Why Scrap Metal Prices in Melbourne Change From Week to Week

Someone sells a load of copper on a Tuesday and gets a decent rate. They come back the following week with the same sort of load and get a different number. Cue the suspicious look. "Why's it dropped? Did you change something?"

Nothing sneaky is going on. Scrap metal prices genuinely move, sometimes by a little and sometimes by a lot, and the reasons are mostly well outside any yard's control. I'd rather you understand what's behind the number than just take it on trust, so here's how it works.

Scrap is priced off the world market

The first thing to know is that scrap metal isn't priced locally in a vacuum. Copper and aluminium are traded around the world every day, and the global price is the starting point for everything else. What a yard pays you is tied to that benchmark, then adjusted for the grade of your metal, the cost of processing it, and the cost of getting it where it needs to go.

So when the world price moves, scrap prices in Melbourne follow, usually within days. Copper is a good example. It hit a record high in January 2026 and has stayed well above where it was a year earlier. Prices don't climb in a straight line, though. They bounce around that level, up one week and down the next, and scrap rates bounce with them.

The Australian dollar plays a bigger part than people think

Here's one that catches people out. Much of the scrap collected in Australia ends up overseas, sold to processors and smelters in other countries, and those sales are priced in US dollars.

That means the exchange rate matters. If the Australian dollar weakens against the US dollar, a yard gets more Aussie dollars for the same shipment, and that can lift the rate it can pay you. If the Aussie dollar strengthens, it can pull the other way. You could see the same world metal price on two different weeks and still get a different local number because the dollar moved.

Supply and demand do their thing

When factories are busy, building is booming and demand for new copper wire, pipe and aluminium is high, prices tend to firm. When industry slows, or a big buyer pulls back, demand drops and so does the price.

Supply works the other way. If lots of scrap hits the market all at once, say after a spate of demolitions or a rise in prices that makes everyone clear out their sheds, there's more metal chasing the same buyers. That can soften prices for a while. It's a bit like fruit at the market. A glut pushes the price down, and a shortage pushes it up.

Freight and processing costs

Getting scrap from a Melbourne yard to the processor that wants it costs money. Shipping rates, port costs and even how busy the docks are can all affect what a yard can afford to pay. When freight gets dearer, the yard's margin gets squeezed, and the rate it offers can shift. It isn't glamorous, but it's a real part of the picture.

It isn't only the market. Your load matters too

All of the above explains why the market price moves. But a lot of the difference people notice between one week and the next is actually down to what they brought in.

Clean, sorted copper with nothing attached is graded at the top rate. The same weight of copper with solder, steel brackets and bits of plastic on it gets graded lower. Mixed piles are priced as the cheapest metal in them. So if last week's load was neatly sorted and this week's was a jumble, part of the gap is you, not the market.

The amount can matter as well. A big, well-sorted load may earn a better rate than a small mixed bucket, because it's cheaper for the yard to process and move on.

What it means for you

A few practical things follow from all this.

First, never assume last month's price still applies. If you haven't checked the rate recently, check it before you load the ute. It takes a minute and saves surprises at the weighbridge.

Second, don't try to time the market perfectly. Nobody can, including the people who trade metal for a living. If you've got scrap sitting around and the price looks reasonable, selling is usually better than waiting for a peak that may never come. Metal in the shed earns you nothing.

Third, if you have a large amount of scrap and no urgency, it can be worth checking the rate over a week or two to see which way it's heading. But only if holding on is easy and the metal is safe and out of the way.

Last, do the things you control. Sort your metals, strip off the easy extras, keep it clean and ask how it's graded. That's where you can reliably earn more, whatever the market's doing.

Questions people ask us

How often do scrap metal prices change in Melbourne? They can move daily, because they follow global markets. Many yards update their rates every few days or weekly, depending on how the market is behaving.

Why did I get a lower price than last time for the same metal? It could be the market, the exchange rate, or the grade of the load. Ask the buyer to explain how your metal was graded, because that's often the difference.

Is there a best time of year to sell scrap? Not reliably. Prices follow the global market more than the seasons. If you've got a decent amount of scrap and the rate is fair, selling now beats waiting.

Does the price differ between yards? Yes. Each yard has its own costs, buyers and grading, so rates can differ for the same metal on the same day. It's worth asking around.

Which metal's price moves the most? Copper tends to be the one people notice most, because it's valuable and heavily traded. But aluminium, brass and others move too.

Can I get a quote before I come in?

Send us a description or photo of your load and we'll give you a rough idea of what it's worth. The final price is confirmed once the metal is weighed and graded.
