我想去澳洲讀英文, 究竟有冇用GA?

半年太短, 只可以講有進步, 唔會太叻,
但都要睇你讀邊種學校, 如果間學校多中國人, 就多數用廣東話和國語講野, 即係冇咩用.
如果間學校多其他國家既人(除左中國, 馬來西亞..會講國語既地方), 會比較好. 因為可以從講野中學到英文~~~

It depends on the course provider. It's better not to study in city area as there are too many Cantonese and Mandarin speakers within city area. And if you really decide to study here aiming to learn English, I suggest you to stay with home stay and not to hang around with Asian friends. Sydney and Melbourne are definately not recommended, go some country side places in Perth, Adelaide ...
