Dive and Dive Melbourne Victoria Australia, hope it helps. o by the way the course is designed for people at an intermediate level, the guy there told me i should b able ot sit comfotably on the bottom at a level of 10 meters before signing up. i never botherd tho cos the places were i go spearfishing are only about 10 meters anyway, but im considering it just to improve my techinque. have fun
