The 23-year-old from Kellyville hopes 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,'' Colosimo said.

The Commonwealth Games Colosimo's ultimate goal are being held in New Delhi, 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.

Injuries have kept Colosimo out of the ring for the last few years but now he's 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 it's all the way.

``I feel good and I am ready to fight.''

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

``I am pretty pumped,'' he said.

``I have sacrificed a lot for the fights this weekend.

``A lot of early mornings, blood and sweat have gone into my preparation so I am hoping it all pays off.''

Colosimo had his first fight and first win at 17.

``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.

``Boxing is a sport I really enjoy.

``You are always testing yourself and challenging yourself to be better. I like that.''

Colosimo trains at Bulldog Gym, Castle Hill and Castle Hill Self Defence Centre.

This weekend's round robin tournament will be at St George PCYC, Rockdale.

It starts on Friday night with the final on Sunday afternoon.
