If you want to work in Au as a Nurse you have to study first. There are upcoming changes on the second half of the year and the Bridging program might be abolished. I agree with the post above, if you want to work here in Au, you have to gain the required years of experience first as a Nurse para counted siya for the skills assessment. Kapag may experience ka na as RN, maraming opportunities and countries ang open for you.
Kung kulang yung experience mo, pwede kang magconversion course. However, kahit na grumaduate ka rito as RN kung kulang yung points mo for migration it maybe hard for you to migrate and even harder to get a sponsorship if you lack years of work experience. Employers usually require applicants to at least have 3 years of experience for a sponsorship.
Yung financial aspect is another thing. Hindi maikakaila na mahal talaga rito and since ang pasok mo is student visa, limited lang ang work hours. Kailangan ready ka rin in this aspect. Don’t be disheartened though, keep on trying and applying. Work on your experience and save up until maging ready ka.
