Cheers, I was wondering what a swampy was initially.
Just based on them creating humidity, swamp like if you will.

Yeah, I thought it would struggle big time, all our bedrooms were upstairs, no one needed to sleep downstairs at all during the summer.

Inside with the A/C going.
Anyone on here actually work outside?
I couldn’t imagine it in this heat.

I did look up to see what was the best way to use them and found the right sort of mix of having windows or sliding doors slightly ajar, made a huge difference when everyone else in the house adhered.

Meh. Had a small evap unit in our last pad. Had it serviced every so often so it was presumably operating as well as it could. It worked fine when the temp went up to the low 30s. Any higher and it merely took the edge off. There's only so far you can cool forty-something degree air by pumping it through water.

Yes, and no.
Hot dry outside air is drawn in by a fan through a wet cooling pad, this process takes the heat out of the air before being pumped into the building.
In dry climates, like ours, this also adds moisture to the air giving more comfort to the building occupants. ( Relative humidity of about 45% is good for most people ).
The cooling potential for evaporative coolers is dependent upon the difference between dry-bulb and wet-bulb temperatures. ( Dry-bulb is dry thermometer shielded from radiation and humidity and wet-bulb is a thermometer covered in a wet towel with air passing over it ).
Your cooler at home should reduce the outside air temperature to within 3-4°c of the wet-bulb temperature. If the difference between dry-bulb and wet-bulb is too high then the coolers ability to take the heat out of the dry air is reduced.
In essence the air being drawn in from outside is still being cooled and saturated but not enough to get the temperature closer to wet-bulb than dry-bulb, thus you "feel" like it isn't working, it is but not as well.
Evaporative air conditioners are shit. End of story
You get what you pay for.
refrigerated air conditioning is the only way to go in Australia

Rough numbers - refrigerated costs 3x as much per year to run and 2x as much to install, roughly.

and it makes you 10x more comfortable in this shit weather as opposed to a crappy evaporative. The only people who rate evaporative are those who don't have refrigerated.
