My brother was off his L's and just onto his P's (by about 2 - 4 weeks) and drove all the way to Newcastle from Adelaide.
It was a KE70 with about 100,000KM on it. Before he left I changed all the cooling system, got a full service, changed the rear shocks (had a leak) and got all the brakes checked.
He said it went absolutely great and couldn't of asked for better :(
So I reckon you should be fine :)
