15 Amp to 10 Amp

Hey all,

I'm about to head to Broome to collect a campervan we have just purchased. It is a last-minute trip and we intend to drive it back to Perth over two to three days.

The camper doesn't have shore power and i was wondering if it was ok to plug a 10 Amp chord into the 15 Amp points at caravan parks. I know it can be done safely but had heard it was frowned upon by some park owners.

Thanks
