well maradona its a hard one .... they have stated their minimum requirements are fluency in the advertised langauages. If you go, they will register you... then tell you are unsucessful... then you cant apply again for six months.
But knowing QF, they might re-advetise in a few months time without the lannguage requirement ( QF hasnt advertised the language thing for a while)..... then you cant apply again !!
Its a tough choice, I wouldnt apply this time round if I were you... we have already said we are going to start to fly to south america early next year again.
Your choice though
