The Kiwi heavyweight prospect has largely been confined to his hotel this week as he awaits his bout with Brazilian Marcelo Luiz Nascimento in Oberhausen tomorrow.
But while this fight is important as he looks to build on his perfect 7-0 record, the 22-year-old was also able to take on some historical knowledge this week.
Parker has never been to a memorial service on Anzac Day but he was given the chance to walk around the Rheinberg War Cemetery on Thursday.
There's 3326 Commonwealth servicemen buried or commemorated at the site, including 104 New Zealanders and 240 Australians.
They were all airmen with the Royal Air Force and were laid to rest there because they were shot down in action over western German air space during World War 2.
Parker will fight on the undercard of Australian Alex Leapai's world title tilt against heavyweight champion Wladimir Klitschko at the Konig Pilsener Arena tomorrow morning (NZT).
Parker and Leapai both took time to walk around the Rheinberg site as the magnitude of the occasion hit them.
Reading gravestones of servicemen, some of who died in their teens, can be jarring.
The white headstones were lined across the pristine site, which is neatly maintained.
Parker and Leapai both signed the guest book, which invited people to give their signature, say where they were from and offer a comment.
Leapai signed as being from his country of residence Australia, his birth nation Samoa and New Zealand, where he lived as a youngster.
He finished with: 'Lest we forget.'
Parker nominated New Zealand and Samoa as a nod to his country of birth and his heritage, while he signed off with: 'Respect.'
"It's a great opportunity be here before the fight and seeing this has given us inspiration and extra motivation going in to the fight," Parker said.
"It's a humbling experience being here."
The pair of heavyweights will channel the Anzac spirit in their respective bouts.
"Having my brother Alex walking around with me, it's a great feeling, and we are both going to take a lot from what we've seen," Parker said.
Leapai (30-4-3) is a heavy underdog against the Ukrainian Klitschko (61-3) but said his trip to Rheinberg was a highlight of the week.
"It's given me a great boost," the 34-year-old said. "I can't compare to what they've done but come Saturday, I'm going to put everything on the line and hopefully bring the right result and take it home."
Parker should have an easier outing against Nascimento, although the 1.96m 33-year-old has been handpicked to test Parker.
The Brazilian (17-5) took the fight on short notice as a replacement for Sherman Williams who decided to pull out after he had a falling out with the Klitschko camp where he was employed as a sparring partner for the world champion.
Williams was a stocky opponent at 1.80m so the Parker camp has adjusted their strategy on the run to take on a taller man.
The WBA's Pan Asian Boxing Association interim heavyweight title will also be on the line, which could give Parker the chance to establish further ranking points and get his name out there.
Parker's parents and brother John joined him in Germany this week, which put the Kiwi at ease.
"I'm feeling really good, really relaxed and I've got a lot of familiar faces here, which makes it easy and a happier environment for me."
