While removing tiles during renovations at the Lenna of Hobart Hotel, Brian Cooper came across something hidden in the walls.

He pulled out a newspaper that was over 50 years old, but quickly realised this was no ordinary paper.

"I wasn't too sure what it was, I thought it was a porno book really," Mr Cooper said.

The 1973 erotic newspaper by Ribald in Sydney is reminiscent of a time capsule, revealing a part of Australian history almost forgotten.

The yellowed pages feature satire articles, from a flasher with "duplicated genitalia", to a male wrestler held at gunpoint for sex.

Throughout, there are nude models, erotic comics, personal advertisements and even a sex quiz.

It also depicts photos and articles of homosexuality in a time when that was criminalised in some states and territories.

How did it get there?

Cameron Clark's family owns the hotel, and Mr Cooper said the newspaper may have made its way there during renovations of the main mansion in 1974.

"It would have been some of the workers that were doing the renovations on it, without a doubt," he said.

The original 1874-built sandstone mansion is listed on the National Trust, and its walls have hosted famous guests, including Andrew Mountbatten-Windsor (the former Prince Andrew) with Sarah Ferguson, and members of the band Midnight Oil.

"[The newspaper] will probably be put into one of the scrapbooks or museum areas that we've got within the hotel," Mr Clark said.

"It's a genuine piece of history.

"But it's probably not everyone's cup of tea, so whether it will be on public display or not, I'm not sure."

Satire, sex and alternative press

There were several erotic and satirical newspapers in Australia in the 1960s and 70s, including Ribald, Oz, Squire, and the popular Kings Cross Whisper.

In an interview with the ABC in 1971, editor of the Kings Cross Whisper Terry Blake said it was the type of journalism people wanted compared to typical news publications.

"The degree of professionalism, the degree of well-written copy and the realistic appraisal of the world as it is, [is] far more evident in the Whisper," he said.

Some of the headlines featured in the Kings Cross Whisper during its publication between 1964 to the mid-1970s included:

Everything in Australia banned

Opera House to be a hamburger joint

Victoria plans new body to plan new plan

Poker machines ban people

Pop group sings in tune

So, who were the writers behind these parody articles?

Mr Blake said "some of the best journalists in Australia".

In an interview with The Sydney Morning Herald, co-creator of the Kings Cross Whisper Max Cullen said well-regarded journalists adopted fake names to write for them.

Battle of censorship

As you can imagine, some state and territory governments at the time were not the biggest fans of these publications.

The editor of another erotic publication, called Squire, said in an interview that he received "hints" of government objection.

"We've only ever had trouble with Victoria, none of the other states have made any fuss at all," Jack de Lissa told the ABC in 1967.

There was a legal risk involved with publishing erotic content, with the editor of the Oz, Richard Walsh, going behind bars during the 1960s, charged with issuing an obscene publication.

Some publications were also ripped off street stands in Perth by police, according to a Canberra Times article in 1973.

"Plain-clothes police raided a city bookstall today and seized sex publications valued at $500," it read.

"They took girlie magazines and copies of the eastern states publications Bawdy and Ribald."

The copy of the uncovered Ribald newspaper in Hobart shines a light on a time in Australia's media history where sexuality was scandalised.

Australians are told every summer how hot it’s going to be.

But increasingly, the information we’re given bears little resemblance to the heat people are actually exposed to – and that disconnect is becoming dangerous.

This isn’t about climate denial or attacking science. It’s about using the right science for the right purpose, and recognising that the way we talk about heat has failed to keep pace with the conditions people now live in.

The temperature you’re told isn’t the heat you feel

When weather services report a maximum temperature – say 39 °C – many people reasonably assume that reflects what they’ll experience in their suburb, on their street, or in their home.

It doesn’t.

Official readings, such as those used by the Bureau of Meteorology, are taken under carefully controlled conditions:

• In shade
• Well ventilated
• Away from roads, buildings, cars, and concrete
• Designed for long-term consistency, not human exposure

These measurements are excellent for climate records and historical comparison. They are not designed to describe the heat load people actually endure in built-up environments.

In suburbs dominated by asphalt, brick, concrete, and dark roofs, real-world conditions can be 8–15 °C hotter than the official figure once radiant heat and stored heat are accounted for.

