However, the 28-year-old is looking forward to fatherhood and will put that before tennis.
"I'm going to fly home I think," Murray said.
"We spoke about it and chatted and obviously it'd be disappointing if I was to get in that position and not be able to play the final.
"But I'd be way more disappointed winning the Australian Open and not being at the birth of the child.
"Hopefully it doesn't come to that. It's going to be a big change but I am very excited about it. I have got a few weeks of tennis here and then I'll take February off to spend time with Kim."
Murray hasn't been happy with his practice since arriving in Perth but his near flawless win over de Schepper left no room for concern.
"I hadn't actually been playing well in practice at all. I've been struggling and I don't know exactly why that it is, but I get on the match court and it's different," he said.
"It's better to have it that way rather than play great in practice and struggle in matches. I practice hard and I got used to the warm weather which can be brutal. I feel good."
