Monthly flea market in a hired hall or oval

Stallholders pay a site fee to sell. Shoppers usually get in free or for a gold coin donation. Local cafes or food vans may pay a fee to trade on the day.

Stall fees per site (for example per table or per 3m space) minus venue hire, insurance and advertising. Extra income can come from food vendor fees and sponsors.

Check public liability insurance and whether stallholders need their own cover. Also check council approval or a temporary event permit, food seller registration with councils, your state's second-hand dealer rules, and ABN and GST requirements as turnover grows.
