The square coconut biscuit behind every South African fridge tart does not exist in Australia. Here is the swap that works, the ones that sort of work, and where to buy the real thing.
Somewhere between the condensed milk and the caramel, every South African baker in Australia hits the same wall: the recipe says Tennis biscuits, and the biscuit aisle says no. There is no Australian version, no local licensing deal, and no biscuit called anything like it. The good news is that the working substitute costs a few dollars and sits in every Coles and Woolworths in the country.
In short, the best tennis biscuits substitute Australia stocks is Arnott’s Nice, and the rest of this guide covers how to use it, where it falls short, and where to find the real thing.

What makes a Tennis biscuit a Tennis biscuit
Tennis biscuits are square, thin, crisp and coconut flavoured, and that combination is the whole point. They crush into an even, buttery base for fridge tarts, hold a layer without going soggy too fast, and bring a coconut note that plain biscuits cannot. Any substitute has to tick those boxes: thin, crisp, coconut. A biscuit that is merely sweet will hold a tart together, but it will not taste like home.
The swap that works: Arnott’s Nice biscuits
Arnott’s Nice biscuits are the substitute we use and the one the expat consensus has settled on. They have the same coconut flavour and a similar crisp texture, and Australian bakers already use them as the base for layered fridge desserts, including local versions of peppermint crisp tart. If a recipe calls for a Tennis biscuit base, swap gram for gram and carry on. Nothing else about the recipe needs to change.
It helps that the rest of the tart is solved on this side of the ocean too. Peppermint Crisp is made in Australia and sells in the regular confectionery aisle, and Nestlé Top ‘n’ Fill covers the Caramel Treat layer. The full list of those swaps lives in our complete substitutes guide.
A fair warning about the shape and the flavour
Nice biscuits are not a perfect twin. Tennis biscuits are square; Nice biscuits are thin and rectangular with notched edges, and they are lightly dusted with sugar crystals. Wikipedia’s entry on the Nice biscuit also says they come plain or coconut flavoured, so read the packet and pick the coconut one. For a crushed fridge tart base the shape does not matter at all, because you are about to smash them. For a tart where you lay whole biscuits in layers, you may need to trim or patch the edges.
How to use Nice biscuits as the base
Arnott’s own classic Nice cheesecake shows how well the biscuit crushes. The recipe blitzes a 250 g packet of Nice in a food processor until fine, mixes it with melted butter, presses it up the sides and across the base of a 22 cm springform tin, and chills it before the filling goes in. That is a cheesecake, not a fridge tart, so follow your own recipe for amounts. But the lesson carries over: crush the biscuits fine, press them down firmly, and chill the base so it sets before you add the filling.
For peppermint crisp tart, the other half of the job is the chocolate. Nestlé’s Peppermint Crisp bar is made in Australia and sold at Woolworths, with a crunchy peppermint cracknel centre, and it crushes straight over the top. For the caramel layer, our guide to the Caramel Treat substitute covers what to use.
The second-string options
If your recipe leans harder on structure than on coconut, a plain Marie-style biscuit will do the mechanical job, and expat forums will offer you everything from digestives to ginger nuts in a pinch. They all work as engineering. None of them taste right. Treat them as what they are: a way to finish a tart on a Sunday when the shops are shut, not a substitute you plan around.
Some South African shops in Australia also stock coconut biscuits sold specifically as Tennis alternatives, including imported all-day style coconut biscuits. If you are already ordering biltong, adding a packet to the box is no extra effort.
Where to buy real Tennis biscuits in Australia
The genuine article crosses the ocean in the import boxes of South African shops. Most of the walk-in shops in our state-by-state directory carry them when stock allows, and the online shops that ship Australia-wide list them regularly. Stock moves fast around holidays, so if you see them, buy two boxes. You already know why. If you are stocking up on other South African pantry items at the same time, our guide to the Mrs Balls chutney substitute is worth a read.
One last tip from the kitchen: buy your biscuits and your Peppermint Crisp in the same shop run, and make the base the day before. A fridge tart needs hours to set, and a chilled crumb base that has had a night in the fridge cuts far more cleanly. If the real Tennis biscuits turn up later, keep them for the next tart and treat the Nice version as your everyday backup.
Frequently asked questions
What are Tennis biscuits called in Australia?
Nothing. They do not exist here under any name. The closest local biscuit is Arnott’s Nice, a thin, crisp coconut biscuit that swaps into Tennis biscuit recipes gram for gram.
Can I use Nice biscuits for peppermint crisp tart?
Yes. Australian bakers already build peppermint crisp tart on a Nice biscuit base, and the coconut flavour keeps the tart close to the original. Peppermint Crisp itself is made in Australia, so every layer of the tart is solved locally.
Do any Australian shops sell real Tennis biscuits?
South African shops import them. Check the walk-in shops in our state-by-state directory or the online shops that ship Australia-wide, and ring ahead if you are driving far, because import stock comes and goes.
Are Nice biscuits the same shape as Tennis biscuits?
No. Tennis biscuits are square, while Nice biscuits are thin and rectangular with notched edges. For a crushed base the shape does not matter. For a layered tart, you may need to trim them.
Should I buy plain or coconut Nice biscuits?
Read the packet and choose the coconut one. Nice biscuits can be plain or coconut flavoured, and the coconut note is what keeps a fridge tart close to the original.
How many biscuits do I need for a fridge tart base?
Swap gram for gram with the weight in your recipe. A standard Nice packet is 250 g, so weigh what the recipe asks for and buy enough packets to cover it.
