A well-defined and slow-moving tropical low, 23U, formed near Christmas Island on 3 April, on the same day where a trough spawned another system in the Northern Region near Timor. It caused some sporadic rain showers on the island. On 8 April, the system began interacting with Cyclone Seroja to the northeast, due to the Fujiwhara effect, causing both systems to weaken, though the tropical low subsequently strengthened into Tropical Cyclone Odette later that day. On 9 April, Odette began to weaken, as the storm was gradually absorbed into Seroja, which was strengthening around the same time. On 10 April, Odette had lost most of its convection, and the storm began to be drawn into Seroja's circulation. During this time, Odette weakened further into a tropical low. Later that day, Odette was fully absorbed into Seroja, and the BoM issued their final advisory on the storm.
