach and presence without overcooking the sink.

5. The heavyweight: 4.0

A 4.0 is not an everyday size for most anglers, but it absolutely has a place in hard-running water and heavier coastal conditions.

It tends to make the most sense in places and situations where current, depth and exposure are all working against you. That is one reason larger sizes feel more relevant in parts of WA and VIC, where wind, surge or harder tidal movement can make lighter jigs feel underdone very quickly.

Best uses for 4.0

• deep-water eging
• stronger tidal movement
• very windy sessions
• targeting larger Southern Calamari in demanding conditions
• situations where a 3.5 still struggles to get down and stay there

It is really a sink-rate guide in disguise

This is the part beginners often miss. A size guide is really a sink-rate guide in disguise.

The goal is not to choose the “biggest” or “smallest” jig. The goal is to choose the size that keeps the lure fishing properly in the water you are standing in.

Current strength and what it means for jig size

Light or almost no current

Fish smaller and slower. This is where 1.8, 2.0 and 2.5 can all make sense, especially if the water is shallow or the squid are tracking carefully.

Moderate current

This is where 3.0 becomes extremely hard to beat. It gives you the most natural darting action while still keeping proper control of the sink.

Strong current or heavy wind

This is where 3.5 and 4.0 come into play. There is no point choosing a subtle presentation if the jig never gets into the strike zone in the first place.

Recommendations by real fishing scenario

Shallow reef

Start with a 2.5. The goal is to hover just above the reef without constant fouling.

Pier fishing

Start with a 3.0. It gives you the best overall mix of casting distance, sink control and general-purpose fishability.

Deep water or high flow

Start with a 3.5, and do not be afraid to step into a 4.0 if the current is still beating you.

Finicky squid

If squid are following but not grabbing, downsize. A 1.8, 2.0 or 2.5 can make the whole presentation look less aggressive and stay in front of them longer.

The smart starter kit

If you are building a tackle box from scratch, do not waste money on random duplicates. A cleaner starter spread looks like this:

1. one 3.0 as your main workhorse
2. one 2.5 for shallow water or fussier squid
3. one 3.5 for deep water or windy days
4. if you fish in harder Victorian or Western Australian current, add one 4.0

That covers a lot more real fishing situations than a tackle wallet full of similar midsized jigs with no clear purpose.

Final word

The best squid jig size in Australia depends on depth, current and how naturally you can keep the lure in the strike zone.

2.5 shines in the shallows, 3.0 is still the all-round benchmark, 3.5 earns its place once current and wind build, and 4.0 exists for the heavy-duty end of the job.
