The students will spend two years studying for a diploma of adventure tourism management or a diploma of hospitality.
The adventure tourism management two-year diploma is the only one of its kind in New Zealand.
It develops future adventure tourism managers by blending business management and leadership skills with practical work experience and adventure education.
As part of their diploma, every student receives six months of fully paid industry training with an adventure tourism business.
Graduates can continue on to a bachelor's degree at Thompson Rivers University in Canada.
Hospitality students also spend six to nine months working fully paid within the industry in Queenstown.
QRC delivers the diploma of hospitality management in partnership with the International College of Management in Sydney (ICMS) and César Ritz Colleges, of Switzerland.
This international hotel management qualification opens the doors to higher study and exciting careers throughout the world.
Joining the international students are New Zealanders from Whangarei, Auckland, Taranaki, Waikato, Wellington and Christchurch.
QRC domestic marketing and recruitment manager Sarah Cairns said the six Australian students, a new and growing market for the college, were all studying adventure tourism.
"They all have very interesting backgrounds, and four have been in the industry for the past few years.
"They're the perfect target market were aiming at, either school leavers or approaching their early 20s with life skills and work history, but looking to take the next step towards becoming future tourism managers with real business management and leadership skills," she said.
QRC chief executive Charlie Phillips said the college was delighted with the number and calibre of students in its latest intake.
"These are optimum class numbers and they're here to learn from the industry's best in an environment that provides hands-on learning in Queenstown, a town renowned for its wealth of tourism and hospitality infrastructure.
"I'm confident that in two years' time they'll emerge as fully fledged professionals who'll hit the ground running."
