Next week the Carthage Street operation will start their annual $5 bag sale, while any items not sold will be packed up and shipped to Africa via the One Ten Enterprises organisation.

In 2018 alone St John's sent 25 tonnes of excess clothing to Kenya, Madagascar and Mozambique, with the organisation turning that simple act into a win-win-win according to Op Shop manager Carol Brice.

"It is a great initiative where everyone benefits," she said.

"Instead of going to landfill those clothes get sent to Africa, where some are given to communities in need, while others go to merchants to sell and create business."

Cyclone Idai hit southern Africa last week, leaving a trail of destruction including a growing list of 750 casualties, as well as 110,000 people left without shelter.

Ms Brice said having the Op Shop and donations bins in the heart of East Tamworth plays a key role to not only the sheer quantity of clothing donated, but also the quality.

"We are very lucky to be situated here - we have to empty the bins twice a day sometimes," Ms Brice said.

"We have got a great team of volunteers that come in and sort the clothes, and have a good time." 

The $5 bag sale starts on April 1, with one shopping bag, on average, fitting up to 20 items of children's clothing or four pairs of adult jeans, and everything in between.

The St John's Op Shop, and Op Shed, are open Monday to Wednesday from 9-12.30pm.
