Staff at Heston Blumenthal's Crown Casino eatery Dinner by Heston face an uncertain Christmas and New Year period after the high-end eatery appointed provisional liquidators, raising questions about how it will fulfil its obligations to staff and suppliers.

The business, which has been beset with allegations of staff underpayment, has until January 3 to inform employee-creditors that provisional liquidators have been appointed to the business.

It is unclear how much staff and other creditors are owed as provisional liquidators were appointed on late Friday and are still assessing the financials. Under Australian law, employees are treated as priority creditors in a liquidation and the government can pay for some unpaid entitlements if the business does not have the capacity to do so.

On Friday, Brian Silvia and David Coyne of BRI Ferrier were appointed to Tipsy Cake Pty Ltd, the owner of the restaurant which The Sunday Age and Sun-Herald revealed last year is incorporated through the Caribbean Island of Nevis.
