While the Blues and Maroons have three weeks until their series decider, Deadly Choices are getting into the Origin spirit with some greats of the game encouraging others to take action now during Men's Health Week.

Ahead of Wednesday's blockbuster at the MCG, Dean Widders, former Blues star Timana Tahu and veteran referee Gavid Badger teamed up with the Victorian Aboriginal Health Service (VAHS) for a morning tea and clinic in Fitzroy.

Deadly Origin health check winners were brought along to the Blues' captains training run session earlier in the week.

Tuesday saw series winners for Queensland Scott Prince and Petro Civoniceva at the Institute for Urban Indigenous Health in Magandjin / Brisbane encouraging Aboriginal and Torres Strait Islander men to get their 715 Health Checks.

715 Health Checks are free, comprehensive annual health assessments for First Nations people.

The checks are designed to identify risk of illness and chronic conditions.

Community-controlled health servies, as well as mainstream health services, across the country are able to provide the checks.

In Magandjib / Brisbane, Deadly Choices ambassadors Prince and Civoniceva were joined by Federal Special Envoy for Men's Health Dan Repacholi.

"Deadly Choices works because it empowers Aboriginal and Torres Strait Islander men to prioritise their health," Deadly Choices' Corey Kirk said.

"It makes health practical, positive and culturally strong.

"Through sport, ambassadors, community events, health campaigns, education programs and the well-known Deadly Choices health check shirts, it gives men a reason to walk through the door of their local Aboriginal Community Controlled Health Service and stay connected.

"Deadly Choices helps break that pattern by making preventative health normal, visible and something to be proud of."

The preventative health program partners with dozens of sporting organisations, NRL and AFL clubs in spreading their healthy choices message.

Community-grounded and ACCHO-partnered health care works, and critically provides trusted support, Mr Repacholi said.

"Origin gets everyone fired up, but this week we want Indigenous men to bring that same energy to their health," he said.

"Too many men put their health last. They push through, put it off, or tell themselves they will get around to it later."

Getting your health checked is not a weakness, it's a strength, Mr Repacholi added.

Mens Health Week runs June 15 to June 21.
