This is the first time Australia has sent an under-19 women’s team overseas, and the first time the side has played in 15 years, having last played in a 2003 series against England.
Wareham played 11 games for the Renegades this season, capturing ten wickets along the way.
Coach Tim Coyle said the leg-spinner was the find of the competition for the club.
“It is great to see a young player grab her opportunity and get some big wickets and she was bowled at times in really tough game situations and she responded well,” he said.
“She sets a fantastic standard in the field and is just a naturally good fielder and she could become one of the best fielders in the world with work – so there’s a lot to like about her future in this game.”
Vlaeminck missed the Renegades campaign with a shoulder injury, but her selection highlights the regard she is held in by national selectors.
The 19 year old has also overcome two knee reconstructions.
Vlaeminck returned to the Victorian line-up in the Women’s National Cricket League a fortnight ago.
