Before upwards of 90,000 fans pack the stands on a sold out Boxing Day in the upcoming Ashes, some of the country's best First Nations cricket talent have walked out on the MCG to showcase their talents.

National Indigenous Development Squad men's and women's teams faced the Melbourne Cricket Club (MCC) at the ground on Thursday.

The women's Indigenous XI weren't able to repeat their efforts from last year, where they comprehensively beat the MCC XI by nine wickets.

Still, any opportunity to play on the 'G is one to savour, Maddison Spence, judged the First Nations team's best afield, told National Indigenous Times.

In an innings where wickets were shared evenly Spence was tidy with the ball, ending with 1/15 from her four overs to help keep the MCC to 7/113.

It's a "once in a lifetime" kind of experience to play on the ground, Spence said, with hopes to add a few more in coming years.

Thursday's games came via the annual National Indigenous Cricket Training Camp, bringing establishing and emerging Indigenous high-performance cricketers to Naarm for a week of exposure to elite pathways to further hone their skills.

Earlier this week, Cricket Australia and the MCC Foundation, who deliver the camp, announced its extension for a further three years.

"It's been awesome. Everyone has gelled from the start," Spence said.

"It feels good (named her side's best on ground), bowled pretty well, so to have it recognised is pretty good.

"Hopefully (I'm back) for the next three years with the extension."

The Indigenous XI got off to the perfect start when Callee Black found the edge of MCC's opener, caught at slip by Dharmini Chauhan in the first over.

Aimee Ravot had her side's second making it 2/37 after Kamya Mishra (20) and top scorer Rhiann O'Donnell (36) started to build the home side's innings.

Amelie O'Meara added 23 runs for MCC before being removed stumped from Carys Underwood's bowling.

Mahlie Bennett and Chauhan had a wicket each to join Black, Ravot, Spence and Underwood.

Requiring 114 for a win, the Indigenous XI's innings never really got going.

Chauhan and Charlotte Toohey (14 runs) started their partnership by rotating the strike, but a strong showing from MCC's attack combined with scoreboard pressure limited the middle order's influence.

Six wickets down and needing 74, Merinda Hale and Grace Abdy put together a stand in excess of 30 runs.

Back-to-back boundaries form Hale, who scored a run-a-ball 24, made the 46 required from the remaining six overs look getable before she was removed, caught, when Rhiann O'Donnell held on to a fast-moving ball at mid-wicket.

The Indigenous XI were eventually bowled out for 81.

Limmy Thilakarathna and Darcy Collins led the MCC with two wickets each.

"To have it locked in for the next three years is really special," O'Donnell said of the annual contest with the National Indigenous Development Squad.

"It's definitely a significant day for us in the calendar."

In the men's contest, three late wickets from Taungurung spinner Bailey Toseland helped restrict the MCC to 118.

In reply, the Indigenous XI got off to a quick start before an injury saw the match abandoned.

Post-play, Development Squad squad coaching staff and Cricket Australia National Aboriginal and Torres Strait Islander advisory group member, Guy Grey, told the playing groups the day and camp is "true reconciliation, closing the gap...in cricket".

"The fire burns in our belly, as First Nation people, for being able to play here," he said.
