Basic things to bring in brissy:
clothes (I think), pure foods corned beef, nestea ice tea, goldilocks polvoron, nbi clearance (kesa pumunta pa ng sydney), pictures yung pang ID (white background) passport or 2x2, 1x1.
Things that are cheaper here because of price match, tawad, 2 yr aus warranty, easy to return/exchange, online stores, factory outlet sa GC, discount vouchers/coupons, cashrewards, birthday freebies, reject shop/dollar store, then parang every 2 months may sale ang ebay:
clothes/shoes (if you know your size and brand then shop online na lang), electronics, computers, games (electronic except steam [mas mura steam sa pinas pero geolock] or physical -badminton, swimming etc), food/grocery. Mas mura din ata kuryente dito sa brissy (not sure sa ibang states) kumpara sa manila, pwde ka pang humingi ng discount sa provider like origin or 1 switch or something.
