Wall completely lost control of it opposite the party house.
A man was sleeping in a car outside the party and another man had just opened the door when Wall's vehicle bore down on them. The man leapt on to the roof of the parked vehicle as Wall's car passed within 1m of it before bringing down live power wires, snapping the pole off, and then slamming into the house.
Wall and his two young passengers escaped with only minor cuts and bruises.
Lawyer Vicki Walsh said it was a case of "a bad thing happening to an otherwise good young man".
Wall was a "person of some integrity" who had not "ducked and dived his responsibilities" and had shown genuine remorse.
Judge Noel Walsh said Wall was lucky he had not killed or been killed.
"Your driving was reckless. A quick thought that rushes to my head is 'what if there had been a young kid on the road?' You and others are lucky to be alive."
