Miller and Trinity travel to Leigh on the weekend to face Warrington in the Cup.
The Australian halfback is fully aware of the importance of the match, with a spot in the final up for grabs, to both the Wakefield club and its fans.
“Definitely its a massive occasion for the club, the fans and ourselves,” he told Love Rugby League.
“We know how long its been since the club have been in a big game like this besides the Million Pound game so we’re looking forward to a big game this weekend.”
Miller has decent Cup experience, having played in the final at Wembley with Hull FC in 2013.
“Definitely the Million Pound game was something else, I was lucky to play there [a Cup final] a few years back at Hull so that was probably the biggest game of my career,” he said.
“But it’s definitely one of them and it’s going to be a massive occasion.
“We know how hard this week’s going to be, Warrington are one of the biggest benchmarks and have been for a while now.
“We’re confident in the group we have and what we’re doing as a group that we can go out there and give it a good crack.”
“We picked up a few injuries over the weekend and we’ve got a few coming back so not ideal but its the way it is,” Miller admitted.
“We’ve been pretty lucky this year with injuries so it’s a shame it’s happened this week but everyone goes through it.
“We’ve got a pretty deep squad and we’re pretty confident whoever come in will do a good job.”
