Taste test at Crab Fest

WA's biggest seafood extravaganza will draw more than 120,000 people to Mandurah at the weekend for the town's annual Channel 7 Crab Fest.

In its 15th year, the event offers wide entertainment including live music, food stalls and kids' activities on Mandjar Bay.

Mandurah mayor Paddi Creevey encouraged people to take the train from Perth.

The festival will have high-profile entertainers, including former Australian Idol contestant Shannon Noll and Cold Chisel guitarist Ian Moss.

It will also have a fashion show by local designers and family activities, including a Constable Care dance party and Elmo and Friends.

The International Waterski and Wakeboard Federation World Cup should thrill the older crowd.

But the highlight for many will be the abundance of crab-themed food.

Six contestants from hit TV show My Kitchen Rules will also show the best ways to cook the delicate meat.

WA mother-daughter team Lisa and Candice Clarke said they looked forward to putting on a show. "We both teach south of the river and a lot of our students will be there," Lisa said.
