After a phenomenal 2017 season which included two Grand Slams and five other trophies, Federer will start the new campaign at mixed teams’ event again.
The 36-year-old landed in Perth on Thursday morning in Australia with his family and is expected to practice later in the day.
Twelve months ago, Federer arrived in the Australian city with low expectations after missing the previous six-months through injury.
But Federer enjoyed himself greatly with fellow Swiss Belinda Bencic, playing in front of record crowds over the week.
Federer, who will be partnered again by Bencic, will use the event as a warm-up for the Australian Open which starts on January 15.
And the 19-time Grand Slam champion is in a positive frame of mind.
“It’s totally different this time around,” said Federer.
“I had a great off season. I mean, I did have a good off season too last year but I just wasn’t sure what to expect.
“Now expectations are higher but at the same time I try to remind myself just don‘t think it’s normal and realistic to aim for the same things I did this year in 2017.
“I’ve got to try and keep it cool. Try my best and see what happens but the preparation’s been good so far. We’ll see how things go.
“It worked out perfectly this year, (winning) at the Australian Open. Of course, that’s a good omen. I hope that winning or losing the Hopman Cup is going to be good for me.
“Obviously looking ahead to Melbourne, I really hope that Hopman Cup’s going to give me everything I need here.
“I had a wonderful time (in 2017). I can’t wait to see all the fans again because they came out in big numbers and supported me.”
