The 23-year-old from Kellyville hopes to win his battles with the state's best fighters to gain a place in the national competition next month.

``If I can win at state I need to win first or second place at the nationals to get a scholarship with the AIS [Australian Institute of Sport] and hopefully after that get to the Commonwealth Games. That's the plan anyway,'' Colosimo said.

The Commonwealth Games Colosimo's ultimate goal is held in New Delhi in India in October.

``If I don't make the Commonwealth Games I will probably turn pro as I am amateur at the moment,'' he said.

Colosimo has been riddled with injuries he's been out of the boxing circuit for the last few years but is now fighting fit.

``I actually made the finals for NSW for the last Commonwealth Games but I was forced to pull out of the trials as I was injured,'' he said. ``This time is all the way. I feel good and I am ready to fight.

``I have just come back from the AIS from a two-week training camp.''

Colosimo will compete in this weekend's event at junior welterweight 64kg, which is the most contested division in Australia.

At 17, Colosimo had his first fight and first win.

``I started boxing as I had five older brothers who were into it and I wanted to beat them,'' he said. ``I was lucky enough to get to train with Jeff Fenech's trainer and he told me I had what it takes.''

Colosimo, who trains at Bulldog Gym, Castle Hill and Castle Hill Self Defence Centre, has fought and beaten top Australian boxers including the Arafura Games champion in a tournament which involves seven countries with competitors from Scotland, New Zealand and Malaysia.

The round robin tournament this weekend will be held at St George PCYC, Rockdale.

It starts on Friday night and the final will be contested on Sunday afternoon.
