Universities and scientific research in the USA are facing a dire future. Understandably, some scientists are considering leaving the USA. I have had a few enquiries about Australia. This makes sense, as Australia is a stable English-speaking country with similarities in education, culture, democracy, and economics. At least compared to most other possible destinations. Nevertheless, there are important differences between Australia and the USA to be aware of, particularly when it comes down to how universities function (and dis-function!) and how they hire people.
A few people have asked me for advice. Below are some comparisons. Why should you believe me? I spent eleven years in the US (1983-1994) and visited at least once a year until 2018. On the other hand, there are some reasons to take what I say with a grain of salt. I have never been a faculty member in a US university. I retired four years ago from a faculty position in Australia. I actually haven't sat on a committee for almost ten years :). Hopefully, this post will prompt other readers to weigh in with other perspectives.
There are discussions in Australia about trying to attract senior people from the USA to come here. Whether that will come to anything substantial remains to be seen.
The best place to look for advertised positions is on Seek.
Postdocs
This is where the news is best. Young people in the USA can apply for regular postdoc positions. Most are attached to specific grants and so involve working on a specific project.
Ph.D. students
Most of the positions go to Australian citizens who get there own scholarship (fellowship) from the government. These are not tied to a grant or a supervisor (advisor) There are a few positions for international students, but not many. Usually they go to applicants with a Masters degree and publications.
Ph.D's are funded for 3 to 3.5 years. There is no required course work. Australian students have done a 4-year undergraduate degree and no Masters. This means tackling highly technical projects in theory is not realistic, except for exceptional students.
Faculty hiring is adhoc
There is no hiring cycle. Positions tend to be advertised at random times depending on local politics, whims and bureaucracy. Universities and Schools (departments) claim they have strategic plans, but given fluctuations in funding, management, and government policy positions appear and disappear at random. Typically, the Dean (and their lackies), not the department, control the selection process, particularly for senior appointments. The emphasis is on metrics. Letters of reference are sometimes not even called for before short listing. Some hiring is done purely from online interviews and seminars.
Bias towards insiders
People already in the Australian system know how to navigate it best. They may also already have a grant from the Australian Research Council and have done some teaching and (positive) student evaluations. They are known quantities to the managers and so a safer bet than outsiders. If you want to get a junior faculty position here (a lectureship) your chances may be better if you first come as a postdoc. However, there are exceptions...
Current funding crunches
Unfortunately, I fear the faculty market may be quite cool for the next few years. Many universities are actually trying to sack (fire) people due to funding shortfalls. These budget crises are due to post-covid, mismanagement, and the government trying to reduce international student numbers (due to the politics of a housing and cost-of-living crisis).
Australian Research Council
This is pretty much the sole source of funding in physics and chemistry. This is quite different to the USA where there were (pre-Trump) numerous funding agencies (NSF, DOE, DOD, ...). They are currently reviewing and redesigning all their programs and so we will have to wait to see how this may impact the prospects of scientific refugees from the USA. (They used to have quite good Fellowship schemes for all career stages that were an excellent avenue for foreigners to come here). Some of my colleagues recommend following ARC Tracker on social media to be informed about the latest at ARC.
Thirty years ago, I came back to Australia from the USA. I had a wonderful stint doing science, largely because of generous ARC funding. Unfortunately, the system has declined. But I am sure it is better than being the USA right now.
There are many more things I could write about. Some have featured in previous rants about metrics and managerialism. Things to be aware of before accepting a job include faculty having little voice or power, student absenteeism, corrupt governance, and there is no real tenure or sabbaticals.
