Planning to study abroad

Hi, I am a Grade 12 graduate student po and already enrolled na din po ako sa college (program BSN) somewhere here in ph. I’ve been thinking about how I’m gonna be able to study abroad, I'm thinking of studying in Australia or USA next year to study as a first-year student again, Does anybody have any tips or any steps on paano po makakaapply. Also, may recommended po ba kayo na Universities na pwedeng maapplyan ko and please also provide the tuition fees if ever. Thanks!
