Interesting to see these comments at the press conference (
https://postcourier.com.pg/four-tests-ahead-kumuls/) about the PM XIII fixture:
He also said the change to dates for the Prime Minister’s XIII match that will be held on October 6.
“This date has changed from a week before the grand final to a week after the grand final and will be called the Prime Minister’s XIII Test.
“After the Prime Minister’s XIII last year we saw that most of our top players were still in the finals series,” Rau said.
“The sponsors and the people have spoken about the team’s performance against the Australian Prime Minister’s XIII and the NRL has heard our request. They have gone back and moved the annual fixture a week after the grand final … its good they heard of our views.
Surely they won't reclassify this match as a Test? That said, it would be nice to see the Kangaroos play 3x Tests in 2018...
