Illawarra is at the top of the Australian karate pecking order following a double success at the national full contact karate titles in Sutherland.
Fighting out of Illawarra Kyokushin Martial Arts Gymnasium, Unanderra's Viktor Timev took out the heavyweight division in the round-robin tournament while Shellharbour's Daniel Capetta proved a surprise packet in taking out the lightweight division.
"It's unprecedented for Illawarra fighters to take out two of the top three divisions," coach Jason Baltov said.
"We almost took out all three divisions with one of our fighters [Leon Theofanou] narrowly being defeated in the final."
Tournaments are held in a round-robin format often decided by a single three-minute round.
"In most cases the first round ends with a knockout or a judge's decision," Baltov said.
"But sometimes if the judges cannot decide who won the round, they'll make them fight again so fights can go for several rounds."
Timev was impressive in the heavyweight division, winning five bouts including a victory over highly fancied wildcard New Caledonian fighter Jean Louis Rungi.
"He [Timev] doesn't have a whole lot of experience but on what he showed at those titles he's going to be a very, very good competitor."
Capetta was the underdog in his first bout against a far more experienced New Zealand competitor but came up trumps with a victory, propelling him to four more wins and the national title.
"I think he even surprised himself," Baltov said.
Promising Wollongong middleweight Leon Theofanou was heavily tipped to take out the middleweight title but was narrowly defeated in the final by Sydney rival Jesse Connolly.
The gymnasium also got a welcome look into the future in 14-year-old Figtree fighter Lachlan Milne, who was runner-up in his division.
