Article gives you the idea that it would be taking pax to Rottnest Island (a popular tourist destination) but it's only registered as a 'recreational' so the only ppl going to Rottnest would be pilots themselves or a non-paying pax.

Payload is 200kg so that is basically two people and one suitcase.

30 minutes reserve might be enough for short hops but I've just finished reading various articles written over the years by Richard Collins (who writes a lot about safety) and he states that he always had a hard rule of a one hour reserve.

Still, the operating costs are crazy cheap. If they made a plane that had 3 hours range (2 hrs flying, 1 hr reserve) at 100+ knots with more payload, I'd be interested.
