The Australian singer, who is a judge on the reality television show alongside Kyle Sandilands and Brian McFadden, said that her TV commitments are part of a "bigger picture" that involves partner Kris Smith and baby son Ethan.
Minogue told Sandilands on his 2DayFM radio show: "I don't really know what I'm going to do next year, but obviously for me to make a decision it's always involving the family and what am I doing and what Kris [is] doing and where we're going to be and Ethan. It's kind of the bigger picture that I look at."
Both Sandilands and Minogue also confirmed that after tonight's grand final, the judges' contracts with Australia's Got Talent will be "up". This, combined with Minogue's exit from The X Factor in the UK, has sparked rumours that she may take a break from showbiz and concentrate on her family.
Earlier this year, Minogue and Smith were rumoured to have split amid reports that she put her career first and treated him like a member of staff. They later released a statement insisting that they were still together and happy.
The Australia's Got Talent grand final takes place from 7.30pm tonight.
