Earlier this year, there's news that the DIBP will be accepting alternative English Language test scores for Visa Applicants in early 2015. The Department has now released the news that starting from 23 November 2014, they will accept test scores from alternative English Language tests for visa applicants.
The following tests will be accepted by DIBP in place of IELTS and OET:

1. Test of English as a Foreign Language internet-based test (TOEFL iBT)
2. Pearson Test of English Academic (PTE Academic)
3. Cambridge English: Advanced (CAE)*

*Cambridge English: Advanced (CAE) will be accepted only if the test has been taken on or after 1 January 2015. This is so that it would coincide launch of Cambridge English Language Assessment's new reporting system.
