A longer, more severe season was predicted, with an above normal potential for bushfires—particularly along the west and east coasts—as the result of the strengthening El Niño over the Pacific Ocean and warmer sea temperatures in the Indian Ocean.
In Victoria, large areas of the Wimmera and the Western District had their lowest recorded rainfall in the three years to 31 July 2015, and significant areas of the Goldfields, North Central, Otways and Yarra Valley recorded "very much below average" rainfall over the same period. In Western Australia, the Goldfields-Esperance, Peel and South West regions were expected to experience "above normal fire potential" due to a lack of rainfall, soil dryness and high fuel loads; the Peel and South West regions were at specific risk, having experienced their 8th driest year on record in 2015. The Great Southern, Peel, Perth and South West regions suffered record rainfall deficiencies for the 16-year period to 31 March 2016.
The areas that suffered the greatest rainfall deficiencies during the season typically receive the majority of rainfall from cold fronts and low pressure systems, autumn through spring. However, continental Australia has experienced a decrease in this activity over recent decades, as high pressure systems have become more dominant. These longer-term deficiencies has a great effect on the drying of woodland fuels, particularly in the Jarrah forest of Western Australia's South-West and the forests of Victoria's Otway Ranges, which witnessed significant fires during the 2015/16 season.June
On 1 June, a 1 hectare (2.5 acres) bushfire completely destroyed one house and damaged a second house at Copacabana in the City of Gosford municipality of the Central Coast region. One civilian was treated for burns received while fighting the fire.July
On 31 July, a fire ignited in the bushland of the Jamison Valley, nearby Wentworth Falls and within the City of Blue Mountains municipality. Over the next 12 days, one house was damaged and 30 hectares (74 acres) of forest were consumed by the fire, which spread rapidly due to strong winds of up to 80 kilometres per hour (50 mph). At least 150 firefighters and several water bombing aircraft were required to bring the fire under control, and it was declared extinguished on 12 August.November
On 26 November, a Rural Fire Service volunteer firefighter collapsed and died while fighting a fire 5 hectares (12 acres) in size near Stanford Merthyr in the City of Cessnock municipality.

On 25 November, during the major run of the Pinery fire, two fatalities occurred: Janet Hughes, 56, perished while fleeing in a vehicle outside Hamley Bridge; Allan Tiller, 69, died while fighting the fire on a neighbour’s property in Pinery itself. The Pinery fire destroyed or rendered uninhabitable 87–91 houses, and completely destroyed 388 non-residential structures, 93 pieces of farm machinery and 98 other vehicles. It also caused significant damage to rural produce; 53,000 poultry and 17,500 head of livestock perished.December
On 31 December, a fire destroyed four non-residential buildings, four vehicles and 310 hectares (770 acres) of farmland around the Mosquito Hill area of the Alexandrina municipality. 120 firefighters and 4 aircraft assisted in containing the fire the same day as its ignition and 4 people were injured during the blaze.March

On 5 October, one house and 10 hectares (25 acres) of scrubland were destroyed by a bushfire at Wensleydale in the Surf Coast Shire, south-west of Geelong. The fire was contained the same day by Country Fire Authority firefighters.
On 6 October and during the week following, 6 houses, 15 non-residential structures, 5 vehicles and 3,100 hectares (7,700 acres) of forest and paddock were destroyed by a significant bushfire in the Lancefield area of the Shire of Macedon Ranges, 70 kilometres (43 mi) north of Melbourne. Communities affected by the fire included Baynton, Benloch, Nulla Vale, Lancefield, Pastoria and Sidonia. At least 22 aircraft were utilized by the Country Fire Authority to fight the fire before it was contained on 12 October. The fire had been lit a week earlier as part of a controlled burn in Cobaw State Forest overseen by the Department of Environment, Land, Water and Planning, however the authorities had lost control of the blaze in strong winds and hot conditions. An independent report into the blaze, released in November 2015, criticized the initial controlled burn as inadequately planned and inadequately staffed. The then Victorian Environment minister Lisa Neville admitted failures in the risk assessment taken prior to the approval of the controlled burn, and the following quote of hers was reported by The Age on 19 November 2015.November
On 17 November, one "weekender" holiday house and 50 hectares (120 acres) of forest were destroyed by a bushfire at Devon North in the Shire of Wellington, 6 kilometres (3.7 mi) north-west of Yarram. The blaze originated from a controlled burn to reduce the fuel load on private land.December
Over 19–20 December, temperatures reached up to 45 °C (113 °F) across Victoria—including 41 °C (106 °F) in Melbourne, Victoria—and extreme fire conditions were felt across the entirety of the state. During the following week, Victoria suffered three significant fires; 4,600 hectares (11,000 acres) of forest and farm land were burnt by the Scotsburn fire, 7,000 hectares (17,000 acres) were burnt by the Barnawartha fire, and fire started by lightning in the Otway National Park near Lorne would continue to burn past Christmas and be dubbed the "Lorne-Jamieson Track" fire.
On 19 December, 14 houses and at least 30 non-residential structures were destroyed by the Scotsburn fire, which also ravaged significant areas of rural property in the City of Ballarat and Shire of Moorabool municipalities. Suburbs and towns affected included Clarendon, Durham Lead, Elaine, Garibaldi and Scotsburn. The fire had been ignited on the same day by a landowner using a slashing machine; 500 firefighting personnel and 8 aircraft attended the fire, and it was contained by 20 December.
On 20 December, the Barnawartha fire destroyed 4 houses and several non-residential structures in the Shire of Indigo, as well as causing the deaths of 1,200 head of livestock. Near Wodonga, several dozen families were evacuated when the uncontrolled grass fire advanced rapidly on the town, however damage to the town itself was minimal. There were also fears that the fire may advance on Yackandandah, however rainfall of up to 20 millimetres (0.79 in) on the night of 20 December slowed the spread of the fire and limited damage to Barnawartha and Indigo Valley.
On 25 December (Christmas Day) severe fire conditions, including a strong northerly wind, led to the Lorne-Jamieson Track fire in the Otway National Park jumping containment lines and impacting numerous communities situated along the Great Ocean Road in the Shire of Colac Otway. A total of 116 houses were destroyed—98 in Wye River and 18 in Separation Creek—on 25 December, and over 2,500 hectares (6,200 acres) of dense forest were burnt by the time the fire was contained on 21 January 2016. Although structural damage was limited to the two communities of Wye River and Separation Creek, the township of Lorne was advised by the Country Fire Authority to evacuate from mid afternoon on 25 December, the communities of Kennett River, Grey River and Wongarra were evacuated several times, and the Great Ocean Road was closed for several days after the 25 December run damaged parts of the road infrastructure.
Lightning ignited the Lorne-Jamieson Track fire in inaccessible country on 19 December, and during the week prior to the 25 December run the fire had burned to a distance of approximately 4 kilometres (2.5 mi) north-west of Separation Creek. On the day of the run, a Keetch–Byram Drought Index of 80 was recorded at Aireys Inlet and 83 at Cape Otway; these are considered ‘serious’ with respect to fuel ignition potential. In Wye River, a north/north-westerly wind with gusts of up to 33 kilometres per hour (21 mph) and humidity hit a low of 17% at 16:30 AEDT (UTC+11) were observed. At 11:30 AEDT (UTC+11) the emergency siren was sounded in Separation Creek and approximately three hours later the fire front impacted the communities.January
On 18 January, one house, 6 non-residential buildings and 90 hectares (220 acres) of scrub and forest were destroyed, and another house damaged, by a bushfire that burned through the Crib Point and Stony Point communities in the Shire of Mornington Peninsula.

