I recognise the Guringai (Ku-ring-gai) language group of the Garigal Aboriginal clan as the Traditional Owners and holders of knowledge of the place where I live and work.

We DO have bigger kangaroos than anywhere else.
In case you think only Australia has kangaroos, there are also kangaroos in New Guinea (PNG and Indonesia), but these are tree kangaroos.

Eyre Highway across the Nullarbor Plain has the longest straight stretch of road in the world, measuring 146 kilometers (about 91 miles) without a bend. I’ve not driven this road, but my sister has.

I remember both the light lamp connection for a drop light from the ceiling, but also the flat plug into the iron, typically for a hot water jug.
Common in all Australians home even today for hot water for your cup or pot of tea, but with a modern plug.

I’m an IT contractor and I was out of work for 12 months until recently. Don’t let it get to you, eventually something will turn up. It’s not you, it’s them. Just keep swimming.

Indigenous communities around the world would disagree. The remote Aboriginal communities in Australia have some of the worst living conditions and health / education in the world. A major income for these communities is their distinctive art. Knock-off copies of their style undermine this.

Australian cattle dogs come in two colours - blue cattle dogs and red cattle dogs. They are not different breeds - you can often get a mixed littler of blues and reds. Blue becomes bluey. There is even a cartoon series

Starlink is the 21st century equivalent of hydraulic mining in the 19th. Great profits to be made, but not caring about the impacts to others.

For comparison, here is a tram stop in the Sydney city. The trams are tap on / tap off, so no gates required.

Penguins!!
But which? The Emperor Penguin is the toughest bird on the planet, walking up to 120km in Antartica in the middle of winter. Perhaps the Galapagos Penguin, the only penguin found in the northern hemisphere. But probably the Fairy Penguin, as they are local to me in Sydney.
