Road transport electrification presents a once in a century opportunity to address the user-pays element (currently petrol/ diesel tax) that contributes about half of the direct costs of road spending (including maintenance, administration, expansion, enforcement)

Brewed in Thailand? What is going on… I’m guessing some tax dodge, how can it be more economic that exporting the ligit Pinoy article? As it happens tastes pretty much right, great lager with a bit more of a hit than I want or can handle these days, but great memories

I’m not sure how many people have this frame of reference (I guess not many). from a combination of family friends and mentors in the building trades, working with them on volunteer projects in my teens, (late 90s), and self-managed flat renos 2007-2017, and having a trade…

The Productivity Commission looked at this in 2025 but failed to make any concrete recommendations on what I think is the biggest problem: culture and training. The gap is too big for apprenticeships to be economic. pc.gov.au/inquiries-and-rese…

We need to rediscover the post-guild Victorian era formalisation of culture, training and practices in institutions to respond to what is an obvious market failure. Related thread: nitter.cf/roodave/status/1911374…

Interesting how this "small government" mega trend (defunding and privatisation of formerly centralised trade schools/ TAFE and competency management) has panned out. In principle, it sounded plausible. However without...

One reason politics used to be much more sensible is most politicians (regardless of party) had shared experiences of working very hard in tough jobs or fighting for Australia or both. Deteriorated from 1990s with rise of a frivolous “political” class-who today drive us all mad.

This graph embodies a profound group of policy failures on (excessive) migration, high income tax, high education costs, and collapsed/ defective trade capability and training institutions, feeding collapsing productivity and rocketing costs
ABS 2025 birth data out today. Birth rates are still falling, and Sydney is down to 1.38. In 2013 it was 1.85!

When I read my first Tom Clancy novel I thought what most dated it, tied it to the ’90s, was its confidence—the belief in experts, the trust in institutions, the faith in technology. I wrote a whole essay about it, I found it so striking. These days, I think what most dates Clancy is how many of his characters are empowered with real responsibility in their early thirties.

In NSW our government has excluded batteries from participating in the next 1.5GW of firming. In Germany batteries don’t win in the tender… Batteries can’t replace dispatchable fuels. They’re an ‘and also’. nitter.cf/footnotesguy/status/21…
A win for fossil gas. Not a single battery storage project was able to win capacity auction in Germany. Gas power plants won instead. In theory these are marketed as "hydrogen ready", but there are no specs and penalties in contracts which would make it viable.

It has never been delightful, but the current state of the Sydney Town Hall forecourt to station entry is just vile. Graffiti vandalism, urine, grime, (discarded?) possessions of the homeless. What a gateway for the civic centre of Australia’s biggest city

As if David Jones selling its stores in the 2010s wasn’t a bad enough sign, Woolworths selling it to private equity was surely the end of the road. It exists only as legacy brand. The heart and soul: live pianists, choirs, luxury food items, even Xmas displays long gone

Sydney has quite a lot of retail diversity in the CBD, I still shop at Myers there. Brisbane won’t look good after this. Myers gone, Myer centre and wintergarden sick. DJs leaving really bad for Queen St retail

Every time I see an image of napoleon i am reminded of a time I was out with a French girl in London c2007, after a few drinks, walking through Trafalgar Square (her first time) she looked up at the column and said “ah oui, Napoleon!” and I didn’t have the guts to explain

Australia’s first flag (or the first flag representing Australia), the Bowman Flag bore Nelson’s words “England expects every man will do his duty”. Sorry Nelson, I fucked up
