The Bachelor of Advanced Science (Honours)/Bachelor of Engineering (Honours) is a prestigious double degree that combines intensive, research-focused scientific training with professional, accredited engineering education. Unlike a standard Bachelor of Science, the Advanced Science component includes advanced-level coursework, a research-based Honours year, and specialised pathways tailored to high-achieving students' interests. Students begin with strong foundations in mathematics, chemistry, physics, and biology before branching into more than 25 advanced science disciplines — from microbiology and geology to advanced physics and environmental science — while simultaneously building engineering competency across specialisations ranging from traditional civil and electrical engineering through to modern fields like renewable energy, biomedical, and quantum engineering.

This dual degree is designed for academically motivated students who want to bridge the worlds of scientific inquiry and applied engineering practice. Students develop the critical and analytical thinking skills needed to complete a supervised research project in their Honours year, and also apply themselves to engineering design, professional engineering practice, technical management, and real-world problem-solving throughout their engineering studies. The breadth of the program means graduates are uniquely positioned to operate at the intersection of science and engineering — conducting research that informs engineering solutions, or applying rigorous scientific understanding to complex technical challenges.

Graduates are sought after by a wide range of Australian and global employers including engineering consultancies, mining and resources companies, renewable energy firms, biotechnology and pharmaceutical companies, government research agencies (such as CSIRO and ANSTO), defence contractors, telecommunications providers, environmental consultancies, and technology companies. The dual accreditation — through an embedded Honours year in science and an Engineers Australia-accredited engineering qualification — makes graduates eligible for professional membership of Engineers Australia, the peak body for the engineering profession in Australia, and opens international career pathways through the Washington Accord.

Entry into this dual degree is competitive and typically requires a high Australian Tertiary Admission Rank (ATAR), generally in the range of 85–99 depending on the institution and engineering specialisation chosen. Most Australian universities require applicants to have completed Year 12 (or equivalent) with strong results in Mathematics (Extension or Advanced level is typically expected or assumed), Chemistry, Physics, and English. Some institutions list Mathematics Extension 1 and Physics as assumed knowledge for the engineering component, and Mathematics plus Chemistry for the advanced science component, with additional subject prerequisites varying based on the chosen science major. Applicants are typically assessed through ATAR and selection rank, with adjustment factors available for students from regional areas, schools with low tertiary participation rates, or through Indigenous admission schemes.

For international students, English language proficiency requirements apply. Most Australian universities require an IELTS overall band score of 6.5–7.0 (with no individual band below 6.0), or equivalent results in TOEFL, PTE Academic, or the Cambridge English exam. Some institutions accept completion of an approved English preparation program as an alternative pathway. Mature-age applicants, those with prior tertiary study, or students who have completed a TAFE or VET qualification may be considered through alternative entry pathways or recognition of prior learning (RPL) arrangements, where completed subjects equivalent to those in the program may reduce credit load. Domestic applications are typically processed through state-based tertiary admissions centres such as UAC (NSW), VTAC (Victoria), QTAC (Queensland), SATAC (South Australia) and TISC (Western Australia).

Entry into the Honours year within the Advanced Science component is subject to satisfactory academic performance and progression requirements during the first three years of study. Students who do not meet the academic threshold for Honours entry may have the option to exit with a standard Bachelor of Science award. Industrial training or approved work experience — often a minimum of 60 days — is also required as part of the engineering component at many universities, and students are encouraged to arrange this through industry placement programs offered by their faculty.
