More than 2,150 students, including more than 600 ACT school-leavers, have received an early offer to study at The Australian National University (ANU) in 2016.

The offers were made through the Universities Admissions Centre's (UAC) early January round.

Future students still have time to apply to study at ANU and can change their preferences through the UAC any time before midnight on Wednesday 6 January. ANU will make further offers in the UAC Main Round on Wednesday 20 January.

ANU Vice-Chancellor Professor Brian Schmidt AC welcomed some of the new students and said demand for places to study at ANU remained strong in 2016.

"ANU continues to be the university of choice for talented young people from across the nation and overseas," Professor Schmidt said.

Demand for domestic undergraduate places remains strong, with first preference applications up 13 per cent compared to 2015.

In particular, demand for Flexible Double Degrees at ANU increased with 1,198 offers made so far in 2016, compared to 767 at the same time in 2015.

Early offers were made to 638 ACT school leavers. ACT school-leavers who placed ANU as a first preference were considered for early offers.

Hannah Chan, who has been offered a place to study a Flexible Double Degree in Engineering and Advanced Computing, said she was delighted to receive an early offer to study at ANU.

"It feels amazing - it is really exciting," she said. "It is a beautiful campus, and secondly the people at ANU are amazing."

Callum Sambridge has been offered a place to study a Bachelor of Science (Advanced) (Honours) after completing an ANU extension course in physics during his year 12 studies.

"That course really inspired me to come to ANU, with all of resources here, and it is right at my back door," he said. "It feels incredible."

Therese McMahon has been offered a place to study a Bachelor of Arts/Master of International Affairs.

"It is wonderful and very exciting. I looked at a few places, and ANU just had this magnetism about it," she said.
