Agree with @batman I also maintain an account in PH for my PH txns. Make sure that you update first your mobile numbers in your PH bank para when you do fund transfers, you still get the OTP in your AU number. AFAIK, walang charge yun.
@barbedwire in my case, I used my trusted friend's AU address for my bank account so lahat ng mails ko napupunta sa kanya. sealed naman yun so you would know if your friend is really trusted or not :-P Make sure lang to update all systems pag may perm address ka na. For medicare, centrelink and TFN, I think you have to be in AU to process that. May personal appearance sa medicare (including your family if you have one) and TFN naman knows if you are in AU already even if processing is done online.
@beetle00 uber does not accept cash so dapat may card ka 🙂 cabs accepts both cash or card.
@PinoyMech I wouldnt risk bringing in my pirated software/media. I read somewhere that they can now open your laptops, even your social media so I would rather put it in a cloud drive instead (ie, google drive, dropbox). But then again, its still your decision 🙂
