Participating in Force India in 2014, Perez has had four podiums since then, the last of which was in the 2016 European GP.
The Indian team, although they spent the best season in 2017, neither Perez nor the wrestling newcomer Esteban Ocon could get in the top three in 20 races.
Perez says he is aware that he will fight teams like Renault and McLaren while aiming to end this year's 33-race podium series.
Force India made the best eighth in the pre-season tests with 10 teams.
"You always go to Melbourne with hope, there are a lot of questions looking for answers, and you'll start to see how your competitive power really is."
"At the same time, this is not a typical race, because almost nothing can be predicted, and usually a race is the key to getting a good result."
"I am in good shape for the season and I feel myself ready, I want it to be my best year in Formula 1 and I want to go back to the podium."
"During the tests we saw that the teams in the middle group were very close to each other in terms of performance and I think there is less difference in front of the grid.
Ocon Force trusts India
Ocón, who will go into the second season with Force India, hopes to make a strong start to the season.
The Indian normally brought its first major update to the Spanish Grand Prix in May, but this year it chose a different program.
Ocon said, "I think we are going to be in the middleman in Melbourne, and we did a real test in the second week in Barcelona and I felt comfortable in the car, and we will have some new pieces for Melbourne.
"Albert Park is a very old track, very narrow and very technical at the same time."
"To get a good lap, you have to drive clean and be careful, after all, there are low and medium speed turns."
"I think the most exciting part of the track is the high-speed turn between the 11th and 12th bends.
