Short answer: A pair of rubber hex dumbbells from PeterMat costs between $19 and $169 depending on the weight, and delivery is free on any order over $75 AUD. Under $75 the flat rate is $9.95, so a single light pair lands at your door for $28.95 to $58.95, while every pair from 10kg upward ships free on its own.
What it costs to buy dumbbells online in Australia
That is the whole pricing structure. There are ten weight steps, 0.5kg to 25kg, all fixed rubber hex pairs, sold direct to your door with no retail stores in between. The tables below give you the delivered figure for each step and the cost per kilogram, so you can see where the value actually sits before you commit.
Delivered price for every pair, 0.5kg to 25kg
Orders are processed within 1-2 business days and estimated transit to metro Australia is 3-5 business days. The delivered total below assumes you order that pair on its own with nothing else in the basket.
| Pair | Price | Delivery | Delivered total |
|---|---|---|---|
| 0.5kg | $19 | $9.95 | $28.95 |
| 1kg | $22 | $9.95 | $31.95 |
| 2kg | $29 | $9.95 | $38.95 |
| 3kg | $35 | $9.95 | $44.95 |
| 4kg | $42 | $9.95 | $51.95 |
| 5kg | $49 | $9.95 | $58.95 |
| 10kg | $79 | Free | $79.00 |
| 15kg | $109 | Free | $109.00 |
| 20kg | $139 | Free | $139.00 |
| 25kg | $169 | Free | $169.00 |
Six of the ten steps sit under $75 alone, so the flat rate applies to them. Add any second item that takes the order past $75 and the $9.95 comes off, which is worked through in detail on free delivery on gym equipment.
Cost per kilogram, and why the heavy pairs read better
Divide each pair price by the weight in the product name and the curve is steep at the light end and flat at the heavy end. A handle, a rubber coating and the machining cost roughly the same whatever weight sits on the ends, so that fixed cost is spread over more kilograms as you go up.
| Pair | Price | Cost per kg (labelled weight) |
|---|---|---|
| 0.5kg | $19 | $38.00 |
| 1kg | $22 | $22.00 |
| 2kg | $29 | $14.50 |
| 3kg | $35 | $11.67 |
| 4kg | $42 | $10.50 |
| 5kg | $49 | $9.80 |
| 10kg | $79 | $7.90 |
| 15kg | $109 | $7.27 |
| 20kg | $139 | $6.95 |
| 25kg | $169 | $6.76 |
The practical read: if you are torn between the 3kg pair at $35 and the 5kg pair at $49, the extra $14 buys you 2kg more and drops your cost per kilogram from $11.67 to $9.80. If you already know you will get stronger, buy the heavier step now instead of replacing a pair you outgrow in two months.
The curve also explains why nobody should buy the 0.5kg pair as a strength purchase. At $38.00 per labelled kilogram it is a rehab and Pilates weight, and it is priced like the small precise thing it is.
Online against a big box run: four things to compare
We are not going to quote another retailer's shelf prices here, because they move weekly and vary by store. Run this checklist on the pair you actually want, then hold it against the delivered totals above.
- Cost per kilogram: work the figure out for the weight you will lift, not the cheapest pair on the shelf. A cheap 2kg pair and an expensive 20kg pair often sit in the same aisle.
- Range depth: count the weight steps actually in stock. PeterMat carries ten, 0.5kg to 25kg, so the next step up is always there when you are ready for it.
- Delivery or your boot: the 20kg and 25kg pairs are awkward to carry across a car park and up a flight of stairs. Ordered online they come to the door, and at $139 and $169 both are over $75, so freight is free.
- What happens after you pay: online you get a tracking number by email once the order ships, after a dispatch window of 1-2 business days. In store you get whatever is on the shelf that afternoon.
One thing genuinely favours the shop floor: you can pick a dumbbell up before you pay for it. If handle thickness or knurling matters to you, that is worth a trip, and it is the main reason to handle one in person before ordering a full set.
What you are actually buying
Every PeterMat dumbbell is a fixed one-piece pair: a solid cast head under a rubber coating, a chrome knurled handle, and six flat faces so the dumbbell stays put instead of rolling off across the floor.
- One-piece build: nothing to unscrew, no collars to lose, no plates to reset between sets.
- Rubber coated heads: quieter on the floor than bare iron and easier on floorboards and tiles.
- Hex heads: they stay where you put them, which matters in a hallway or a small lounge room.
- Priced per pair: the figure on every listing buys two dumbbells, not one.
