International Mother Language day has been observed worldwide on 21 February every year since 2000, after it was approved by UNESCO, as a result of the initiative led by Bangladesh.
It is a day to celebrate linguistic diversity and to promote differences in culture and language to develop respect and tolerance for each other.
Dr Maria Staykova, immunologist at Australian National University - Canberra, presented Bulgarian poetry at the event.
