After eight years in the US, Nick Bryant returned to Australia to find a country that had retained many of its finest qualities. But it had also turned in on itself and become a more fractured nation.
It was the final full day of our summer holiday - January is the August of the southern hemisphere - and our friend had returned to the beach, in the golden hour of the late afternoon, to capture a few last snapshots.
By then, the sands had largely emptied. The sea looked too rough to swim in. But over the crash of the incoming waves, she could hear the anguished cries of a swimmer out at sea, who was obviously caught in a rip tide.
The woman looked like she was about to be swallowed by the swirling currents. But the closest lifeguard on duty was a mile away. So my friend called her husband on the phone - I was with him at the time - and told him to hurry down with his surfboard.
Not for one moment did he hesitate. He raced to the shore in what seemed like a flash. Then out he paddled, into the cauldron of a churning sea, to pluck the stranded woman from the ocean.
In my naiveté, I thought that the moment he pulled her onto his surfboard was the endpoint of the drama. But in many ways his struggle was only just beginning. Now he had to get back to dry land, hoping to catch a set of waves that would return them both to the shore. This task was made all the more treacherous by a swell that threatened to hurl them against the rocks.
As I watched from the clifftop, where I had stayed behind with our young kids, I could see the narrowness of the channel he was aiming for. I could also tell he was tiring. By now, there were more people on the beach, but if any of them ventured into the water without a buoyancy aid, they, too, would be swept out to sea.
Some were locals who knew the history of this bay on the Central Coast of New South Wales. Only last October, a man had drowned here after coming off his surfboard and being thrown against the rocks.
My friend and the woman were in the water for 15 minutes. It was a frighteningly long battle. But finally he caught a couple of helpful waves, which carried them to safety.
As they came ashore in a rocky inlet, my mate was ready to cop what he later described as "a serious cheese grater shredding" but they emerged from the water without a scratch. The swimmer was reunited with her boyfriend.
My friend was reunited with his wife. Then, without any fuss, he walked home with his surf board tucked under his arm, where he downed a cold beer and then cooked dinner on the barbecue.
Rarely have I witnessed such an impressive act of heroism. His steak was pretty good, too. But I'm telling this story not as an homage to Australian masculinity but because I think it speaks of a certain Australian mindset: a generosity of spirit, a calmness in the midst of crisis, a strong sense of community and togetherness.
They're qualities that both my friends displayed that afternoon, and their response was instantly recognisable as Australian.
Yet the country as a whole feels different than it did when we lived here eight years ago before we left to live in New York City. More fractured. More remote. More inward-looking.
For much of the pandemic, Covid restrictions have turned the lines on the map that divide the states and territories into rigid borders that could only be crossed with the grant of a permit - paperwork that was routinely denied.
Not since the founding of modern Australia, more than a hundred years ago, has the country been more geographically fragmented. Western Australia, whose borders are still shut, feels like it has declared independence. Queensland has also acted at times like a self-governing fiefdom. The premiers of the states have often governed more like prime ministers. Absent throughout has been a sense of Australian nationhood.
