The Pacek's Shotokan Karate Academy junior showed tremendous speed, power and excellent technique to claim the gold medal in the 11-12 years advanced female kumite event in Sydney.

Brittany backed up in the 11-12 years advanced kata division to claim a silver medal after losing narrowly in a competitive final.

Brittany has been fine-tuning her kata technique in the past few weeks for the national championships in Perth, Western Australia, on August 1-3.

The young champion will represent NSW alongside Pacek's Academy students Adrian Furina and Elyse Wood.

All three are to compete in kata and kumite divisions, plus the team kata event.

After competing in the national titles, Brittany will represent Australia at the 16th Oceania Karate Championships in Suva, Fiji, on September 12-13, taking on some of the best young karate exponents in Oceania.

Brittany, Elyse and Adrian train twice a week at Tahmoor Public School.
