Warbrick is set to play his 50th NRL match against the Eels at AAMI Park on Sunday, the former Olympic silver medallist making the transition from rugby sevens to rugby league four years ago.
Turning 27 this week, the Kiwi speedster said he'd already achieved beyond his expectations when he crossed codes.
Part of Melbourne's losing grand final line-up last year, Warbrick won the club's best back award for the second consecutive year, was named to debut in the New Zealand team in the 2024 Pacific Championships and turned out for the Maori All Stars side last month.
"I feel it's (50) has come around pretty quick, it's been a great journey so far for me, more than what I've ever imagined," Warbrick told AAP.
"Sometimes I don't really reflect on everything that's happened but I feel like this off-season I've probably had a bit of time to do that and I'm really grateful for the experiences and journey I've had so far.
"It's definitely motivated me more to keep pursuing higher rep honours, it's definitely made me pursue bigger goals, made me more ambitious."
Warbrick didn't play in either of the Storm's losing pre-season matches after squaring off for the first time against the Indigenous All Stars in mid-February, which he said was an "intense" encounter.
"I probably played more minutes than I expected and the game itself was really intense, I didn't know what to expect - being that it was my first All-Stars game.
"It was a very intense game, very fast-paced, a lot of footy so it was probably a decent first hit out.
"The coaches were happy for me to rest up and recover and just look after the body heading into round one."
Posing another aerial attacking threat on the other wing, Coates has also been sidelined since injuring his ankle at training but Warbrick said his teammate was ready to play.
Craig Bellamy is looking to keep his incredible round-one winning streak alive, which started when he took over as coach in 2003.
"Xavier's looking great, he's been training really well and he's obviously done everything that he needs to do in terms of his rehab and looking after his body and he looks fit and ready to go," Warbrick said.
"If he wanted to, he probably could have pushed for that second trial, but I feel like that extra time week allows his body to recover even more so he's looking good."
