Just a few thoughts subject to location and day. 1) Regardless of location, you could ask one of the local bullion dealers to support the gathering via both attendance by a local bullion dealer to spruik their products in return for some discounted items for sale and maybe a few giveaways. 2) If held in Sydney (on a weekday), ABC's refinery is located in Marrickville (inner west suburbs of Sydney 15 mins from CBD). Could always approach them about a refinery tour for the SS members. 3) Maybe a bullion dealer (if held in a major city) could provide a room for the meet.
