With two second place overall finishes at the Dauphine in his career, Porte is determined to break through and will go into Sunday's stage eight in pole position after claiming yellow at La Plagne.
However, it is not the first time the 36-year-old has gone into the final day at the Dauphine in the lead after he lost the title to Jakob Fuglsang at the end of a frantic stage in 2017.
He hopes the lessons he learnt from that loss can help him achieve victory in a race that has so far eluded him.
"I've been here before, four years ago, and I know how the last stage of this race can pan out, so I know it's going to be a battle tomorrow. But I'm happy. I'm 36 years old and I'm wearing a jersey," he said.
"This is one of the races that I haven't won that I'd really love to win. I know everybody's going to want to attack, but we have a strong team here. We've got Geraint (Thomas) up there too and I don't think we're going to be fussy as long as one of us wins."
Porte's Ineos team has been top performers at this year's Dauphine and really excelled as the race took to the mountains.
The Aussie revealed he feels at home at the British based team after rejoining them in the offseason and is enjoying being able to focus on racing.
"It's fantastic to be back racing in this team, I enjoyed my last years but I do feel like I'm home here," he said.
"I loved my time at Trek, but I did feel the pressure, and also at BMC. I like being here where I never really get asked to do interviews and don't have to do much social media. I get left alone. And I think that's how I like to be and I think in two years' time, I'll be retired and you won't hear a thing from me and it's just how I would like it to be."
