Seems to be a reasonable size auction in NSW opening next week. Must be a closed mower shop or similar. Lots of service items, mowers old and new and other workshop related items.
Here is a list of all items: https://www.pickles.com.au/general/item/search#!/search-result?q=(And.ProductType.General%20Goods._.(C.State.NSW._.City.Queanbeyan%20West.))
There is also a box of the notoriously hard to find Victa 18 wheels (not new - used), but can't see them in the list at the moment - they were one of the last lots.
