At least in WA, United States, the borders aren't closed (except with Canada).
CO2 is not uniformly distributed in the atmosphere. You might want to take several readings. In some rooms you might see a reading as high as 1000. Outdoors, depending on location, you could very well see variable readings, depending on how close to some fire or some thick vegetation you are. You should take multiple readings throughout the year also, since actively growing vegetation can change the value. That's all seasonal.

In my mind, the two single biggest factors are:
1) outdoors vs. indoors. Walls prevent airflow and CO2 from indoor sources accumulates indoors and will never be related to outdoor CO2 levels. Personally I think you erred somewhat in your wording by implying that 1,000 ppm was some sort of upper limit. Presuming his CO2 meter is accurate he should find indoor settings above 1,000 rather easily.
2) elevation. CO2 is a heavy molecule. Most of Perth is close to sea level. My guess is that as soon as duncan gets an opportunity to check CO2 in a rocky, outdoor mountainous region at elevation ... the readings will plummet big time.
I actually have great expectations. I have a particular agenda. I don't mean to hype but this will actually be HUGE and I thoroughly plan on broadcasting this all over the internet. This is what we're looking at:
Our current "conventional wisdom" which is "what we know" of earth's atmosphere is that it is currently uniform at 412 ppm, right? (see attached)
What I expect that we will be learning is that the earth's atmosphere is just under 300 ppm at sea level (not necessarily uniformly distributed) ... that
it drops to close to 100 ppm at a couple of kilometers and then drops off to below his meter's tolerance at a few more kilometers, i.e. our Wikipedia-propogated notion that earth's CO2 percentage is 0.042% CO2 is going to suffer a hit. I'm going to draw up the "Duncan Model" (I was going to call it the "IBDaModel" but that wouldn't be right) based on duncan's measurements, with elevation being the most important, and I'm betting that my calculations will show an earth's global atmospheric CO2 percentage as being much closer to 0.013% than 0.0412%.
It will be glorious. duncan, no pressure ... it's only the future of earth science that rests on your shoulders. No pressure.
Did I mention that elevation is key?

I'm fairly certain that the CO2 readings are going to be much lower the Mauna Loa. Active volcano, an little vegetation. Seems to be the number one location, least it gets mentioned most.

I hope you are not surprised. Soon you will be making them all look foolish.

If you wouldn't mind, let's standardize on elevations used here.
Wherever you measure, try to pinpoint the location on this topographic map and we'll use that as our "official" elevation ... however if you also know of second elevation measure, note it for reference.

Really? In Australia the hot spot seems to be in Victoria.
Maybe what benefits Aussies like yourself is that you live on an island and it's not Hawai'i? The Outback might be a good steak house but why go to Australia for that when we have an Outback here?
I mean you guys can't even drive to Alice Springs without going 4 wheeling. Please don't make Australians seem like idiots. The country has a lot of remote locations and that's different than living in the US.

And on a historical note, when AC/DC was driving from Adelaide to Perth across the Nullarbor Plain, they wrote the song Highway to Hell about the road leading out of Perth to a bar where many rock bands played.
Still, I like INXS and Midnight Oil.
