The 35-year-old has altered his game style dramatically since debuting as a 17-year-old, in an attempt to get the best out of himself and his younger teammates.
"As a batsman, I've changed a lot," Allenby said.
"I started off as an opener and was really defensive, but in the last few years I think I've become more aggressive and more flexible.
"I've also shifted around the order a bit, trying to develop some of the youngsters and get them used to playing up the order."
Allenby, who has played his entire first grade career at the club, was initially unaware he had passed any sort of milestone until he received an email on the following Monday morning.
"I literally had no idea," he said.
"It's not something I set out to do, I've never really set targets or goals like that, but I felt really proud once I found out.
"For me it has always been about playing my role for the team week to week, staying fit, keen and motivated."
Although satisfied with where his career is currently at, Allenby always harboured ambitions to represent his state.
"I just wanted to play for WA," he said.
"Everything I did was geared around getting there, playing, training, everything.
"When it didn't really eventuate, I had to get my head around it and just continue doing what I was doing."
The Tigers, currently undefeated and sitting on top of the Alcohol.Think Again Premier Cricket ladder, are looking to add another trophy to their club rooms as Allenby believes his side has what it takes to keep the momentum rolling.
"I think with the players we have available, we should be towards the top of the league at the end of the season," he said.
"We have won two One-Day competitions in a row, but we have missed out on the Two-Day flag for a while now, so I would expect we would be challenging for that.
"I think we're a really well-balanced team with good batting depth, so there's no reason why we can't get there."
Claremont Nedlands will begin day two of its two-day match against Mount Lawley needing to chase down 247, on Saturday November 18 at 11:40am at Creswell Park.
