In 2019 we surveyed Australian early career researchers (ECRs) working in STEMM (science, technology, engineering, mathematics and medicine). ECRs almost unanimously declared alove of research, however, many reported frequent bullying and questionable research practices (QRPs), and that they intended to leave because of poor career stability. We replicated the survey in 2022 to determine the impact of the COVID-19 pandemic and sought more information on bullying and QRPs. Here, we compare data from 2019 (658 respondents) and 2022 (530 respondents), and detail poor professional and research conditions experienced by ECRs. Job satisfaction declined (62% versus 57%), workload concerns increased (48.6% versus 60.6%), more indicatednow is a poor time to commence a research career(65% versus 76%) from 2019 to 2022, and roughly half reported experiencing bullying. Perhaps conditions could be tolerable if the ecosystem were yielding well-trained scientists and high-quality science. Unfortunately, there are signs of poor supervision and high rates of QRPs. ECRs detailed problems likely worthy of investigation, but few (22.4%) felt that their institute would act on a complaint. We conclude by suggesting strategies for ECR mentorship, training, and workforce considerations intended to maintain research excellence in Australia and improve ECR career stability.
