A little advice about oz please
 

I need some advice please. I have recently met a girl on the net from oz she has come over to the uk to meet me and stay with me for a few months, she is going home now though because she dosent like it over here. anywayz i am due to go over in Feb I have been told to get a working holiday visa ( thankyou to all the people who advised me to do this on this site) i was just wondering how easy it is to get a working holiday visa to go to australia and the chances of me getting turned down and also whether it would be possible to go over on a normal 3 month visa and apply for a working holiday visa while im over there. also a friend told me the other day that australia has an amnesty every 5 years or something and if you apply for citizenship on the year of the amnesty you get it. is this true and if so when is the next amnesty??? Also one more thing to move to oz and be with my g/f i have been told to go for a defacto visa now what would the chances of me getting one be and what sort of things do they look for if I was to apply for one of these. May i just say that I am in £7000 worth of debt in this country and would it affect me in any way at all if I was to move to Oz on the defacto Visa or whatever. I would be grateful for any help thankyou very much.
