A collection of some of Australia's greatest wines worth an estimated five million dollars has gone missing in the country.

Police in the Hunter region have appealed to the public for information after failing to find the A$5m stash of missing Australian wines.

Full details of the wines were not released, but police said the haul was made up of dozens of individual wine collections.

Bottles include some of Australia’s best-known wine names, such as Penfolds Grange and Henschke.

Police said the wines were being held by Wine Investment Services Pty Ltd until 2013, when the firm collapsed into receivership.

Some of the firm’s assets were seized, but ‘inquiries revealed a number of wine collections were not surrendered’, police said.

In March 2016, detectives from the State Crime Command’s Fraud and Cybercrime Squad launched an operation named ‘Strike Force Farrington’ to investigate the missing wine.

Officers raided a warehouse in Newcastle on 31 May and seized documents and electronic devices, police said.

‘As investigations continue, detectives are appealing for assistance from the public to locate the wine collections.’

Police added, ‘In particular, they would like to speak with anyone who may have purchased, or has been approached to purchase, collectable or vintage wines, including Penfolds Grange, varieties of Henschke, Torbreck, and Chris Ringland/Three Rivers.’
