Where to Start — the System or the Function?
How the V-model Clarifies Effective Computer Security
Taronga Zoo Sydney, Australia
There's nothing quite like the unique mix of native Australian wildlife and exotic animals set against the spectacular backdrop of the Sydney Opera House and the Harbour Bridge.
An End in the Barossa Valley, Australia
We traded the wind and the broken jetties for the stillness of the valley. Ending the journey here, among the ancient vines and stone cottages, feels like a soft landing after the rugged coast. The air is warmer, the light is golden, and the only crashing waves are those stirred willingly in a glass of Shiraz.
Stormy Fleurieu Peninsula, Australia
The wind hits different here on the Fleurieu. It whips across the gulf, bending the scrub and battering the coastline. The last time I stood on this coast 30 years ago, these jetties still reached out into the water. Returning now, they have been reclaimed by the sea, reduced to skeletal pylons by the relentless waves.
Inland Through Langhorne Creek, Australia
Turning the wheel away from the coast, we headed inland. The salt spray was replaced by the dusty greens of Langhorne Creek, a landscape of river red gums amongst the vineyards. But this was just a quiet pause before the final push towards the end of the Coorong.
Mouth of the Murray, Australia
The silence of the Coorong and the flow of the Murray River both die here. At this strange, significant convergence, the Southern Ocean at the end of the world finally swallows the fresh water that brings bounty to the interior and the endless shore of the Coorong.
Endless Coorong, Australia
Leaving the vertical drama of the cliffs behind, the world suddenly flattened out. There is raw isolation here. The Coorong is a stretch of South Australia that refuses to be tamed. Nearly 200km of scrub and saltwater lagoons separating the highway from the ocean, creating a landscape that feels infinite and untouched. It’s just the wind, the birds, and the endless road ahead.
Broken Coast at the End of the World, Australia
We arrived at the limestone edge where the continent crumbles into the Southern Ocean. Standing before the (less-than) 12 Apostles, the separation between land and ocean feels absolute. A hard-boiled wonderland of jagged cliffs meeting quiet solitude at the end of the world among lost shadows and relentless tides.
Sheltering at Maits Rest, Australia
We needed a break from the sun, so we stopped at Maits Rest to escape the heat. It feels like a different world down here—quiet, green, and wonderfully cool. The path loops through some massive trees that have been here for centuries.
Rounding the Twist to Aireys Inlet, Australia
You walk up to the lighthouse trying to act like a responsible adult. But, deep down, you are absolutely terrified that if you touch the wrong railing you’re going to be forced to finish the trip without your pants... Have you ever, ever felt like this?
Starting The Way at Apollo Bay, Australia
Starting the drive along the Great Ocean Road, on our way to Adelaide. The winding cliffs and wildlife set the tone for a lovely ride, leading us to our first stop for the night at Apollo Bay.
