Day-to-day
Extract, clean, and transform raw data from multiple sources including databases, APIs, and data warehouses using Python, R, or SQL to prepare datasets for analysis. Explore data distributions and relationships using exploratory data analysis techniques and visualisation libraries such as matplotlib, ggplot2, or Tableau to identify patterns and anomalies. Design and conduct statistical hypothesis tests and A/B experiments to validate assumptions and measure the impact of proposed changes or features. Build and train supervised and unsupervised machine learning models using scikit-learn, TensorFlow, or similar frameworks to predict outcomes or segment populations. Evaluate model performance using appropriate metrics such as precision, recall, F1-score, or RMSE, and conduct cross-validation to assess generalisation to unseen data. Deploy machine learning models to production environments and establish monitoring pipelines to track model drift and performance degradation in live systems. Collaborate with software engineers to integrate models into applications and APIs, ensuring models meet latency, scalability, and reliability requirements. Document methodologies, assumptions, and limitations in technical reports and present findings to business stakeholders with varying levels of statistical literacy.

Bachelor degree or higher (ABS skill level 1)
Can employers fill these jobs
Employers hiring for this occupation were generally able to find suitable applicants in 2025. This measures how hard employers found it to fill jobs. It is not a count of jobs, and it does not say whether the occupation is growing.
Requirements
The standard entry pathway requires a bachelor degree or higher (ABS Skill Level 1). Specific qualification requirements vary by employer and state. Some employers may accept equivalent experience. Check yourcareer.gov.au for available courses and dewr.gov.au/skills-reform/free-tafe for subsidised training options.
The honest hard part
You'll hit a hard ceiling without a maths or computer science degree. Career changers without formal quantitative training spend 1 to 2 years playing catch-up on linear algebra, probability, and programming before landing decent roles. Even then, you'll compete against graduates who did this in their sleep. The pay also plateaus quickly unless you move into management or find a niche.
Where the jobs are
Government agencies (ABS, Centrelink) hire regularly but pay less. Regional Australia has almost none. Most roles are office-based, though some tech companies offer remote work. Check LinkedIn job boards and company careers pages for real openings.
