You could also send unsolicited applications to the potential employers and practices in your country of residence. I am unsure if you would be able to get the trainee role abroad, this could be a move in the future after gaining experience for good few years.
Intially you should have a clearly layed out CV with your academic achievements and distinctions. In order to substitute your work expereience part of your CV try to get the brief testimonials from your professor or tutor which gives and indication of your professional aptitude and keeness of developing as an accountant with a consistent approach.
Your cover letter can play a significant role which will give affirmation to the employer that you are a quick learner and willing and able to contribute to the organisation despite of no work experience.
Good luck with your search for the trainee position.