Yet this gap is rarely explained clearly to the public.

Why this matters more than most people realise

Heat doesn’t kill dramatically. It kills quietly.

People collapse days into heatwaves, not minutes into them. They underestimate risk because the numbers they’re given don’t match what their bodies – and their homes – are experiencing.

When a forecast says “Maximum 39° C”.

Many people hear:

• “Hot, but manageable”
• “I’ve handled this before”
• “It’ll cool down later”

But what they may actually be dealing with is:

• Street-level exposure equivalent to 45–50 °C
• Buildings that have absorbed heat all day
• Nights that don’t cool enough for the body to recover
• Cumulative heat stress across consecutive days

That mismatch delays protective action – and increases health risk, especially for older people, children, and those with chronic illness.

The missing piece: buildings don’t just get hot – they store heat

One of the most dangerous misconceptions about heat is the idea that air temperature alone determines comfort and safety.

It doesn’t.

What matters just as much is thermal mass – the ability of buildings and materials to absorb, store, and later release heat.

Brick, concrete, tiles, stone, and even plasterboard act like thermal batteries:

• They absorb heat throughout the day
• They continue releasing it long after the sun goes down
• They can keep indoor spaces hot even when outside air temperatures fall

This is why people often say, “It’s still hot inside even though it’s cooled down outside.”

They’re not imagining it. The house itself has become a heat source.

Why this changes how heatwaves should be managed

During short hot days, thermal mass can help.

During extended heatwaves, it becomes a liability.

If a building:

• Isn’t actively cooled early
• Isn’t shaded
• Has limited night purging
• Faces repeated hot days without a full cool-down

Then each day adds heat to the structure, not just the air.

By day three or four, people aren’t cooling a room – they’re trying to cool walls, floors, furniture, and ceilings that are already heat-soaked.

This is why:

• Overnight temperatures matter so much
• Consecutive days are far more dangerous than single extremes
• Homes that “cope fine” on day one can become unsafe by day four

Official forecasts rarely communicate this compounding effect.

Why “it’ll cool overnight” is no longer a safe assumption

In many heatwaves, overnight minimums stay above 22–25 °C.

That means:

• Buildings don’t fully release stored heat
• The body doesn’t fully recover
• The next day starts hotter than the last

This is one of the strongest predictors of heat-related illness and death – yet overnight risk is still downplayed compared to daytime maxima.

A house that never truly cools is not a safe refuge, even if it has air-conditioning.

“Your car thermometer is wrong” … not really

People are often told that car temperature readings are inaccurate and should be ignored.

That’s misleading.

Car sensors measure local, radiative heat exposure. They are unsuitable for climate records, but they often reflect the heat stress people actually experience at street level.

Dismissing these readings without explanation teaches people to distrust their own perception – exactly when they should be paying attention.

The data already exists – the communication doesn’t

Australia already has:

• Urban heat-island research
• Apparent temperature and heat-stress modelling
• Excess mortality data from heatwaves
• Satellite land-surface temperature data
• Health department heat-risk thresholds

What’s missing is a public-facing translation layer.

The system answers, “What is the regional reference temperature?”

People need answers to:

• How hot will my surroundings get?
• Will my house store this heat?
• Will it cool enough overnight to recover?
• How many days will this persist?
• What actions matter before the heat peaks?

Those questions are largely left to individuals to figure out – often too late.

What safer heat information would look like

We don’t need new technology. We need honest framing.

Imagine forecasts that said:

“Although the official maximum is 39 °C, built-up suburbs may experience conditions equivalent to 47–50 °C. Buildings will absorb heat throughout the day and may remain hot overnight. Actively cool living spaces early, reduce heat storage, and plan for limited overnight relief.”

That information already exists. It simply isn’t prioritised.

This isn’t alarmism – it’s accuracy

The goal isn’t to frighten people.

It’s to give them relevant, actionable information.

Australians are resourceful. When people understand how heat actually behaves – in streets, in buildings, over multiple days – they adapt.

What they can’t do is respond to danger that’s been averaged away.

As extreme heat becomes more frequent and persistent, continuing to rely on technically correct but exposure-blind temperature reporting isn’t just outdated.

It’s unsafe.
