This weekend will be Stanaway's first time racing in Supercars.
"I only ever dreamed of doing two things growing up. I wanted to race Formula 1 or Supercars," he said.
"I've never followed closely any other form of motorsport. Now that my single-seater dreams seem to be over after a lot of years, I am so fortunate to be offered the chance to drive in Supercars."
Stanaway, who raced successfully in both GP3 and GP2 championships, has realised his aspirations of racing in Formula 1 are over, and therefore he wanted to return to this side of the world as his base.
Stanaway feels he has a real advantage when it comes to endurance racing.
He usually drives in races from six and 24 hours duration. While a lot of the Supercar drivers look to the upcoming enduro rounds as their longest, it will actually be the shortest races he does this year.
He is looking forward to co-driving with Chris Pither and he's enjoying being part of the Super Black Racing team.
Stanaway knows he has a few things to get his head around before the Sandown 500 this weekend. The cars are heavier than he is used to and he said that while the distance and time won't be an issue for him, it's the category and circuits that he must figure out.
"The difference between good and great drivers in V8 Supercars is measured by extremely small margins and it is those margins that I need to learn.
"There's a lot of weight of performance on co-drivers at Sandown, with our own qualifying and our own race that goes towards the overall start positions. It is an important role."
While Sandown is the main focus this weekend, Stanaway can't help but think about the Supercheap Autos Bathurst 1000 in three weeks.
"I grew up as a kid watching Bathurst on television and that's how I fell in love with motorsport. I can't quite believe that I will be racing there. Somehow it does not feel real."
There are three practice sessions today, qualifying and two qualifying races on Saturday which will sort grid positions for Sunday's 500km race.
