Question for Gasmate Hot Ozi owners

Hi all

Thanks to all who replied a few weeks ago about portable BBQ options. After much thought and research I decided to go with the Hot Ozi - a solid plate small round BBQ which sits on a pole directly onto the top of the gas bottle and acts as the hose.

Now though, I have a couple of questions for current Hot Ozi owners (or anyone else who can answer the first question)

1) The instructions clearly state it is to only be used with bottled PROPANE. Is the LPG we get a hardware stores/servos/caravan parks etc actually propane, is it just a difference in terminology between Australia and NZ (where they are made), or are they different fuels?

2) I anticipated a mild steel hotplate which I could burn lots of nice greasy fat onto and form a good protective barrier, only having to scrape off the excess and leave the fat on to protect it in between uses. However the surface is non-stick like most frying pans and you can't even use metal bbq tools on it. This is probably good for bacon/eggs/tomatoes etc, but not really the 'genuine' thing for bbqing t-bones/sausages etc. we pretty well could have gotten the same effect from a non-stick frypan on our 3 burner stove. How have other users found this non-stick surface and what do you do with it as far as cleaning etc.?

Thanks for your replies in advance.
