Hi @Quincy
Great question as I think a lot of hosts may be doing this outside the scope of what is actually permitted. As far as insurance goes I believe you would have to notify your carrier that you are conducting business with your vehicle especially if you are getting paid.
Here is what we would have to do for QLD:
"Services such as tourist transfer services, accommodation transfer services, passenger services, bus services, etc. come under the general service category of the Queensland Transport and Main Roads department."

I am of the opinion that in a tourist town it is nice to see the influx of tourist dollars shared amoung the residents. For this reason, we would not infringe on the business of the transport industry.
We do pass along all the info to guests for the different transport options so they can easily phone and arrange their shuttles.
For a country that has no social security number system and had no photo on drivers licences late into the 80's they sure are on top of a lot of random regulations. Also the reason why we cannot leave any breakfast provisions for guests.
Perhaps it is less regulated in other areas of the globe, Lisa
