It's too blurry to see what year this was, but we're currently taught (in Australia) not to do the Heimlich manoeuvre. Also that if you're doing CPR alone don't bother with the breaths, the chest compressions are more important - only do breaths with a second person so you can keep compressions going uninterrupted.
The poster's 2014. And yeah, Oz does seem to advise against abdominal thrusts (Heimlich), instead recommending chest thrusts. However, the US and European agencies recommend back slaps/coughing and then the Heimlich.
Also yeah, breathing in CPR doesn't really show benefits that outweigh lost time, so probably just compress.

I took a class last year that said this. It was "Shock and Compress." The compressions are doing more good than worrying about breaths. And delegate someone to find an AED.
It felt a little silly taking that class given that I work for a health org, and I'm fully remote. The odds of my needing to know if seem pretty low, but you never know when it might be important.
I know a family where they all took CPR lessons after grandpa had a cardiac event at Christmas and the 14 yo granddaughter was the only one who knew CPR due to a babysitting course she took over the summer.
Sure, EMTs can walk you through the basics over the phone until an ambulance gets there, but that's much better as a reminder than a initial lesson.
