Singaporean in Sydney here -- I've barely found any decent Asian food in my time here, not to mention the exorbitant prices. Could you recommend some options? I'll love to improve my food options here.
Sydney is generally cheaper than Singapore in my opinion. What you get for $2.50 at a hawker centre is absolute junk. Ingredients have costs, and most of it is imported from AU anyway. Any price advantage you see in SIN usually means skimping on ingredients compared to what you would see in SYD.
Dumplings - Chinatown Noodle King (also ridiculously cheap, order the Fried & Spicy Pork & Chive ones), Ramen - Ryo's, Thai - Khao Pla (used to be amazing, not so sure about the quality now), Viet - Hello Auntie, Banh Mi - anywhere in Cabramatta, Izakaya - Yakitori Yurripi
