There is a particular kind of arithmetic that takes over your brain the moment a doctor delivers a serious diagnosis. You are not really listening to the words anymore. You are calculating: ages, years, percentages, the number of summers you may or may not have left. I know this because I have been doing it myself, sitting in a clinic chair, watching a nurse search for a cooperative vein while my mind races through numbers I cannot quite make add up.
My diagnosis is melanoma. And even as I process what that means for me personally, I keep returning to a broader question: how did I get here, when Australia has spent four decades telling us exactly how not to?
The campaign that changed a culture
"Slip, Slop, Slap" was not just a catchy jingle featuring an animated seagull. Launched by the Cancer Council Australia in 1981, it became one of the most effective public health interventions this country has ever produced. Before it, Australians wore their tans like badges of vitality. Afterwards, at least some of us started reaching for the sunscreen before we reached for the beach towel. Research has consistently credited the campaign with shifting community attitudes and, over time, contributing to measurable reductions in skin cancer rates among younger Australians who grew up under its influence.
The numbers tell a story worth sitting with. Australia and New Zealand have the highest rates of melanoma in the world, a grim distinction that reflects both our geography and a colonial culture that arrived without the skin pigmentation suited to this continent's ultraviolet intensity. According to the Australian Institute of Health and Welfare, melanoma is the third most common cancer diagnosed in Australia, with around 16,000 new cases recorded each year. About 1,800 Australians die from it annually.
What the slogan could not reach
Here is where the maths gets complicated. The campaign worked, and yet here I am. And I am not unusual. Melanoma rates among older Australians, particularly men, remain stubbornly high. Part of this reflects the long lag between sun damage and its consequences. The burns I collected as a child in the 1970s and 80s, long before Sid Seagull told me to slip on a shirt, are writing themselves into my skin decades later. Prevention campaigns are always fighting yesterday's sun exposure as much as today's.
There is also an equity dimension that public health messaging has historically struggled with. Outdoor workers, regional and rural Australians, and people from lower socioeconomic backgrounds tend to have both higher sun exposure and lower rates of skin checks. Cancer Council research has repeatedly shown that awareness of sun safety does not automatically translate into protective behaviour, particularly among men, who are diagnosed with melanoma at roughly twice the rate of women.
There is a fair argument that we have over-invested in broad awareness and under-invested in access. Knowing you should check your skin is not the same as being able to afford a dermatologist, or having one within two hours of where you live.
Early detection and the treatment frontier
The good news, and there is some, is that treatment has genuinely transformed in recent years. Immunotherapy and targeted therapies have dramatically improved survival rates for patients with advanced melanoma compared with even a decade ago. The Therapeutic Goods Administration has approved a range of newer treatments that were simply unavailable to patients in earlier generations. For those caught early, the prognosis is often excellent. For those caught late, the odds narrow quickly. Which is why early detection is not a talking point; it is the ballgame.
As I sit here doing my unwanted arithmetic, I find myself less interested in assigning blame and more interested in what actually changes outcomes. The slip, slop, slap instinct was correct: shifting behaviour at a population level is possible, and Australia proved it. The harder question is whether we can now apply that same ambition to the gaps that remain, including access to skin checks, GP bulk billing rates that make preventive care viable, and public campaigns targeted at the demographics most at risk rather than the ones most likely to already be paying attention.
A diagnosis has a way of concentrating the mind on what matters and what doesn't. What matters, it turns out, is not any single campaign or policy, but the whole system working together: awareness, access, early detection, and treatment. We have built parts of that system well. Other parts still need work. And for those of us currently in the chair watching the nurse find a vein, the gap between "good enough" and "good" is not abstract at all.
