Poland is represented by Sara Dragan, Zofia Anna Olesik and Wojciech Niedziółka, who will open second-stage auditions on Tuesday.
Niedziółka is taking part in the Wieniawski Competition for the second time. Four years ago, he was the best Polish contestant but failed to qualify for the finals.
In the second stage, the participants will perform a recital lasting from 45 to 50 minutes and consisting of a sonata for violin and piano and shorter pieces of their free choice.
The prizewinners will be announced on October 22.
The first-prize winner will receive EUR 60,000, along with a range of career-development opportunities. Many special prizes will also be awarded, as well as the audience prize.
The 10-member international jury is chaired by Polish violinist Bartłomiej Nizioł, who won the 1991 Wieniawski Competition.
The Wieniawski Competition is the world's oldest international violin competition, according to its organisers.
It was first held in Warsaw in 1935 and moved to Poznań after a 17-year hiatus. It has been held in Poznań since 1952, usually every five years.
Past winners have included David and Igor Oistrakh, Ida Haendel, Ginette Neveu, Agata Szymczewska and Veriko Tchumburidze.
Henryk Wieniawski, the Polish virtuoso after whom the competition is named, was a child prodigy who entered the Paris Conservatory at age 8.
He is widely regarded as one of the greatest violinists of the 19th century after Niccolò Paganini. He died in 1880 at the age of 45.
