"It was hard at first as I would get last-minute calls to race in different championships. I'd turn up at the track to just fill in for a driver so I didn't have much time to get used to the car or track and not many tyres.
"It was fantastic to be able to sign up for a full season, do pre-season testing. It's paying dividends now.
"I'm also racing in the China GT, the Asia Le Mans series in both sprint and endurance, the Blancpain series, and I also coach in the Thailand Porsche series. So it's getting pretty busy, which is really cool.
"Pretty much for the next four months I'll be racing every weekend in a different country."
Asia has a healthy number of new and growing race championships and categories and a lot of opportunities for drivers looking to get a foot in the door to build an international profile. And while Bamber is keen to race as much as possible, his primary goal is focusing on the PCCA.
One-make championships are one of the hardest to stand out in, as the skill level is pretty much the same and the drivers are all in the same car, so it's more about talent rather than machinery.
"Earl has shown what winning this championship can do for you and how much Porsche will support you. This year the field is high quality and valued all round the world.
"Most of the time if you do well in Carrera Cup people notice, and while the phone doesn't ring off the hook, you've put yourself in the frame and people notice," he said.
Bamber's hope is to follow his brother and get selected for a Porsche scholarship that in turn will open more doors. It's open to drivers under 26 years of age (Bamber is 23) and selection is not just based on race results.
"You don't actually have to win it [PCCA] to be selected for a scholarship. Basically Porsche China have a driver pool where we go away on boot camps.
"It's about fitness, media training and you get rated on every single thing about our driving and a whole heap of other stuff. There are six of us in the pool and we find out next week who's going to get picked to go to Europe in three weeks' time," said Bamber.
It's been a struggle for Bamber to get where he is and he's single-minded in grabbing every single opportunity that comes his way. The scholarship is top of mind for him as a way to continue climbing up the professional racing mountain.