On 1 October, a bushfire destroyed 2 sheds and 6,500 hectares (16,000 acres) of bushland in the Town of Port Hedland municipality. Residents of Bosna Estate were evacuated before at least 20 firefighting appliances helped contain the blaze. The bushfire was first reported on 29 September.November
During November, the Shire of Esperance suffered two significant fires and a fire complex; 128,000 hectares (320,000 acres) were burnt by the Cascades fire, 18,000 hectares (44,000 acres) were burnt by the Merivale fire, and 164,000 hectares (410,000 acres) were burnt by the Cape Arid complex of fires. On 17 November, during the major run of the Cascades fire, four civilian fatalities occurred in vehicles traveling on Griggs Road in Scaddan. The Cascades fire destroyed one house, 16 non-residential structures and dozens of vehicles. There was also significant damage to rural produce; approximately 4,500 head of livestock perished and 30,000 hectares (74,000 acres) of crop—constituting about 500,000 tonnes of grain—were burnt. In addition, the Merivale fire destroyed two houses in the Stockyard Creek area, and the Cape Arid complex destroyed large areas of Western Ground Parrot habitat.January
During January, the shires of Harvey & Waroona suffered a number of significant fires; 70,000 hectares (170,000 acres) of forest and farmland were burnt by the largest of these fires, which ignited on the night of the 6 January and was dubbed the "Waroona" fire.
On 7 January, two civilians perished when the fire-front of the Waroona fire burned into the center of the Yarloop townsite; Malcolm Taylor, 73, and Les Taylor, 77, both died within their own houses. During the time that the fire-front passed through Yarloop, it destroyed 121 houses, 18 buildings of commercial or community significance—including a fire station, a hospital, a hotel and a hall—and the historic Yarloop Workshops. In the 17 days between ignition and being extinguished, the Waroona fire destroyed at least 162 houses and a significant amount of other property in the communities of Cookernup, Hamel, Harvey, Lake Clifton, Preston Beach, Waroona, Wagerup and Yarloop. Public road access to Yarloop was not restored until seven months after the fire when roadblocks were finally removed 11 August 2016.
Effects of the Waroona fire were widespread in southern Western Australia; falling ash in the Eaton, Australind and outer Bunbury areas caused service stations to stop pumping fuel, and the closure of both the Forrest Highway and South West Highway prompted the cancellation of the 2016 Southbound music festival when it cut off access to Busselton. However, the event was partly revived as a benefit concert to raise funds for fire victims.
The size of the fire allowed the creation of its own weather pattern with rising heat and particulate matter facilitating the development of both pyrocumulus and pyrocumulonimbus clouds. The rare weather event created unpredictable winds with sudden gusts and changes in directions making it even more difficult for firefighters to control the blaze.
A 'Special Inquiry Into the January 2016 Waroona Fire' was held by the Western Australian Government, headed by Euan Ferguson. Its 264-page report was released on 29 April 2016.March
On 14 March, one townhouse and 12 hectares (30 acres) of parkland were destroyed by a fire that prompted evacuations at Edith Cowan University and damaged facilities at university situated in the City of Joondalup. A camper who had been lodging near Grassbird Avenue in Lake Joondalup Nature Reserve was charged for lighting the fire, allegedly to clear scrub near his camp site.
