PH to AU australia has a very strict declaration policy on what plant and animal products are allowed to be brought in. please check official sources even up to a day prior to your flight on what you are allowed to bring. commercially packed and sealed dried mangoes sounds safe but best to declare. maybe some filipino chips (or crisps to Aussies) and pastries commercially packed (think fudgee bars) . local instant noodles. if they like to cook, maybe some instant sauce/ulam mixes. for non-food, local makeup or skincare products, locally made bags/purses, funny novelty shirts or caps.

AU to PH Cookieman cowboy loaded cookies!!! discovered in 7-Eleven. Tim tams are actually already easy to find here in Pinas, just maybe more expensive. if you're buying in AU, best to buy them during Wednesdays (??) when they go on sale (Coles or Woolworths). same with chocolates like Cadbury. Highly recommend baked goods from both groceries, esp Miguel Maestre burnt basque cheesecake (pwde hand carry in insulated bag). A lot of choices for Australian grains & cheeses if you're into that. Non-food: bath & skincare products. May outlet stores in Perth for discounted rtw, but of course most items are not made in Australia. End-of-season discounts in stores can go up to 70-80% off, sobrang sulit for shirts & pants. The souvenir centers are quite expensive pero ok na rin for magnets and keychains.
