Luciani, 50, won the Formula 100 category at Corio Karting Complex, 20 years after winning his first national title at the same venue.

In winning the title, Luciani set a Australian Karting Association record, becoming the oldest competitor to win a national crown.

"I won my first Australian Championship there in Geelong in 1990 and in 2010 I decided to have another go and see if I could repeat history," Luciani said.

"It was a personal achievement and personal goal, but as it turned out I set a record to be the oldest Australian competitor to win an Australian championship."

Luciani, who also has 51 Australia-wide state championships to his name, stopped racing the Formula 100 class in 1996.

He said it was difficult to prepare for a return to the class, but he put in the hard work.

"I wasn't looking to set a record. Formula 100 is the fastest class in the sport," Luciani said.

"I said to myself, 'what am I doing' because it was hard on my body and myself. To my credit, I trained for three weeks and was able to get the pace.

"I qualified fastest outright in the time trials, won the first heat, the second heat, the third heat, pre-final and final."

Luciani said he might jump back into Formula 100 next year.

"I may be inspired to defend my title," he said.

Luciani will compete in the South Australian Championships at Murray Bridge on November 25 to 27.
He will compete in the over 40s clubman and clubman heavy classes.
