WA's only mobile butcher has completed his last outback trip for the year, making record Christmas sales on the marathon journey.

Once a month, Perth-based butcher Larry Brewer stocks his specially designed semi-trailer and embarks on a tour of the state's north.

He and his team cover 4,500 kilometres per trip, supplying meat to six Pilbara towns, none of which have an independent butcher.

Mr Brewer said it was an unusual lifestyle but he could not be happier.

"I love it, I just love it," he said.

"We leave Perth on a Sunday night, fill up a couple of tanks and have a nice roast for tea, then off we go.

"It's very unique, and probably the first of its kind in Australia, in terms of being such a walk-on mobile shop."

The butcher, who sold his Perth store to fund the venture, makes a point of avoiding towns where there is an independent butcher operating.

But he is happy to offer a service to rival supermarkets chains such as Coles and Woolworths.

Stop-offs are made in Newman, Tom Price, Onslow, Karratha, Wickham and Port Hedland, in an eight-day trip that requires precision timing.

Mr Brewer also makes a stop on the highway turn-off to Parabardoo, where residents drive out to meet him by the roadside.

"It is unusual - we get a lot of European tourists who are just fascinated by what we're doing, and the service we're offering in the these remote places," he said.

Travelling butcher avoids high regional rents

Australian Meat Industry Council WA representative Mike Thompson said Mr Brewer's unconventional business was viable because high operating costs in mining towns had driven out many small, independent operators.

He said the service the mobile butcher provided was important for regional residents.

"I think it's fantastic because if you look at it, the north-west of WA has been disadvantaged forever really, because of the distances," he said.

"Fresh produce to get up there is very difficult and expensive, and it's often hit and miss in terms of its quality."

Mr Brewer's truck trailer has been converted into a shop, complete with fridges displaying cold cuts and a cash register.

"I decided to go all-out and get it converted into a walk-on shop, so that people actually walk up into the truck trailer to get them out of the elements, away from the flies and dust and heat," he said.

"It's a bit more relaxing, like they're walking into a real butcher store."

The business started two and a half years ago, and Mr Brewer said sales had increased over the Christmas period.

"We started from nothing, so we're quite proud now of the customer base we've got," he said.
