The rule is not the same everywhere. Employers sit in three tiers, and knowing which tier a firm is in saves you weeks of wasted applications.
01The three tiers at a glance
Citizens only
Defence, DSTG, BAE Systems, Thales, ASC, Boeing Defence, Powerlink. A clearance or a citizenship rule screens everyone else out before reading.
Citizen or permanent resident
CPB and CIMIC, Lendlease, Downer, Jacobs, Transport for NSW, Victoria's transport department, the big four banks' technology programs.
Any unrestricted work rights
BHP, Rio Tinto, GHD, Aurecon, Arup, Fulton Hogan, John Holland, Transgrid, Atlassian, Canva, Google. Unrestricted by the start date is the test.
02Tier one: Australian citizens only
Defence and national security employers, because the work needs a security clearance. The Department of Defence graduate program requires Australian citizenship and a Negative Vetting 1 clearance. Defence Science and Technology Group is citizens only. BAE Systems requires citizens who are eligible for a clearance, and warns that nationality may be a factor under United States ITAR rules. Thales requires Australian citizens. ASC lists a police clearance, a Defence clearance and the ability to access protected US technology, and says applicants holding the nationality of certain countries are not eligible. Boeing Defence Australia requires citizenship.
One network business joins them: Powerlink Queensland lists Australian or New Zealand citizens only, with no permanent-resident option.
03Tier two: citizen or permanent resident
Many contractors and public bodies. CPB Contractors and the CIMIC group take Australian or New Zealand citizens or Australian permanent residents, and ask for passport or residency evidence at application. Lendlease and Downer are citizen or PR. Jacobs lists citizenship or PR. Transport for NSW, Victoria's transport department and the big four banks' technology programs are citizen or PR too. CommBank excludes bridging visas and the subclass 820 partner visa explicitly.
04Tier three: any unrestricted work rights
The miners and the big consultancies are the most open. BHP says international students with a valid visa are welcome to apply and must hold a visa with no work restrictions by the February start. Rio Tinto accepts student and post-study work visa holders. GHD lists bridging visas among its accepted classes. Aurecon takes working-visa holders, Arup asks for full working rights, Fulton Hogan accepts any work rights including student and graduate visas, John Holland takes full working rights, and Transgrid accepts eligible work visas.
In software, Atlassian accepts student-visa holders with full post-study work rights and is a sponsor, and Canva and Google ask only for the right to work in Australia.
Worth knowing
Unrestricted by the start date is the phrase to watch. A student visa with its hour limit is fine to apply on, but you must hold a post-study or other unrestricted visa by the day the program starts.
05What a security clearance actually involves
A clearance is sponsored by the employer and issued by the Australian Government Security Vetting Agency; you cannot apply for one yourself. Levels run from Baseline through Negative Vetting 1 and 2. Defence graduates need NV1. The check covers your background and history and takes time, which is why defence offers arrive months after interview and why the clearance is a condition of the offer rather than a step before it.
ITAR is a separate United States export-control regime. Where a project involves US-controlled technology, an employer may have to consider your nationality, including dual nationality, before placing you. BAE and ASC say this on their pages. Ask the recruiter early rather than finding out at offer.
06Other gates that surprise students
- A current driver's licence, which Jacobs and Downer require and site employers generally expect.
- Willingness to do fly-in fly-out or relocate, which BHP and Fortescue state for site roles.
- A pre-employment medical with drug and alcohol testing at miners and some contractors.
- Flexibility for night shift and weekends at contractors such as Fulton Hogan.
- A degree completed within a stated window, often the last two years.
07If you are an international student
Aim at tier three first and spend the most effort there. Read the work-rights line on every posting before you write a word. Make sure your visa pathway gives you unrestricted work rights by February of the start year, because that is the test BHP and others apply. Do not apply to tier one; the application is screened out before anyone reads it. For tier two, check the exact wording, because a few firms accept New Zealand citizens and others specify Australian PR.
Common questions
Can international students get engineering graduate jobs in Australia?
Yes, at employers that accept any unrestricted work rights, including BHP, Rio Tinto, GHD, Aurecon, Arup, Fulton Hogan, John Holland and Transgrid. Defence employers require Australian citizenship, and many contractors and government bodies require citizenship or permanent residency.
Do I need Australian citizenship to work at BAE Systems or Thales?
Yes. Both require Australian citizens, and BAE requires eligibility for a Defence security clearance. Nationality, including dual nationality, can also matter under US ITAR rules.
What is an NV1 security clearance?
Negative Vetting 1 is the clearance level the Department of Defence graduate program requires. It is sponsored by the employer, issued by the Australian Government Security Vetting Agency, and takes months, so it is usually a condition of the offer.