There are no adjustable dumbbells, barbells, racks, benches or kettlebells in the range. If your plan needs those, you will be buying them somewhere else, and it is better to know that before you fill a basket.
How to choose your first order
Most first orders overthink the weight and underthink the number of pairs. Two pairs covers far more exercises than one, because your legs and back handle roughly double what your shoulders can press overhead.
- Pick the pair you could press overhead for 10 reps with two reps left in the tank. For many beginners that is the 3kg or 5kg pair.
- Add a second pair one or two steps heavier for rows, squats, lunges and deadlifts.
- Check the basket total. Two pairs clears $75 in almost every combination, so you pay for metal rather than freight.
- Add a mat only if you are lifting over floorboards, tiles or a rental floor you cannot afford to mark.
The 5kg pair on its own is $58.95 delivered. Add the 2kg pair at $29 and the order is $78 with free delivery, so the second pair effectively costs $19.05.
When your order arrives
Orders are processed within 1-2 business days, then transit depends on where you are. These are estimates and can stretch in peak periods or when a carrier runs behind.
| Destination | Estimated transit |
|---|---|
| Metro Australia (Sydney, Melbourne, Brisbane) | 3-5 business days |
| Regional Australia | 5-10 business days |
| Remote Australia | 7-14 business days |
| New Zealand (North and South Islands) | 7-14 business days |
A tracking number is emailed once your order ships. The full terms sit on the shipping page, and anything specific to your address or a parcel that has stopped moving can go to [email protected].
Mistakes that cost money when buying dumbbells online
- Ordering one pair at a time: three separate $29 orders pay $29.85 in freight. The same three pairs in one $87 order ship free.
- Buying too light: the 0.5kg and 1kg pairs are rehab and Pilates weights. If the goal is strength, start at 3kg or 5kg and leave room to progress.
- Guessing the grip: handle diameter is the one thing a photo cannot tell you. Hold something similar first if your hands are small or you have wrist trouble.
- Forgetting the floor: a 20kg pair set down hard on tiles is an expensive noise. Budget for a mat if your floor is hard or you are in a rental.
If the weight is still the open question, the dumbbell size guide works through it by exercise and starting strength, and sets against single pairs covers whether to buy two pairs now or one.

$139Frequently Asked Questions
How much does it cost to have dumbbells delivered in Australia?
Delivery is free on any order over $75 AUD, to every Australian state and territory and to New Zealand. Orders under $75 pay a $9.95 flat rate. Every dumbbell pair from 10kg up is over $75 on its own so those ship free, and lighter pairs ship free as soon as the order total clears $75.
Is it cheaper to buy dumbbells online or in a store?
That depends on the store and the week, so compare on the specific pair you want rather than the range as a whole. PeterMat pairs run from $19 for 0.5kg to $169 for 25kg, which is $38.00 down to $6.76 per labelled kilogram, and anything over $75 includes delivery. Hold that delivered figure against the shelf price plus the drive and the carrying.
What dumbbell weights can I buy online from PeterMat?
Ten fixed rubber hex pairs: 0.5kg, 1kg, 2kg, 3kg, 4kg, 5kg, 10kg, 15kg, 20kg and 25kg. Every price shown buys the pair rather than a single dumbbell. There are no adjustable dumbbells, barbells or kettlebells in the range.
How long do dumbbells take to arrive?
Orders are processed within 1-2 business days. Estimated transit after that is 3-5 business days to metro Australia, 5-10 business days regional, 7-14 business days remote, and 7-14 business days to New Zealand. These are estimates and may vary in peak periods or with carrier delays.
Which dumbbell pair is the best value per kilogram?
The 25kg pair at $169 works out at $6.76 per labelled kilogram, the lowest in the range, with the 20kg pair next at $6.95. Light pairs cost far more per kilogram because the handle, coating and machining cost about the same regardless of the weight on the ends. Buy for the weight you will actually lift, then use cost per kilogram to break a tie.
Do I need two pairs of dumbbells to start?
Two pairs covers more exercises than one, because most people can row and squat with roughly double what they press overhead. A common starting order is one light pair for pressing and one a step or two heavier for lower body and back work. Two pairs also clears $75 in almost every combination, so delivery is free.
Can I buy dumbbells online and have them sent to New Zealand?
Yes, to both the North and South Islands, on the same rules: free over $75 AUD and $9.95 under it. Estimated transit is 7-14 business days after a dispatch window of 1-2 business days. A tracking number is emailed once the order ships.
