Billy Stewart’s version of “Somewhere” does not appear to have charted on the Australian charts in the sources I found; I could verify his Australian chart history only for other songs, like “Summertime.”

What I found

  • The available chart-history source for Billy Stewart lists his charting songs and does not show “Somewhere” among them.
  • A separate chart page confirms “Summertime” had a chart run, but I found no matching Australian chart entry for “Somewhere.”

Practical read

  • So the safest answer is: no documented Australian chart entry found for Billy Stewart’s “Somewhere.”
  • If you were asking about a different release title or a different artist named Stewart, the chart history could be different.
