[2] TCWC Darwin predicted that there might be an early start to the season within the Timor Sea and slightly above average numbers of tropical cyclones around northern Australia.

[3] Within their outlook TCWC Brisbane predicted that there would be a high amount of activity within the Australian Monsoon, and that the chances of a repeat of the widespread flooding rains were not great due to their being no well-established La Nina.

[4] During September 2008, the New Zealand National Institute of Water and Atmospheric Research (NIWA) and its partners issued a tropical cyclone outlook, for the South Pacific region between 135°E and 120°W.

[5] On 26 September 2008 the New Zealand National Institute of Water & Atmospheric Research issued a seasonal forecast for the whole of the southern Pacific Ocean to the east of 150°E.

[9] The intensification was the result of deep convection wrapping around the center of circulation and Dvorak Technique intensity estimates reaching T3.5.

It then moved off the coast just north of Kuri Bay and redeveloped into a tropical cyclone on 22 December as the storm turned to the north-north east.

[12] Two remote indigenous communities, Kalumburu and Oombulgurri were cut off by flood waters with roads and the airstrips closed.

[13] On 20 December, an area of low pressure, associated with developing convection, formed about 1000 km (560 mi) east of Darwin in the Gulf of Carpentaria.

[17] About 36 hours after landfall, the Australian Bureau of Meteorology issued their final advisory on the system as it dissipated over land.

[18] On 23 December, TCWC Brisbane noted that a weak tropical low had formed within the Solomon Sea, about 1330 kilometres to the north east of Cairns.

Heavy rains, estimated at over 150 mm (5.9 in), from Tropical Cyclone Charlotte flooded at least 100 homes in low-lying areas on Cape York including Babinda, Mount Sophia and at Normanton.

On 22 January, TCWC Perth noted that Tropical Low 08U had formed overland, to the north of Broome in North-West Australia.

[24] On 25 January at 11:15am (AWDT), TCWC Perth issued a Tropical Cyclone Warning for coastal areas from Wickham to Exmouth.

[29] Following the storm, the shires of Ashburton, Carnarvon, Upper Gascoyne, Murchison, Yalgoo, Moora, Northam, York, Quairading and Beverley were eligible for disaster assistance from the Australian Government.

[34] Ellie made landfall near Mission Beach at about Midnight AEST, 2 February (1400 UTC), as a Category 1 system and weakened into a Tropical Low.

In Ingham, between Cairns and Townsville, some 50 homes were flooded, with 32 people evacuated to emergency accommodation at a local high school.

[36] On 2 February, TCWC Perth noted that a Tropical Low had developed in the monsoon trough, which was located over the Kimberly region.

Freddy tracked slowly south westward and steadily weakened as it was affected by more wind shear and cooler waters.

On 26 February, JTWC upgraded the system's chances to "good" and issued a Tropical Cyclone Formation Alert.

The tropical low dropped upwards of 112 mm (4.4 in) of rain along the Pilbara coast, causing minor flooding.

Bureau of Meteorology in Perth noted that in post-analysis determined that Gabrielle did not meet the minimum requirements of a tropical cyclone by the Australian definition.

Gales were observed in one quadrant or another throughout most of Gabrielle's life but at no one time did they extend more than halfway around the low level circulation center.

[41] On 4 March, a weak Tropical Low developed in an active trough located over the north western Coral Sea slowly moving south east.

Rescue attempts to retrieve the three crew members were hampered by Hamish and were called off but expected to resume of 10 March.

[47] Early on 23 March the BoM started to monitor Tropical Low 20U that had developed within the monsoon trough, about 900 km (560 mi) to the northeast of Mackay in Queensland, Australia.

[48][49][50] The system subsequently moved southeastwards away from the Queensland coast, before it was named Jasper by the BoM later that day, after it had developed into a category 1 tropical cyclone.

[52] As the system moved out of the basin the BoM reported that Jasper had peaked as a category 2 tropical cyclone with 10-minute sustained wind speeds of 95 km/h (60 mph).

During 28 April the JTWC issued their final warning on Kirrily before the BoM downgraded the storm to a tropical low.

[59] In addition to the systems included above, the remnants of Tropical Cyclones Bernard and Innis moved into the basin on 21 November and 18 February.

After the season, the name Hamish was retired by the World Meteorological Organization's RA V Tropical Cyclone Committee.
