As we learnt at the ASB Classic in Auckland, the first part of the tennis season can always be hard to predict due to players enduring tough off-seasons or recovering from injury.
Subsequently, with players not particularly performing according to their rank before the first grand slam of the year, it makes predicting it very hard to do.
Instead, here are the players you should be keeping your eye on to make an upset in the upcoming fortnight.
Nick Kyrgios - like him or loathe him, he's got some talent. Ever since he knocked over Rafa Nadal at Wimbledon in 2014, he's showed that he's got the ability to go deep into a grand slam.
His game is flexible enough to not be perturbed by court speed, which is handy as the surface speed in Melbourne can vary depending on weather.
He may be hard to watch at times but he's got another big upset in him and could be good for a quarter or a semi-final appearance.
Karen Khachanov - currently ranked 53 and while you've not likely heard a lot about him, the Russian is definitely part of the men's next generation.
A fourth round appearance at this year's tournament is probably a bit of a stretch considering he's set to meet ASB Classic winner Jack Sock in the second round should he get past the tricky Frenchman Adrian Mannarino in his opening match.
However, he showed in the back-end of 2016 that he could more than match it with the best, winning his first ATP title in China by beating Joao Sousa, Mannarino, Feliciano Lopez, Victor Troiki and Albert Ramos-Vinolas in the final.
He might only make the third or fourth round but he'll upset one or two seeds in doing so.
Joao Sousa - the ASB Classic finalist, arrives in Melbourne in some very good form after a patchy end to last season and the compact right-hander will fancy his chances at progressing late into the first week at least.
In the same half of the draw as world number two Novak Djokovic, Sousa gets a qualifier in Australian Jordan Thompson first up, before a likely match-up against number eight seed Dominic Thiem. While Thiem is a tough proposition, he's coming off a poor loss to Brit Daniel Evans in Sydney and Sousa does have the game to trouble him.
He may not have it in him to reach the second week but he is capable of an upset in the first.
Alize Cornet - a finalist at last week's Brisbane International, Cornet is one of those players that when she's on, she's really on.
The Frenchwoman beat some quality opponents in Brisbane and she'll need to do the same this week with a potential third round clash with either Agnieszka Radwanska or Dominika Cibulkova looming.
Cornet has a heavy forehand and is very entertaining to watch.
Simona Halep - the Romanian has been around for some time with her career underlined by a short appearance at world number one. But since, the world number four hasn't been able to consistently beat top 10 ranked players when it matters.
Arriving in Melbourne early this year to prepare, if the weather is cool and the court pace is slower, it will play in her favour with her game most suited to clay. She has been dealt a very good draw where the first seeded player she'll meet will either be Monica Puig or Kiki Bertens in a potential fourth round clash.
Naomi Osaka - billed as the next big thing in women's tennis but struggled with injury in the first fortnight of the season. Had a very good back-end of 2016 and her hard hitting will suit the pace of Melbourne's courts.
There are still a few questions over her movement and she's likely to run into seed Johanna Konta in the second round, but if she can concentrate on timing the ball well, she's going to give Konta a very good run.
