The German had been a regular member of the world's top 10 without challenging for the game's biggest prizes but she played some outstanding tennis in Melbourne 12 months ago, upsetting Serena Williams in the final, to truly announce her name to the world.
She didn't fade either, pushing to beat Karolina Pliskova in the New York final before ending the season as the world number one, ending Williams' 186-week reign in the process.
Kerber also reached the final of Wimbledon, where Williams took her revenge, not to mention the Olympics, to show what a consistent performer she now is.
Her left-handed serve is a decent weapon and while she's unlikely to hit too many players off the court, her ability to stay in rallies and grind opponents down is notable.
She may have suffered a slight setback in Brisbane recently when losing in the quarter-finals to Elina Svitolina but will still head to Melbourne very much as one of the favourites.
