How can I learn German?

Ok, so I am 15 and I have moved around a lot. I lived in England for 11 years in primary and middle school, Moved to Australia - QLD for 2 years for primary and high, finally i moved to NSW in 2009. ive been in 3 schools, just moved to a new one 2 weeks ago. well anyway, in my high school in QLD i learned a little German but i really loved it! it was my favourite subject. the days i had German were my favourit days. So i havent spoken any for about 2 years now. I REALLY want to get back into it! so is there any clubs to go to or online lessons?! ANYTHING that will help me learn German. but if it is on the internet then i cant pay for it. thanks
