Off the field has also been busy for Packer, with the vice-captain proposing to England team-mate Rosie Galligan.
A city break to Bath a few months ago was where Galligan spotted the ring she wanted, but Packer said it was too expensive and used the upcoming World Cup as an excuse.
Packer then proceeded to sneakily call up and secure the purchase.
“That same week I got it sized up and ordered,” she said.
“I was going to do it on the week we had off after Treviso. I spoke to her dad and the rest of the family about coming over on that day.
“She went and got her nails done and asked if she minded if she got her hair done. It was all set up perfectly.
“I did it where we first started speaking at a reservoir just outside Guildford.
“She was on her way and I texted her to meet me at this location. It was perfect and it couldn’t have been done any better. She was super surprised.”
Upcoming family weddings in 2026 has left 2027 as the likely wedding date, but Packer is aware of the British and Irish Lions’ first women’s tour that September, to New Zealand.
Galligan, 28, is in her prime years and will likely be in the mix for a squad spot.
However, Parker, who is 36 in October, is not convinced she will be in contention by then.
“With the back row at the Red Roses and at every other nation, I think I would only be going to the Lions if I was water girl,” Packer joked. “I would want to be there in some capacity, but playing in 2027 there will be some really incredible world class players.
“Rosie might want to play in it, so it [the wedding] will probably be after the Lions tour.”
