A middle-aged white man in a black t-shirt stands in front of some tropical tree or other, smiling, with his hands clasped behind his back. His hair is brown, as is his beard. He wears spectacles . The t-shirt has a green print in the style of, and indeed taken from, an old video game called Oregon Trail. It shows a covered wagon and the text: You Have Died of Dysentery.

People who are agog at the BoM website rebuild costing more than they expect should remember that every IT project goes well over budget, especially if a consultancy is involved. Public or private sector, it doesn't matter.

Women and older career switchers are generally not even exposed to red team as an option of interest that they’d be good at using socialized skills, which is kinda crazy when the most ignored people in society who can pretty much walk in anywhere are older women. Instead we portray it like esports.

"Creating and publishing software under an open source license is an act of contribution to the digital commons. Finding and publishing information about security issues in that software is also an act of contribution to the same commons." Maybe, but these contributions are not of equal value.

Fun* fact: in Australia, over 87% of the people who have data exposed in a data breach do so because it was in the ~3 very large data breaches we have each year. (On average, since 2018)

Wow, Services Australia spent three quarters of a million in legal fees fighting a losing FOI fight against @daedalus.eigenmagic.com
Topic: Robodebt Case Legal Fees
Question reference number: IQ25-000016
Asked By: Senator Jacqui Lambie
Type of question: Spoken. Hansard Page/s: 9
Date set by the committee for the return of answer: 24 October 2025
Question:
Senator Lambie: Services Australia, you lost a Robodebt case against Mr Warren before the full
court. I'm just wondering what your legal costs for both Administrative Review Tribunal and the
Federal Court were? I’m gathering it's about half a million and I’m being conservative. Do you
know what the costs were?
Mr Higgins: I'd have to take that on notice, Senator. I don’t have that detail with me.
Answer:
$776,739.02 including GST (where applicable) in relation to AAT, Federal Court and ART.

I don't want public servants who don't understand how emails work and politicians who use this to tell pathetic lies about the FOI system regulating the use of the internet. The standard of public representation in communications policy is through the floor, and it's been Labor's level for decades.
Internal chat logs from February, released to transparency website Right to Know under freedom-of-information law, revealed panic setting in at the online safety regulator when the emails using this form began.

“[They] have created a new tool which has been facilitating applicants sending in a new FoI request every five minutes or so (50 FoIs since 1pm),” the 5.45pm message stated on 8 February.

“I am concerned that emails flowing in every few minutes may jam something and prevent work … I suppose or mailboxes are built to sustain that quantum but I wanted to check and make sure nothing needed to be done, just in case.”

An anonymised IT staffer at eSafety dryly responded: “If it’s one email every five minutes that isn’t a concern at all from an IT perspective.”

“I am concerned at the current pace, the emails might jam something. I am not sure how much data these mailboxes are built to hold,” the first staffer replied.

Good roundtable discussion at #TFDx about Microsoft Sentinel and its potential. Seems a little early and more investigation will be needed before firms choose to make a strategic investment in Sentinel as their single point of success. It could be quite useful.
