More than 100 of Scott's fans made the trek to Fremantle Cemetery on Friday, where Scott's ashes are interred behind a gated arch that bears his name.
Roy Pails, of Ballarat, who makes the trek to his idol's resting place every five years, said the numbers were well down on visitors to the cemetery on the 25th anniversary of the singer's death.
"That's probably because they're following the AC/DC Black Ice tour around Australia," he said.
Pails, the first fan to rock up to the cemetery on Friday, said 50 more fans had gathered on the lawns beside a seat which carries Scott's name.
Among them were people making their visit to the site, including two Germans bearing AC/DC arm tattoos who had saved up for seven years to be at Fremantle on February 19.
Both East Germans, they remember Scott's last concert in Germany in 1980 when they were 18.
Guitars, singing in cemetery
"We couldn't go, of course, because we couldn't get into West Germany, but we listened on the radio," said Axel Zimmerman, of Leipzig.
"Brian Johnson is good, but Bon Scott was the best.
"We don't have enough money to stay in Perth for AC/DC's concerts next month, but we will see them in Berlin in June."
Zimmerman and his friend Steffen Leibhold, of Leibling, were joined by about a dozen other German fans later in the day.
Said Pails: "They brought their guitars with them and got everyone singing. It's been an AC/DC jam session here on the lawn.
"We'll go down to the Bon Scott statue at Fremantle this evening and then we're going on to celebrate the great man at Little Creatures (bar in Fremantle)."
Bon Scott died in London on February 19, 1980, when he choked on his own vomit following a night of heavy drinking. He was 33.
