Hinkley is contracted until the end of next season but faces exiting the finals with consecutive defeats for a second-straight season should Port lose on Friday night.
"I'm not going to be a smart ass here in any way, shape or form - but I'm contracted," Hinkley told reporters on Thursday.
"That is what the board have told me all the way through.
"They have shown me great support the entire journey. I trust that that will always be the same."
Hinkley said of speculation he would face the axe or step down should the Power lose: "That's uneducated. It's not the facts.
"I get why the conversation keeps coming up," he said.
"But the reality is, I'm preparing this week to help our team find a way of getting in to a prelim final.
"That has got too much riding on it for me to spend any time in those other places you want me to go. I just won't go there."

Hinkley, in his 12th season at Port, will coach the South Australian club for a 273rd time on Friday night, equalling Mark Williams's record as the Power's longest-serving coach.
"Those sort of things, in some ways remarkable that I got to this point," he said.
"But the reality is I reflect on those things after your career. And hopefully there's a lot more to go."
The 57-year-old holds the unwanted record of coaching the most games in VFL/AFL history without reaching a grand final.
