I know this is common in some countries within Asia, where you see street vendors selling snacks for a cheap price (as in they’ve made the products they’re now selling from home, being handed out to potential customers who buy them), managing to generate revenue, at least they can start a business somewhere even it’s slow at the beginning. Try and do something similar in AU: gets shut down the moment it appears.
This is not the same as food trucks per say, rather the vendor is setting up a table displaying the food made at home ready to sell onto people passing by hoping they’ll purchase them. As in, would it work if you’re selling a snack that’s ~A$5 on the street while a similar thing is A$20 in an establishment (cash only payments) at the busiest cities (Melbourne or Sydney) in the same manner on how it’s done in let’s say Thailand.
I think, to my knowledge is neighborhood density and urban planning: as in Asian countries tend to have room on accommodating spaces to set up stalls (operating on an informal economy with cash only payment or QR code via a third party payment app) and residences are adjacent to cities traditionally supporting high foot traffic and dense pedestrian transit meaning you’ll likely have people buying the stuff you’re selling.
Don’t know about Australia, but in Japan, you need a food safety license to sell cooked food, and additionally, it must be prepared in a kitchen that is not your residential one.
