Blackwell, regarded as one of the world's best players, said the new junior formats - and the rapid growth of girls' participation in cricket - had provided children with opportunities that weren't available to previous generations.

The former Australian captain said what had amazed her most about the overhaul that's been designed to increase each player's level of participation is they're "so simple".

The junior formats have been tailored for young cricketers aged between 9-12 by reducing the length of the pitch; shortening the boundaries; having less fielders and guaranteeing each player the opportunity to bat and bowl

Australian cricket rolled out the new junior formats for the 2017-18 summer after last year's nationwide pilot provided data which proved the shorter pitch resulted in more balls in play because bowlers could more easily reach the other end of the pitch, and that meant more wickets were taken per over and more runs were scored per ball.

"It was such a simple shift to make," said Blackwell.  "It makes sense that the size of the ground, and the length of the pitch, needs to be matched to the size and ability of the people playing the sport.

"We're already finding out these changes have created a much higher quality of game for the parents of the players to watch, but it's exciting to think boys and girls are not only having a much more enjoyable playing experience, but their skills are developing quicker because the [changes allow children] to bowl at the right length and at a trajectory that enhances the batter's ability and skill.

"I think everyone needs to embrace the roll out of the junior formats because it's a simple change that has been made after a lot of research."

Cricket Australia's Junior Formats Manager, Harry Tinney, said there had been a tremendous take up of the formats by junior associations around the nation.

"We've had 160 Associations out of 247 (nationally) adopt Stage 1 of the new junior formats and the feedback is that kids are loving it," he said.

Blackwell was as enthusiastic about the raid growth of girls' cricket, pointing out that a recent presentation made by Cricket NSW chief executive Andrew Jones highlighted how far it had come since she and her twin sister Kate, a fellow Aussie representative, played against boys in the country.

"Andrew recalled that not so long ago there was only two girl's competitions in Sydney – one on the north side and one in the south – but we now have 300 junior girls' teams and that's been linked to the Thunder and Sixers' cricket leagues."
