Just to include to the tips mentioned above. Since ang prinoproblema ng halos lahat ng migrants when looking for a job is local experience, it is advised that all overseas references are taken out from the CV or Cover Letter. In the Cover Letter, discuss your skills and experiences that match the employer requirements. Huwag na banggitin kung saang bansa mo ginawa ang work. Then on the first page of the CV, just highlight your skills and characteristics that is required for the job. For work experience, just put the name of the Company, date you worked there, and a brief summary of work performed. Again Sa summary dapat closely related or exacto dun sa job description ng advertised job. There is no need to put the country where your previous company was located!
For references, it is advised that these should be located in AU. If this is not possible, just leave it out. They will ask for it once your application is successful.
It's also advised for those with foreign sounding names to tweak your name into a more Aussie friendly name. This will make it easier for your prospective company. Take note that your CV is not a legal document that requires your full, legal name. Even Aussies tweak their name as and when necessary.
Lastly, roads in the Phil, Singapore, Saudi, Australia are all the same. There are only differences in safety and regulatory requirements. Same is true for accountants, MYOB, JD Edwards, Etc are the same all over the world kaya there is no reason why your overseas skills are not transferable to AU.
Cheers!
