Rea was second fastest at Phillip Island, second only to Alex Lowes, and he believes that speed will carry through to the season ahead.
Website thecheckeredflag quoted the Northern Irishman explaining how confident he is feeling ahead of the race weekend.
Rea said: "I am happy to go into race weekend like this, although we still have some things to work on. It is just a bit of an unknown really so I am just working with my guys on the bike and trying to focus on going as fast as we can for all 20-laps. I was able to do a long run today and was able to keep most of the laps in the 1'31s. I do not know how competitive that is going to be but for now it is a start and we have that information to work with.
"We have done all the testing we can do, so I am happy that race weekend is coming. All the anticipation and excitement is there but we do not have to wait long now. I am looking forward to the lights going out on race day. Definitely, this is the best position we have ever been in at the start of a season."
Rea's team-mate Tom Sykes is equally pleased, saying: "In general I am relatively happy and we set some good lap times at the end on used tyres. Credit to the boys and Kawasaki for giving me what I need. The Ninja ZX-10R is working well and if it does what I want it to then we can have a good race weekend.
