It was won by world champion Peter Sagan in a sprint finish.

The opening stage started in Port Adelaide, which hosted the race for the first time since the inaugural Tour Down Under in 1999.

Classification leadership table
In the 2018 Tour Down Under, four different jerseys were awarded. For the general classification, calculated by adding each cyclist's finishing times on each stage, and allowing time bonuses for the first three finishers at intermediate sprints and at the finish of mass-start stages, the leader received an ochre jersey. This classification was considered the most important of the 2018 Tour Down Under, and the winner of the classification was considered the winner of the race.

Additionally, there was a sprints classification, which awarded a green jersey, a change from red in 2017. In the sprints classification, cyclists received points for finishing in the top 10 in a stage. For winning a stage, a rider earned 15 points, with one point fewer per place down to 6 points for 10th place. Points towards the classification could also be accrued at intermediate sprint points during each stage; these intermediate sprints also offered bonus seconds towards the general classification. There was also a mountains classification, the leadership of which was marked by a white jersey with navy polka dots. In the mountains classification, points were won by reaching the top of a climb before other cyclists, with more points available for the higher-categorised climbs.

The fourth jersey represented the young rider classification, marked by a white jersey. This was decided in the same way as the general classification, but only riders born after 1 January 1994 were eligible to be ranked in the classification. There was also a classification for teams, in which the times of the best three cyclists per team on each stage were added together; the leading team at the end of the race was the team with the lowest total time. In addition, there was a combativity award given after each stage to the rider(s) considered, by a jury, to have "instigated the most attacks, breakaways or assisted their teammates to the best advantage".
