Giovinazzi was confirmed prior to November's United States Grand Prix to be staying at the Alfa Romeo team alongside Kimi Raikkonen for 2020.
"There's many things I can take from this season into next season," Giovinazzi said. "Starting with Melbourne next year, I will be much ready and I think it will be important for me and Kimi to work really hard this winter.
"We will try to work as hard as we can to have a good car and I think this is the most important thing for us and the team.
"I think Monza and Singapore, but also Brazil was the best result for us. I think these three are really good memories. If I think of bad memories, I think Spa.
"But I think you need bad memories to learn from them and I can come back stronger next year.
Giovinazzi reflected on what was a poor season finale for the Alfa Romeo team in Abu Dhabi just under a fortnight ago but was determined to use the post-season tests and winter break to come back stronger in Melbourne next March.
"It was for sure a difficult race," Giovinazzi added. "We tried different strategies, I started on the softs and we have a good few first laps but after that, I was on of the first to go onto the hard tyres and then got stuck behind the Williams with no DRS.
"It was just a difficult race and the pace wasn't really there. Now, I just want to focus on 2020 and with our tests on Wednesday and try to work really hard in the winter to be better for next season."
