Trains are good investment as population density rises. They are long-term investment. I remember the outrage when $100m was spent in Perth for North Line. Today that looks like nothing! Return amazing. abc.net.au/news/2026-10-26/l…

I have always said every company should have an ethical advisory board. Not just university research. Here is a great example of something that should have ethical oversight. arstechnica.com/tech-policy/…

WOW. A message that changes the mindset. Been a very up and down days as I progress into retirement. But getting messages like this makes it all worthwhile.

You know we were called "making a flood" of dentists. I would love to redo this data now, years later, but there was never a flood. We moved a little in terms of OECD, but no flood! Making the nation a better place is hard and has painful memories

I was going through some old papers. This is nearly a decade old. Through the early 2000's Australia carefully and smartly increased its dental education scale the first increase in 60 years! Corrected the course of a nation!

Got to love spring time.

The last while has been a pivot moment in life. I have been so lucky to be able to walk each day in some lovely quiet bushland to remain strong. Let's keep these spaces in our cities.

What an amazing career - retiring in December. We will miss Robyn Williams - a terrific science communicator!! Thank you. theguardian.com/media/2026/o…

Such a reflective place. And now the roses are coming. The terrific gardener was telling me he jots down names and goes and looks up the stories behind the war grave stone. Such respect.

Today - The return of Marc's public health quick takes. "Water, Please." I do hope its interesting and brings some knowledge. I am looking forward to getting going again.

What a wonderful verge garden I walked past yesterday. This brings such joy.

A question. Does "business" truly price all the inputs. Or, for the sake of profit, devalue/look for the lowest cost at the risk of variables that are not immediately impactful? Is that a core problem? Is that how we have got to where we are now?

Today. Technically first day of retirement. Very strange... Went down to work to have time with my friend and colleague of 25+ years. Then home for a little celebrate breakfast

When are we going to reflect on privatisation? theguardian.com/australia-ne…

Well. I can announce it formally. Marc has retired. That actually means time for new adventures, after a little rest and rejuvenation.

I just found another one!! They are everywhere. Have a good look around your streets
