Kung wala kang cert 3 or 4, typically kapag 2nd or 3rd year na mga BN cinoconsider nila for a job as PCA. It is the prerogative of the manager o company rules. At kung may nagapply na may cert 3 at nagplacement sa kanila bakit hindi nila kukunin yun di ba?
Medyo malaking gamble yung wala kang initial funds tapos tingin mo makakahahanap ng work within the first 3-6 months. Kung hindi ka magtiyatiyaga within the first 3-6 months usually hindi lalapit yung work sa iyo.
I'm not discouraging you pero meron talagang nagco-course to course. Paminsan yun feeling ko sapat lang yung inipon para sa next tuition at student visa application. Meron din naman na nakakayanan from aged care to enrolled nursing to registered nurse. O from aged care straight to nursing.
Make sure you factor in work, expenses, nursing requirements and visas para sa goal mo.
