Melbourne Coles vs Woolworths Prices + protein density 2026 update

15 Best Protein Bars Melbourne 2026: Every Coles & Woolworths Option Tested & Ranked

Last store check: May 11, 2026 | Coles Melbourne CBD & Woolworths South Yarra | Prices can change weekly (we update this page when specials change).

If you’re trying to find a protein bar in Melbourne that’s actually worth the money, the fastest shortcut is simple: compare protein per 100g (density) and cost per gram of protein (value), then sanity-check sugar. This guide does exactly that for Coles and Woolworths.

Quick gut tip: If protein bars bloat you, it’s often the sugar alcohols and fibre blend. A small add-on some people find easier is 1 tsp moringa powder with water after eating.

🏆 How We Score Protein Bars (Melbourne Method)

We rate each bar out of 10.0 using a weighted score based on label data and local availability. It’s designed to be practical for shopping at Coles/Woolworths in Melbourne.

1) Protein Density (40%)

What it is: protein per 100g (standardised).

Guide: 45g+/100g = excellent • 25–35g/100g = average • <20g/100g = low.

2) Value (25%)

What it is: cost per gram of protein (lower is better).

Guide: <$0.10/g = excellent • ~$0.15/g = average • >$0.25/g = poor.

3) Sugar (15%)

What it is: sugar per 100g (lower is better).

Guide: <2g/100g = excellent • 5–10g/100g = average • >15g/100g = high.

4) Digestibility (10%)

What it is: a practical penalty for heavy sugar alcohols / very "busy" ingredient decks.

Extra test: "moringa compatibility" (can you take 1 tsp after without feeling worse).

5) Availability (10%)

What it is: how easy it is to buy in Melbourne.

Guide: Coles + Woolworths = 10/10 • specialty only = 5/10 • online only = 3/10.
