The only defeat England have suffered in the past five years was the 2022 World Cup final against New Zealand.
But the Red Roses are unbeaten since Packer took on the captaincy during the 2023 Six Nations – something she is proud of and believes will continue.
“Since I’ve been captain we’ve not lost a game, so I’ll have that one at the moment,” she said.
“You’ve got five games in the Six Nations, you’ll have a couple of warm-up games and then you’ll have the World Cup.
“So you’re looking around that 30 mark again to whether we can win that World Cup final, which in my head it’s a definite ‘yes’.
“We just need to make sure we work really hard as a group and keep inspiring each other, and remembering why we are the best in the world is because we push each other to be the best.”
