Australia's emerging generation of top-class Indigenous cricket will have ongoing opportunities to develop their talents at the MCG for another three years, with the extension of an "enormously important" piece of the summer calendar.

For the previous three years, men's and women's national Indigenous developments squads have come to Naarm for a week-long engagement in elite performance circles.

Cricket Australia and foundation arm of Melbourne Cricket Club (MCC), who deliver the camp, announced its continuation for a further three years on Tuesday.

"Cricket's connection with our First Nations people is really well documented. A key moment started back in 1866 when an Indigenous team actually played the MCC on Boxing Day here at this ground," Cricket Australia chief of cricket James Allsop said.

"On Thursday, and some 157 years later, we'll once again see the MCC host CA's Indigenous men's and women's teams in T20 fixtures.

"The National Indigenous Cricket Championships and the National Indigenous Training Camp here at the MCG are enormously important events for Australian cricket.

"We want to significantly strengthen the connection between Aboriginal Torres Strait Islander cricketers into our pathways and elite teams, and that really is the cornerstone of the evolution of this partnership."

Allsop added the camp will play a "pivotal role" in the next generation of Indigenous cricketers.

MCC Foundation chair Christian Johnson added: "We believe this initiative provides great opportunity for First Nations cricketers to develop their skills and pursue their goals, to play at the highest level that they can possibly play."

27 players from across the country are on Wurundjeri Country for the opportunity, some returning for another camp after previous attendance.

Kaurareg spinner Clodagh Ryall was due to take part before being selected in Brisbane Heat's T20 Spring Challenge Series squad off the back of impressing with Wynnum-Manly in Queensland's recent T20 Max competition.

Ryall has previous experience in pre-season games for Queensland Fire, and featured for the state in April's National Indigenous Cricket Championships.

Veronica Keen and Brock Larance will captain the two Indigenous sides on Thursday.

"It's the best place to play cricket in Australia, maybe even the world," Keen told National Indigenous Times.

"Getting to come here is really, really special. There's a couple of young girls...it's their first time out here. I think they'll really enjoy it.

"I know for me, it's always such a special opportunity. For all the girls coming back we really value being able to be around the MCG and play on it."

Keen and Larance said there's genuine talent in the group.

Larance said they carry some responsibility in fostering the next generation's being able to enjoy the same chance.

"What we do now, and how the MCC looks after us... if we don't do this well and put our best foot forward then they're not going to get that opportunity. It's about taking in as much as you can and giving as much as you can back, and learning as much as you can so we can pass stuff on to the next generation and keep producing this sort of talent," he said.

Test quick Scott Boland was in attendance at the announcement.

"I don't think there's really any better place in the world where you want to be plying your trade...I think it's a really good opportunity for them, and hopefully it's a stepping stone for more Indigenous creators to come through and to play for Australia in the coming few years, Boland said.

Men's Indigenous squad coach Jeff Cook is a former captain of NSW's Indigenous side and First Class cricketer in England.

He said it's important seeing every state and territory represented at the camp.

16-year-old quick Harrison Johnny is the first member of the camp out of the NT.

"I think it sends a message that wherever you're from, whatever country town you're from, there's still opportunity in this program for First Nations cricketers," Cook said.

"All the players are just they've got a buzz about them. They're on the MCG, they've worked with (former Test bowler and Gamilaroi man) Jason Gillespie this morning. Scott (Boland) is here this afternoon. There's a bit of a bit of a buzz around for these young guys, which is what it's all about."
