The Breakdown
Australian Bananas (Hort Innovation) · Banana Gym Pass: Bring a banana, bring a mate
One banana, two gym entries: how a simple swap gets people moving
Australian Bananas' gym pass is back for a third year, and this time it's built for two. Show up with a banana on National Banana Day and you and a mate get free entry to over 900 gyms.
The TL;DR (too long; didn't read)
- For one day (7 October), bringing a banana to a participating gym gets you and a friend free entry.
- More than 900 gyms took part this year, via Thinkerbell and media partner Nova FM.
- The new twist is 'bring a mate': the platform is betting that shared workouts beat solo ones.
01
A prop, not a promo code
The 'currency' here is a banana, something nearly everyone already has in the fruit bowl. That's a much lower barrier than downloading an app or printing a voucher, and it's instantly explainable in one sentence.
02
Why 'bring a mate' changes the pitch
Past years rewarded the individual turning up. This year the reward only really works with two people, which turns a personal habit (going to the gym) into a social one.
Nova FM's breakfast hosts modelled exactly that: one host challenged the other to rack up visits, with a 'mate' pushing them along.
03
A one-day urgency, no result yet
Free entry is only available on National Banana Day itself, which pushes people to act that day rather than 'some day'. It's a clear, bounded offer rather than an open-ended one.
No attendance or sales figures have been published yet, so whether 'bring a mate' actually lifted participation versus solo visits is still an open question.

The theory bit
The academic ideas that explain what's going on, with the full reference for your assignments.
Scarcity & social proof
People value things more when they're limited (scarcity) and look to what others are doing to decide what's worth doing (social proof).
Here: The free entry is good for one day only, which creates urgency, and 'bring a mate' adds a social-proof nudge: you're more likely to go if someone else is counting on you.

Fogg Behaviour Model (B = MAP)
A behaviour happens when Motivation, Ability and a Prompt come together. Making an action easier is often more effective than adding motivation.
Here: The Prompt is National Banana Day, the Ability is as easy as owning a banana, and the Motivation is boosted by having a mate involved. All three line up, which is the model's recipe for getting a behaviour to actually happen.

Your mini task
In 60–120 words: design a one-day, two-person offer for a brand you like, using one simple, everyday object as the 'ticket'. Explain the prompt, why it's easy to act on, and the social element that gets a second person involved.
