Every city thinks it knows its own reputation. Sydney's cosmopolitan, Melbourne never sleeps, Vegas is Vegas. Then you look at what people actually type into search engines, and the reputations fall apart.
We ranked cities across Australia, the United States and South Africa by tracked monthly search demand for hookups and casual sex — first by raw volume, then adjusted for population. The raw list looks how you'd expect. The per-person list does not.
By total searches, the big cities lead, more or less:
| Rank | City | Monthly searches |
|---|---|---|
| 1 | Melbourne | 2,190 |
| 2 | Adelaide | 1,930 |
| 3 | Sydney | 1,230 |
| 4 | Hobart | 1,130 |
| 5 | Perth | 1,010 |
| 5 | Canberra | 1,010 |
| 7 | Brisbane | 990 |
Already something's off. Adelaide — a quarter of Melbourne's size — sits within touching distance of it. Hobart, a city of 250,000, out-searches Perth. And Sydney, the biggest city in the country, limps in third at barely half Melbourne's number.
Now divide by population. Searches per 100,000 residents:
| Rank | City | Searches per 100k |
|---|---|---|
| 1 | Cairns | 494 |
| 2 | Hobart | 452 |
| 3 | Ballarat | 322 |
| 4 | Canberra | 215 |
| 5 | Darwin | 173 |
| 6 | Adelaide | 138 |
| 7 | Newcastle | 84 |
| — | Melbourne | 42 |
| — | Sydney | 23 |
Cairns. A tropical tourist town of 160,000 people searches for hookups at more than ten times Sydney's per-person rate. Hobart is right behind it. Ballarat — Ballarat! — triples Melbourne.
The pattern is unmissable: per person, Australia's casual dating demand lives in its small cities, and the gap isn't subtle. The polite theory is anonymity — in a big city you have options and crowds; in a smaller one, the internet is the discreet option. The less polite theory involves what there is to do in Cairns on a Tuesday night. The data declines to settle the argument.
Worth noting for the sceptics: Canberra at #4 per capita is the nation's capital quietly outpacing every mainland state capital. Public servants, we see you.
Raw volume:
| Rank | City | Monthly searches |
|---|---|---|
| 1 | San Diego | 2,150 |
| 2 | Houston | 1,890 |
| 3 | Spokane | 890 |
| 4 | Kansas City | 700 |
| 5 | Las Vegas | 580 |
| 6 | Long Island | 560 |
| 7 | Colorado Springs | 550 |
| 7 | Utah | 550 |
Per 100,000 residents:
| Rank | City | Searches per 100k |
|---|---|---|
| 1 | Spokane | 148 |
| 2 | Colorado Springs | 72 |
| 3 | San Diego | 65 |
| 4 | Fresno | 42 |
| 5 | Kansas City | 32 |
| 6 | Houston | 26 |
| 7 | Las Vegas | 25 |
Spokane, Washington — population 600,000, better known for lilacs than libido — searches for hookups at six times Las Vegas's per-person rate. Sit with that. The city whose entire global brand is "what happens here stays here" gets out-searched, per capita, by Spokane, Colorado Springs, and Fresno.
There's a straightforward explanation for Vegas, at least: people don't search for casual encounters in Vegas, they just have them — the city itself is the platform. The mid-size city pattern, though, matches Australia exactly. Spokane is America's Cairns.
Our South African tracking is younger and thinner, so treat this as a preview rather than a verdict — but the early numbers follow the same script:
| City | Monthly searches |
|---|---|
| Germiston | 650 |
| Soweto | 550 |
| Katlehong | 170 |
Notice what's missing: Johannesburg, Cape Town, Durban. The demand showing up first isn't in the postcard cities — it's in Germiston and Katlehong, exactly where the Australian and American patterns predict it would be. We'll expand ZA tracking and update this section in the next edition.
Per person, casual dating demand is inversely related to city size. Cairns beats Melbourne. Spokane beats Vegas. Germiston shows up before Johannesburg does. Three countries, one pattern, no exceptions in the current data.
Which raises a pleasant irony: the entire online dating industry markets itself to big cities, while the people searching hardest live everywhere else.
Every city in this index has its own local page — see who's actually nearby: Melbourne, Adelaide, Sydney, Hobart, Perth, Canberra, Brisbane, Cairns, Ballarat, Darwin, Newcastle · San Diego, Houston, Spokane, Kansas City, Las Vegas, Colorado Springs, Fresno, Orlando · Germiston, Soweto, Katlehong · or start at local hookups.
Search volumes are tracked monthly organic keyword data (SEMrush exports, July 2026) covering hookup and casual-sex related terms per city. Per-capita figures use publicly available metro/city population estimates from the Australian Bureau of Statistics, the US Census Bureau, and Stats SA. This reflects tracked keyword demand, not the totality of search behaviour — cities enter the index as tracking expands, which is why the UK and Ireland aren't ranked yet and South Africa is provisional. The index is refreshed quarterly; historical editions stay published so the movement is checkable. If a number changes, you'll see it change — we'd rather be caught being honest.
Which city searches for hookups the most?
By raw volume in our tracked data: Melbourne (Australia) and San Diego (US). Adjusted for population, it's Cairns and Spokane — smaller cities out-search big ones per person by wide margins.
Do big cities have more casual dating demand?
In total, yes; per person, emphatically no. Cairns's per-capita search rate is over ten times Sydney's, and Spokane's is roughly six times Las Vegas's.
How often is the Hookup Index updated?
Quarterly, with previous editions kept public.
