Thanks for your replies.
We took the car in yesterday to be looked at and was told that it wasn't an oil leak but wax. It seems that Kia Korea put wax on the engines so they won't become rusty due to them arriving in Australia by slow boat

.
When you start driving them the engine heats up and melts the wax. The mechanics cleaned off all the wax that was left, tightened up some bolts around the sump and sent us home.
Anyway, sure enough this morning we have another puddle in the garage and this wax sure does look and smell a lot like oil. What's the saying ... if it looks like a duck and walks like a duck then ...
So, 'Candy Carnival' (that's the car's name) is off for another visit to a different dealership and she's only done 500 klms.
I'll keep you posted.
Cheers,
Jacqui
PS. Esses - are you an Aussie, if so who serviced yours?
