Astrophysicist Salary in Australia: What You Take Home After Tax

How to Estimate Your Take-Home Pay as an Astrophysicist

If you're an astrophysicist working in Australia, you probably want to know how much of your salary actually lands in your bank account after tax and the Medicare levy. This guide walks you through the numbers using publicly available data from PayScale and Jobs and Skills Australia.

What the Data Says About Astrophysicist Salaries

According to PayScale, the average astrophysicist salary in Australia is AU$82,601 per year, with a median of AU$82,601. The range typically falls between AU$59,000 and AU$121,000, based on 23 salary profiles updated in September 2026. Early-career astrophysicists (1–4 years) earn around AU$81,389, while mid-career (5–9 years) earn about AU$87,429. Jobs and Skills Australia notes that physicists (including astronomers) have a median age of 41, 87% work full-time, and 82% hold a postgraduate qualification. However, they do not publish median weekly earnings for this specific 6-digit ANZSCO occupation.

Calculating Your Take-Home Pay

To work out what clears after tax, you need to apply the 2026–27 resident tax rates and the Medicare levy. Let's use the median astrophysicist salary of $83,000 as an example.

Step 1: Income tax

• Taxable income: $83,000
• Tax on first $45,000: $4,020
• Tax on remaining $38,000 at 30c: $11,400
• Gross tax: $15,420
• Less Low Income Tax Offset (LITO): $325 (since $83,000 is above $66,667, the offset is reduced to $325)
• Net tax: $15,095

Step 2: Medicare levy

• Full 2% applies because $83,000 exceeds the single upper threshold of $35,013.
• Medicare levy: $1,660

Step 3: Take-home pay

• Annual: $83,000 – $15,095 – $1,660 = $66,245
• Fortnightly: $66,245 ÷ 26 = $2,548
• Weekly: $66,245 ÷ 52 = $1,274

This is an estimate only. Your actual take-home may differ if you have HELP/HECS debt, salary sacrifice arrangements, or if your employer uses payroll tax-table rounding. The Medicare levy surcharge may also apply if you do not have appropriate private hospital cover and your income exceeds $93,000.

Factors That Affect Your Astrophysicist Salary

Your actual astrophysicist salary can vary significantly based on:

• Experience: PayScale shows late-career astrophysicists earn about 4% more than the median.
• Employer: Universities, government research agencies (like CSIRO), and private sector roles may offer different pay scales.
• Location: Salaries in Sydney and Canberra tend to be higher than in regional areas.
• Specialisation: Astronomers, particle physicists, and medical physicists may have different pay structures.

Superannuation and Your Take-Home Pay

Most astrophysicist salaries are quoted as base salary excluding super. From 1 July 2026, the super guarantee rate is 12%, meaning your employer must contribute an additional 12% of your ordinary time earnings (up to $270,830 per year) into your super fund. This does not reduce your take-home pay – it's on top of your salary. So if your base is $83,000, your total package including super is about $92,960.

Summary

The typical astrophysicist salary in Australia is around $83,000 per year, giving a take-home pay of roughly $66,200 annually or $2,548 per fortnight. Remember that this is before any voluntary salary packaging or additional deductions. Always check your pay slip and consult a tax professional for your specific situation.
