Astronaut salary in Australia: what reaches your bank account after tax

Astronaut pay in Australia is not publicly available because there is no domestic crewed space program; overseas roles vary widely and are highly competitive.

How to compare a job offer using the amount that reaches your account

When you receive a job offer, the headline figure can be misleading. What matters is the amount that lands in your bank account after tax and the Medicare levy. This guide uses the example of an astronaut salary to show you how to work out your take-home pay, even though astronaut roles are not available in Australia.

Why astronaut salary is not a standard Australian figure

The Australian Space Agency explains that Australia does not currently have plans for a crewed space program, so astronaut roles are only available overseas. Space agencies such as NASA, ESA, JAXA, CSA and Roscosmos run highly competitive selection processes, and applicants must be citizens of the relevant country. No Australian salary guide publishes an astronaut salary because there is no domestic market. However, the government's Careers in Space booklet lists salaries for related space careers, such as flight surgeons (entry level $324,000, experienced $688,000) and aerospace engineers (entry level $76,000, experienced $140,000). These figures can help you benchmark if you are considering a space-related role in Australia.

Applying the tax rules to any salary

Whether you are looking at a flight surgeon salary or a more typical role, the tax calculation is the same. For the 2026–27 tax year, the resident tax rates are:

$0 – $18,200: nil
$18,201 – $45,000: 15c for each $1 over $18,200
$45,001 – $135,000: $4,020 plus 30c for each $1 over $45,000
$135,001 – $190,000: $31,020 plus 37c for each $1 over $135,000
$190,001 and over: $51,370 plus 45c for each $1 over $190,000

You can also claim the Low Income Tax Offset (LITO) if your taxable income is below $66,667. The maximum LITO is $700 at incomes up to $37,500, then it reduces by 5c per dollar until $45,000, then by 1.5c per dollar until it reaches zero at $66,667.

Medicare levy: what you pay

The Medicare levy is 2% of your taxable income. If you are single and your income is below $28,011, you pay no levy. Between $28,011 and $35,013, you pay a shaded rate of 10c per dollar over $28,011. Above $35,013, you pay the full 2%. These are the latest published single-person thresholds. For a full-time worker earning above $35,013, the levy is simply 2% of your taxable income.

Example: take-home pay for a $324,000 salary

Let's say you are offered a flight surgeon role at $324,000 per year (plus super). First, note that super is not deducted from your salary; it is paid on top by your employer at 12% (from 1 July 2026) up to a maximum contribution base of $270,830. Your take-home pay is calculated on the $324,000.

Tax: $51,370 + 45c × ($324,000 – $190,000) = $51,370 + $60,300 = $111,670
LITO: Not applicable (income above $66,667)
Medicare levy: 2% × $324,000 = $6,480
Total deductions: $111,670 + $6,480 = $118,150
Annual take-home: $324,000 – $118,150 = $205,850
Fortnightly take-home: $205,850 ÷ 26 = $7,917.31

This is the amount that would reach your bank account each fortnight, assuming no HELP/HECS repayments, Medicare levy surcharge, or salary sacrifice arrangements.

Using take-home pay to compare offers

When you compare job offers, always convert each to take-home pay using the same method. A role with a lower headline salary but better benefits (like salary packaging or a higher super rate) might leave you with more cash in hand. Use our Take-home pay guide for a step-by-step calculator approach, and check the Tax and Medicare page for the latest rates.

Remember that the national minimum wage is $26.44 per hour or $1,004.90 per week (from 1 July 2026). Any offer should at least meet that. For space careers, the salaries are well above the minimum, but the same tax principles apply.

Final note

This estimate is not a tax assessment. Your actual take-home pay may differ if you have other deductions, offsets, or a Medicare levy surcharge. Always consult the Australian Taxation Office or a tax professional for your personal situation.

Questions

What is the typical astronaut salary in Australia?

Australia does not have a crewed space program, so astronaut roles are only available overseas through agencies like NASA, ESA, JAXA, CSA or Roscosmos. Salaries for those roles are set by the respective agency and are not published in Australian salary guides. The Australian Space Agency notes that applications are highly competitive and require citizenship of the relevant country. For related space careers in Australia, the government's Careers in Space booklet shows median salaries for roles such as flight surgeons (entry level $324,000, experienced $688,000) and other space professionals, but not for astronauts themselves.

How do I compare a job offer using take-home pay?

Start with the annual salary quoted in the offer. If it says 'plus super', add 12% super (from 1 July 2026) to the salary to get the total package, but remember super is not cash in hand. Then apply the 2026–27 resident tax rates: nil on the first $18,200, 15c per $1 from $18,201 to $45,000, 30c per $1 from $45,001 to $135,000, 37c per $1 from $135,001 to $190,000, and 45c per $1 above $190,000. Subtract the Low Income Tax Offset (maximum $700, phasing out between $37,500 and $66,667). Then add the Medicare levy: full-time salaries pay the full 2%, unless your income is below the single threshold of $28,011 (no levy) or between $28,011 and $35,013 (shaded rate of 10c per $1 over $28,011). The result is your annual take-home pay. Divide by 26 for fortnightly amount.

What tax and Medicare apply to high salaries like those in space careers?

For high salaries, the top marginal rate of 45c per $1 applies above $190,000. The Medicare levy is a flat 2% on taxable income with no upper limit, so a $324,000 salary would incur a $6,480 Medicare levy. There is no Medicare levy surcharge unless you have private hospital cover or pay the surcharge. The Low Income Tax Offset does not apply above $66,667. Superannuation guarantee is 12% on earnings up to $270,830, but that is paid by your employer and is not part of your take-home pay. Always check if the salary is quoted inclusive or exclusive of super.
