His lawyer Mark Dollimore said Flintoft's explanation was that he was "burnt out" from his work as a builder, and from not having seen his daughter in some time.
"It was an accumulation of matters that led to the meltdown," Dollimore said.
In answer to a question from Judge Jo Rielly about why Flintoft had said what he did, Dollimore said he knew it was frivolous, but that it had occurred as a result of "banter with the police".
"They were getting on well and somehow it ended up in the summary," Dollimore said.
Flintoft was convicted and fined $1000, and disqualified from driving for 28 days under a alcohol interlock disqualification order.
Judge Rielly told him it did not mean he could simply drive again after 28 days, but that he remained disqualified until he applied for, and obtained an alcohol interlock licence.
"It's unfortunate you're before the court because you haven't been for almost 25 years. This is your third or subsequent offence, but not for a long time.
"I do however have to treat this as more serious than if it was a first offence," Judge Rielly told Flintoft.
