Diploma of Horticulture

The Diploma of Horticulture at Brisbane College of Horticulture is a one-year qualification for people who want to work with plants, soil and growing systems at a technical level. You study how plants grow, how to propagate and establish them, how to manage soil, water and nutrition, and how to identify and deal with pests, diseases and weeds. Nursery production, landscape and turf work, and the practical side of running a horticultural operation all sit within the diploma. Assessment is a mix of theory and hands-on tasks, and you will spend time in growing spaces rather than only in a classroom.

How the qualification is structured

The diploma runs for one year full time and sits at the diploma level of the Australian Qualifications Framework. Like most Australian diplomas, it is built from units of study, each with a set credit point value, and you need to complete the required units to graduate. Delivery is typically across semesters or trimesters, and the college can confirm the exact sequence, unit list and any recognition of prior learning arrangements. There is no honours year attached to a diploma; if you want to go further, you can use the diploma as a pathway into a bachelor degree in horticulture, agriculture or environmental management, often with credit for completed units.

What you learn

You come out able to plan and carry out horticultural work with less supervision. That means reading a site, choosing and propagating plants, scheduling irrigation and feeding, monitoring for pests and disease, and keeping records that meet workplace and regulatory requirements. You also build the communication and planning skills that let you supervise a small team or deal directly with clients, suppliers and land managers. Work-integrated learning is common in this field, and the college can advise on placement or industry-based components.

Who it suits

This diploma suits school leavers who want a practical qualification without committing to a three-year degree, career changers moving into nurseries, landscaping, parks and gardens or production horticulture, and people already working in the industry who want formal recognition of their skills. International students should note that the Student visa allows up to 48 hours of work per fortnight while your course is in session, and graduates may be eligible for the Temporary Graduate visa (subclass 485) post-study work stream, subject to the Department of Home Affairs requirements. English proficiency is required for international applicants, commonly IELTS Academic 6.0–6.5 overall for coursework at this level, with TOEFL iBT, PTE Academic, Cambridge C1 Advanced and the college's own English programmes accepted as equivalents. Confirm tuition, intake dates, English requirements and unit details on the official CRICOS listing and with the college before you apply.
