Jessica Carr-Walker and husband Greg have never felt more satisfied after tucking into a meal at Under Wraps in Macrossan Street.

And why wouldn't they? It's not everyday a sandwich wins you flights and eight nights in Hong Kong.

"We've never won anything before," said Greg, who moved to Port Douglas with Jessica one year ago.

Jessica may not have been to Hong Kong previously, but there are family connections with the towering city with her Mother-In-Law born and raised in Hong Kong.

The competition, which was a collaboration between Under Wraps, Jetset Travel (conveniently located two doors down) and Air Niugini, has been running for the past three months with 2,800 entries received from locals and visitors from all over the world.

Under Wraps' Wayne Stapleton said the response was so great the partners have decided to run a competition every quarter, with the next one kicking off on 1 September and drawn on 21 December.

"We'll either be offering a travel voucher or another overseas holiday which will be a great Christmas present for the lucky winner." Wayne said.
