If I want to hold my ceremony internationally, can I use a friend as my celebrant ?

We are wanting to have a destination wedding and a lot of the venues are providing non-legal wedding celebrant. Could we just get our fiend to officiate the ceremony instead of using these ? We will be coming back to Aus and getting officially married at a registry, we just want the non-legal ceremony and reception. Please let me know if anyone knows if this is possible.
