Managing Money When It Comes in Big Chunks

So you’ve landed your first FIFO role and your worlds about to change for good. Most mining roles are moving to 7/7 rosters these days, meaning you’ll probably work a week, then break for a week, before flying back to do it all again. Companies will typically pay on a fortnightly cycle and often this lines up with your break week, which is great.

But what to do with your new found riches? Well, before you go counting your chickens before they’ve hatched, let me breakdown an example of what is paid, what is deducted, and what is left, so you don’t get a shock when that first payslip hits your email.

I work in Service Crew, which is typically paid at a rate that ranges between AUD$50-60 p/h. For a 12 hour shift, which is standard for a shift within an underground mine, that equates to between AUD$600-$720 per shift. On a 7/7 roster, that translates to between AUD$4200-$5040 gross for the period. Not bad, not bad. But say hello to my little friend…

The ATO takes a serious bite out of FIFO earnings, and the size of that bite surprises a lot of first-timers. Because your income is concentrated into short, high-earning periods, the tax withheld on each payslip is calculated as though you earn that amount every fortnight, all year round. You don’t, but the withholding doesn’t know that. The result is that your employer withholds at a higher marginal rate than your actual annual liability warrants, which means most FIFO workers are owed a refund at tax time rather than a bill. That refund can be meaningful; treat it as a feature, not a surprise.

On the numbers above, expect somewhere between 30-35% to disappear before it hits your account once you factor in income tax and the Medicare levy. On the lower end of the Service Crew range that leaves you with roughly AUD$2,700-$2,900 in hand for the fortnight. On the upper end, closer to AUD$3,200-$3,400. Real money, but less dramatic than the gross figure suggests.

The Problem With Irregular Income

The psychological trap with FIFO pay isn’t that the money is bad, it’s that it arrives in a lump and feels enormous in the moment. Most people are conditioned to managing a modest weekly or fortnightly trickle. When a few thousand dollars lands at once, the brain doesn’t naturally spread it across the coming weeks. It reads it as surplus. That’s where the money goes.

This is compounded by the camp lifestyle itself. On swing you have almost no expenses… accommodation, meals, and transport are covered. Your spending is minimal. Then you come home and decompress, and decompression has a habit of being expensive. A week off with nothing structured and cash in the account is a reliable way to find out how fast money moves.

The fix isn’t willpower. It’s structure.

A Simple Framework That Actually Works

The core idea is to stop treating each pay as income for the current period and start treating it as income for the full roster cycle. On a 7/7 that means each fortnightly pay needs to cover two weeks, not one.

Split your account on day one. Set up a separate account. Most banks let you open a fee-free secondary savings account online in minutes, and on payday, move a fixed percentage into it immediately, before you do anything else. This is your savings and investment allocation. It leaves your transaction account before your brain can spend it.

A workable starting split for someone getting started:

• 50% to fixed costs: rent or mortgage, insurance, subscriptions, anything with a regular due date
• 20% to savings and investment
• 20% to a float account for living expenses during your break week
• 10% discretionary

The exact percentages matter less than the habit of splitting immediately and consistently. Adjust as your situation develops.

Pay your fixed costs on payday. Don’t let bills accumulate and surprise you mid-break. Know what’s due and clear it on the day the money arrives. What’s left is yours with no hidden obligations attached.

Give your break week a budget. This sounds obvious but almost nobody does it. Decide before you fly home what you’re comfortable spending during your time off. Not as a restriction… as a target. It changes the psychology. You’re spending toward a number rather than spending until the account runs low.

What To Do With the 20%

This is where it gets interesting and where most FIFO workers leave serious money on the table.

The income potential in mining is genuinely unusual. The combination of high hourly rates, long shifts, and minimal on-site expenses means a disciplined FIFO worker can save at a rate most people in conventional employment can’t touch. But that only matters if the savings are doing something useful rather than sitting in a transaction account earning 0.1% interest.

At minimum, your savings should be in a high-interest savings account or offset account if you have a mortgage. Beyond that, the two most common paths for FIFO workers building toward financial independence are property and index funds – both straightforward, both well-suited to irregular income, and both worth a dedicated post of their own.

For now, the principle is simple: decide what the 20% is for before the pay arrives. Whether that’s an index fund contribution, an offset account top-up, or a property deposit fund – have the destination ready so the money moves automatically.

The Tax Return Is Not a Bonus

One last thing worth saying plainly: your end-of-year tax refund is not found money. It’s your own income that was withheld at too high a rate and returned to you months later, interest free to the government. Treating it as a windfall and spending it is a common and costly mistake.

Calculate your expected refund, factor it into your annual savings plan, and deploy it the same way you deploy every other pay. If you’ve done the rest of this right, you’ll already know exactly where it’s going before it arrives.
