More sixes have helped England become the world's best women's cricket team, but coach Mark Robinson says the boundaries should not be made longer.
His side hit four sixes in Sunday's Ashes-opening loss in Brisbane, while Australia managed three on an Allan Border Field with the ropes several metres in from where they would be in a men's game.
The ropes will be in again on Thursday night at Coffs Harbour International Stadium for the second game in the multi-format series, with the straight boundaries enticingly short.
That should favour world champions England, who have made a habit of hitting sixes after a massive shift in tactics since the last Ashes in 2015.
In one-day internationals between 2013 and the 2015 Ashes series, England managed just one six every 883 deliveries.
But since then, the team - with many of the same batters - have hit one every 133 balls.
In the same period, Australia went from hitting one six every 386 deliveries to one every 163.
Only one of the sixes hit on Sunday cleared the fence, highlighting the difference the ropes made.
But Robinson said the widespread increase in sixes showed how batters were developing to create a more-exciting product.
"I just think for the good of the women's game, it's a better spectacle," Robinson said.
"It allows the girls confidence to be able to swing and not over-hit.
"For the good of the game, the boundaries need to be the right size for women's cricket."
Australia possess some power hitters, with promoted opener Alyssa Healy and first drop Ellyse Perry two of the more-aggressive batters in the world.
Allrounder Ash Gardner also showed she could clear the ropes on Sunday, hitting two sixes in a whirlwind 18-ball innings.
"From a team point of view, we've prepared to be able to play on any type of boundary, from the maximum to shorter," the England coach said.
"Certain teams you might want them in, certain teams out, if you're thinking tactically. But we'll take what comes."
Defending Ashes champions Australia lead the series 2-0 with two more ODIs, one Test and three Twenty20 internationals to play.
Two points are awarded for a short-format win and Test draw, while four are given for a Test victory.
