Disclaimed property

So the liquidators have made an announcement that they don't think the proceeds realised from the sale of certain assets will cover the selling costs involved. Fair enough, but what happens to these assets now? The intangible assets (mining leases) will just lapse, but the physical assets? One is a block of land in Chinchilla - who gets that if it's not sold?
The other physical assets can be taken to the tip if they're not worth selling, but how do you dump a block of land? It's this asset that I'm most curious about.
Any insights welcome.
