NSW batteries have now out-generated the entire gas fleet: 1,028 GWh discharged by the end of September, against 514 GWh from open-cycle gas and 161 GWh from combined-cycle. Same in Victoria. NEM-wide battery discharging out generating gas (both) for this year.

New South Wales battery discharge reached 1,028 GWh by the end of September 2026, against 161 GWh from combined-cycle gas and 514 GWh from open-cycle gas over the same period. The chart plots cumulative generation by fuel type through the year, so the point where the battery line crosses both gas technologies is visible.

Heading to be strongest on record. The 2026 El Niño has climbed 4.18°C in twenty months, from a La Niña low of −1.46°C to +2.72°C.

The relative Niño 3.4 index stood at +2.72°C on 27 September 2026, having risen 4.18°C in twenty months from a La Niña low of −1.46°C. The chart places that trajectory against all 28 events declared since 1902, aligned so each sits at the same point in its own calendar; the current reading is above 1902–03's previous record of +2.65°C."

Sydney hit 32.7°C on 21 September, against a 20.8°C average for the date. Observatory Hill has recorded daily maximums since 1859; years since 2000 crowd the upper half of that 167-year range.

Sydney Observatory Hill reached 32.7°C on 21 September 2026, against a long-run mean of 20.8°C for that date. The chart plots daily maximum temperature by year since 1859, with the mean and the 20-80 and 5-95 percentile bands, so the 2026 trace can be read against 167 years of observations.

Australia now has fewer than two working-age adults per dependant, at 1.9 — about 6.5 in every 10 people are of working age, against 6.8 at the 2008 peak. Old-age dependants equal youth for the first time on record.

Australia had 1.9 working-age adults for every child or person over 65 in March 2026 — about 6.5 in every 10 people of working age — down from a peak of 2.1 in 2008. The chart plots that support ratio by state and territory, from the Northern Territory at 2.4 to Tasmania at 1.6.

Fast and early, some El Niño take a while to get going - this one isn't.

As of 30 August 2026, the Relative Niño 3.4 index stands at +2.45°C, more than double the Australian Bureau of Meteorology's (BOM) +0.8°C El Niño declaration threshold. The current episode is measured from a La Niña low of −1.46°C on 2 February 2025, making the total rise 3.91°C over twenty months. The chart places that trajectory against every BOM-declared event since 1902, aligned so each event sits at the same point in its own calendar.

The 2026 El Nino is coming fast and early. No event has reached this high from a low in 19 months. On a different trajectory. #elnino #climate

As of 26 July 2026, the Relative Niño 3.4 index stands at +1.94°C — more than double the Australian Bureau of Meteorology's (BOM) +0.8°C El Niño declaration threshold, and 3.21°C above the La Niña low of January 2025 from which the current episode is measured. Nineteen months into that rise, 2026 is level with 1902–03, the highest any trajectory has reached at this point in its calendar. Of the 25 events in the record with a comparable reading at 19 months, none is above it.

In New South Wales, cumulative battery discharge reached 501 GWh in the first six months of 2026 — already more than the 282 GWh discharged across the whole of 2025, with almost half the year still to run.

$In New South Wales, cumulative battery discharge reached 501 GWh in the first six months of 2026 — already more than the 282 GWh discharged across the whole of 2025, with almost half the year still to run. Battery discharge has also overtaken both gas technologies it is compared against over the same year-to-date window: 133 GWh for combined-cycle gas turbines (CCGT) and 391 GWh for open-cycle gas turbines (OCGT). A year earlier, at the equivalent point in 2025, battery output was a fraction of either gas technology's — this shift emerged within 2026 itself, not as a gradual multi-year trend.$
