Data from NTC's Light Vehicle Emissions Intensity 2025 Report. The data dashboard there contains lots more details including stats based on regions, fuel/powertrain type, market segment, and you can look up individual car models on page 9.

Curtailment, or why Australia can give everyone three hours of free solar power during the day

I annotated this chart to show the huge gap between the curtailed (wasted) renewable power at midday in Australia and the storage available to make use of it. Hence the recently announced Solar Sharer Scheme, which will give Australians three hours of free power in the middle of the day.

Former MP Kathryn Hay given suspended prison term for abuse of former husband

From the ABC news article - excerpts from the victim impact statement:

"The abuse has had long-lasting effects on my mental health," he wrote.

"I struggle to maintain existing relationships, let alone form new ones."

Mr Richardson said he had been diagnosed with post-traumatic stress disorder and described "overwhelming" panic attacks.

"The trauma continues to affect my daily functioning,"

The court also heard Hay was previously convicted of assaulting Mr Richardson, after a member of the public reportedly witnessed Hay slap her then-husband in a carpark and called the police.

Non-Monotonicity in Australian Preference Voting

Dylan Leigh — Wed, 18 Dec 2019 01:14:48 GMT

There are several methods of voting which allow voters to rank candidates in order of their preference, rather than just selecting a single desired candidate and then doing a single count (Plurality or "First Past the Post" voting). The system specifically used in Australian elections is "Instant-Runoff Voting" (IRV).

IRV is intended to allow for a variety of political parties of various sizes to flourish (unlike the famously two-party-dominated politics of the USA) as citizens who vote for a minor party as their first preference don't "waste" their vote; if their first preference is too obscure to get in, their vote goes to their second preference, and so on.

However, it is still possible for "vote-splitting" to have a negative effect on minor parties - in some cases, giving a candidate a higher preference can paradoxically cause them to lose, as they can be eliminated earlier.
