South Australia Take-Home Pay Calculator 2025: Federal Income Tax + Medicare Levy

Adelaide and the AUKUS opportunity

Adelaide is the planned construction site for Australia's nuclear-powered submarine fleet under the AUKUS agreement (with the US and UK). Construction will create thousands of high-paying defence-sector jobs over the next two decades, particularly nuclear engineering, naval architecture, manufacturing trades, and project management roles. The first submarines under the AUKUS pact are expected to be delivered to Australia in the late 2030s.

Major defence employers in Adelaide include BAE Systems Australia (Hunter-class frigate construction at Osborne), ASC Pty Ltd (Collins-class submarine sustainment), Babcock (Hunter River Combat System), and the Australian Naval Infrastructure agency. The defence sector is the largest single sectoral driver of Adelaide's projected medium-term growth.

For a $100,000 Adelaide defence-tech professional, SA take-home is roughly:

• Federal income tax: ~$22,500
• Medicare Levy: ~$2,000
• Total deductions: ~$24,500
• Net take-home: ~$75,500

Identical to other Australian states at the same income. Adelaide's advantage is lower housing costs (median home prices roughly 55 percent of Sydney) and the AUKUS-driven career trajectory in defence and engineering.

Adelaide cost of living and quality of life

Adelaide consistently ranks high in liveability surveys (Economist Intelligence Unit consistently places Adelaide in the global top 10). The city has a compact urban form, substantial parks and green space, strong arts and cultural scene (Adelaide Festival, Fringe Festival), and proximity to wine regions and beaches. Day-to-day expenses are similar to other Australian capitals, but housing is meaningfully cheaper than Sydney or Melbourne.

Median rent for a 2-bedroom inner-Adelaide apartment around AUD $450/week. For a single $80k earner, housing typically consumes 25 to 35 percent of take-home pay in Adelaide versus 35 to 45 percent in Sydney.

South Australian wine industry

SA produces approximately 50 percent of Australian wine by value, with the Barossa Valley, McLaren Vale, and Clare Valley being the most internationally-renowned regions. The wine industry supports substantial employment in viticulture, winemaking, hospitality, and exports. Average wages in the wine industry are below the Adelaide professional average but combined with wine-industry lifestyle factors (regional living, seasonal patterns), the sector retains a strong workforce.

SA state-administered taxes

• Payroll tax: 4.95 percent on wages above $1.5M (employer-paid).
• Stamp duty: 4 to 5.5 percent on property purchase price.
• Land tax: 0.5 to 2.4 percent on investment property above $755,000 threshold.
• First Home Owner Grant: $15,000 for first-home buyers of new homes under $650,000.

Adelaide tech and space sectors

Beyond defence, Adelaide has emerged as Australia's space sector hub. The Australian Space Agency is headquartered in Adelaide (established 2018), and major space tech firms include Fleet Space Technologies, Inovor Technologies, and the SA Government-supported Space Innovation Centre. The space sector is expected to create thousands of high-tech jobs in Adelaide over the next decade as Australian space industry capacity grows.

Adelaide's tech ecosystem more broadly includes Lot Fourteen (the major Adelaide innovation precinct in the former Royal Adelaide Hospital site), the Adelaide Smart City initiative, and a growing concentration of fintech and SaaS startups. Tech salaries in Adelaide are typically 75 to 85 percent of Sydney/Melbourne equivalents. The combination of competitive tech salaries, lower cost of living, and emerging space and defence sector opportunities has made Adelaide an attractive destination for tech professionals seeking lifestyle balance and career growth.

SA public service

South Australian Government employs approximately 95,000 people. The SA Public Service Act classifications produce structured salary ranges. Major employers include SA Health, Department for Education, SAPOL (police), and Renewal SA. SA public servants receive 11.5 percent employer superannuation and standard leave entitlements.
