The next year, she competed in both the junior and senior USSR Championships, winning the all-around silver medal at the former and finishing fourth at the latter, and was selected as the alternate for the Soviet team at the 1984 Friendship Games (also known as 'Olomouc', after the city in which the competition was held).

She also competed at the European Championships for the first time, winning the balance beam title showing a triple twist dismount.

However, Soviet team officials decided to pull Olga Mostepanova and Irina Baraksanova, who had both qualified for the finals, and substitute Omelianchik and her teammate Shushunova.

She also showcased a new floor routine to Ballet Russe and a new triple full to a tuck front rebound, but suffered an uncharacteristic fall in the team competition.
