@mau_villa I agree with @Hunter_08 na magdala ng clothes kasi mahal ang in season clothes. I suggest na magdala ka rin ng clothes na pang-interview para hindi mo na iisipin ang paghahanap nito. Depende rin kasi sa height mo, some clothes might need to be altered such as shortening of pants, so mas maigi nang may magagamit agad.
AU$10k++ sounds about right. Ang biggest expense ay ang rent so I would suggest that you check online kung magkano in the area you will move to para may idea magkano kailangan i-budget for this. If you will immediately rent a house or flat kailangan din magbudget para sa bond, which is paid upfront on top of about 2 weeks advance rent.
If you haven't done this yet, you may want to open an AU bank account while you are still there para pagdating dito kukunin mo na lang yung card sa branch. Pwede ka rin kasi magtransfer ng money sa AU account mo while still in the PH.
