I find that hard to believe, which area are you in? I have a list I normally give to friends visiting, I'll pare it down to some of the best Asian options though
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
