He's only 19.

But the Woodford export, who moved to Geelong three years ago, knows he must dig in if he wants to realise his dream of playing first-class cricket for Victoria.

He said the chance to play in the futures series for his state last season "probably showed me how much harder I have to work to go to the next level".

"It was good to play that (four-day) game. I faced Trent Copeland and some pretty good bowlers and it gave me an insight that I need to worker harder than I have been," Jackson said.

"To make it, you can't just go through the motions, you've always got to be working on something."

He's already identified one area of his game he can improve on when the 2020-21 season starts.

"I'll face a bit more short-pitch bowling (at training)," Jackson said.

"I am pretty small so all the older and bigger guys down here try and pepper you with bouncers.

"I love it. It's a pretty good challenge."

Jackson made 107 on debut for Geelong's First XI in 2018-19.

He followed with a 136 and then chipped in with 122 in its grand final loss.

The top-order bat entrenched himself in the club's top team last season, scoring 607 runs at an average of 31. He reached the ton (119 and 113) twice.

Jackson, who honed his craft in the Warrnambool and District Cricket Association, prides himself on making himself at home at the crease and has incorporated running sessions into his off-season to lessen fatigue while batting.

"I hate running. I am not really good at it but it is something I am going to have to get better at and it will benefit me," he said.

"If it wasn't for cricket I definitely wouldn't be out running.

"I have a little running program with Cricket Victoria so I follow a couple of their runs and then make up a couple of my own.

"A lot of it is interval stuff, like stop-start, because it is similar to cricket.

"At the moment I've been trying to do one or two intervals and one day a week I try and run as far as I can."
