Mate you did and an awesome how to it is, but the tradeflame brand bottles from Bunnings, like the barleyman kit, take a different size reg to the oxyturbo bottles.
Have a look at my adventures in getting an oxygen set up organised. In short I am using one of those new cylinders now. See posts 5 and 15.

The cylinder at bunnings was 49.88. The reg which I bought by mistake which I put up in post five from this thread fits. So not sure about the tradelink ones. But my Tuesco reg was too big for the thread on this new cylinder. The new cylinder is 136 grams, so same price and size as the Bromic ones.
Just as a bit of a heads up. I went down to bunnings today to replace my oxyturbo bottle on the aeration kit I coupled together six months back. Turns out at least at the moment bunnings is selling this new type of cylinder with a smaller thread than the tuesco reg I ended up with. That being...
Not real close to the Northern beaches but an option.

Yeah when I came back from the US two years ago I had the prints outs from daff with me. The Aquis person on the line didn't really know what the go was but was happy to look it up and tick it off without too much too much drama. Put it down on your incoming pax card and no worries.
Looks like a bank of these, or ones very like them.
