The University of NSW Facebook page has been hacked for the second time in as many days. ​

The university posted a series of photos of Lebanese-American porn star Mia Khalifa on Sunday night, along with links to "extreme curves" and suggestions on the top universities in Italy.

The second round of hacking at the eastern suburbs institution came after it had to scramble to remove similar updates on Saturday - when its open day was marred by posts that included "the internet is freaking out about this Mexican weatherwoman".
