A NSW bride-to-be is devastated after losing her wedding deposit to Brisbane's Moda Events, which went into liquidation last week.

Muswellbrook resident Lana McGeachie, 26, and partner Clayton Davis became engaged in May 2017 and wanted to return to Brisbane to marry in her hometown.

NSW couple Clayton Davis and Lana McGeachie were going to have their perfect wedding at Moda Events until it went into liquidation.

She dreamed of a small wedding with 30 guests at Moda's portside venue in Hamilton because its small function room was "a perfect fit" for their budget and vision.

However, she received an email at 4.30pm on Tuesday from liquidators to say the venue had ceased operation and had terminated the contracts of 23 staff members after accumulating more than $400,000 in debt.
