Twenty inmates are part of the club, the only one in Australia that helps give men the speech skills and confidence to effectively communicate to others.

Toastmasters training will be beneficial for inmates upon release, Governor Brad Peebles said, especially when they're searching for employment, accessing services or applying for housing.

"Inmates often come into our care with a lack of education, general learning difficulties or with English being their second language," he said.

"It's been incredible to see inmates who once struggled with verbal communication and confidence, now speak for three-minutes with conviction and poise - it's quite remarkable.

"Being able to use your words effectively can be life changing."

The Toastmasters prison team operates much like those on the outside, having formal meetings and public speaking competitions on Friday night.

Inmates randomly select a card and are challenged to speak to a set time on a range of topics - think fairy tales, favourite foods and the values of leadership.

Toastmasters District 90 Director Monique Tonna said now the club has been officially chartered, the inmates can compete against other clubs outside of prison.

"Two inmates are competing in the area contest at the end of February," Ms Tonna said.

"They will participate over video-conferencing and enter three competitions. It's an exciting moment for Toastmasters and I hope their loved ones are really proud of what they have already achieved."

There are 785 Toastmasters clubs in Australia with more than a quarter of a million members around the world.
