hi, i am currently a dental student in Australia, and i think there is this 'bridging program for foreign trained dentists' at dental schools in Australia that you can be enrolled in.
there are only 5 dental schools in australia, so you might wanna visit their web-sties to get the appropriate info regarding the programs.
1. univ of sydney
2. univ of melbourne
3. univ of adelaide
4. univ of western australia
5. univ of queensland
i hope that i was helpful!
ask questions freely if you want to.
