Hi, I want to open a restaurant, so how can I buy the equipment in Oz?

PS. Quality and cheap

Go to restaurants in your area. Ask who their equipment supplier is.

Check the big city newspapers (or online) for commercial auctions. Restaurants fail frequently, and you can get good deals at auction.
(Have the required codes for your area first of course.)

PS. Quality and cheap

For commercial equipment, these 2 words don't usually go together.

Check the main city market and online,you must consult the equipment supplier.
