Hinkley says he'll keep faith with the Port players who upset Collingwood last weekend.
"We will go in unchanged and look forward to the opportunity to give those boys a chance to play again," he told reporters at Adelaide Airport on Thursday.
Rain is forecast in Melbourne for the sudden-death semi-final, but Hinkley said any downpour was unlikely to force a change.
"The weather forecast is predicting quite a bit of rain ... but I don't think anything will change our minds.
"It (rain) is just something that we have to be mindful of."
The only alteration to Port's squad, to be officially released later on Thursday, is in the emergencies with utility Paul Stewart to replace Cameron Hitchcock.
Stewart hasn't played an AFL game since breaking his left arm in round 19 but has returned to action in SANFL ranks.
"He is one of our more senior players but his broken wrist has held him out," Hinkley said of the 77-gamer.
"But his form last week was really good.
"He could easily come in and play if we did lose someone overnight with an illness or something like that; he would be a logical replacement."
The Cats' talented side means Hinkley is battling to decide which star will be kept on the shortest leash.
Former skipper Dom Cassisi is expected to be the Power's main negating weapon after keeping Collingwood super star Scott Pendlebury to 24 disposals last weekend – his third fewest tally for the year.
But Kane Cornes has also proven invaluable as a negating midfielder this year, as has Andrew Moore.
"There's a smorgasbord – we put [Cassisi] on (Steven) Motlop at some stage last time, we could put him on (Joel) Selwood who kicked four goals, (Steve) Johnson's got us both times we've played them this year," Hinkley said.
"(Andrew) Mackie's a great player down back, there's an enormous amount of players in their side that we could apply Dom to, or Kane to, or Andrew Moore to.
"It's just a matter of making sure what we think's the right matchup – clearly I'm not going to say exactly what that is."
Port will name an unchanged line up to the one that defeated the Magpies last weekend, but Paul Stewart has replaced Cameron Hitchcock as one of the emergencies.
While rain is predicted for Friday evening, Hinkley said he didn't think there would be a late change.
When these teams met in round nine Geelong sprinted out to a 39-point lead at quarter-time and in round 20 it was a similar story with the Cats leading by 31 points at the first break.
Hinkley said Port must fire early but insisted it mustn't fear Geelong's fast starts.
"It's really important for us that we perform really well at the start of the game and we make it a contest," he said.
"But we can't go away from what we do and what we do is play some really defensive football and then attack hard off it."
