Although the University of Canberra is mentioned in the question, it is certain that the Australian National University (ANU) accepts the online scores of ACT, because ACT is a standardized test in Australia to measure students' academic ability and university preparation ability. Therefore, most Australian higher education institutions accept ACT scores as one of the admission criteria. In addition, ANU's admissions website also explicitly mentions accepting ACT scores.

If you plan to apply for ANU, you can choose to submit your scores to ANU during the ACT exam. If you have already taken the ACT exam, but have not chosen to submit your scores to ANU, you can send your scores to ANU through the official website of ACT (www.act.org). If you have any questions, please contact ANU Admissions Department or act Test Center for consultation.

In addition to ACT scores, ANU also requires applicants to provide other materials, such as high school transcripts, letters of recommendation, personal statements, etc. Therefore, according to the specific requirements of ANU, applicants need to prepare other application materials after completing the ACT exam in order to successfully apply for ANU.

In short, the Australian National University (ANU) accepts ACT online scores. Applicants can choose to submit their scores to ANU during the ACT exam or send them to ANU through the official website of ACT. At the same time, applicants need to prepare other application materials according to the requirements of ANU in order to successfully apply for admission.
