Answer 1

Try this

^\s*\*\s*\[ \][^\*]+?[.]com[.]au$

explanation

^        # Assert position at the beginning of a line (at beginning of the string or after a line break character)
\s       # Match a single character that is a “whitespace character” (spaces, tabs, and line breaks)
   *        # Between zero and unlimited times, as many times as possible, giving back as needed (greedy)
\*       # Match the character “*” literally
\s       # Match a single character that is a “whitespace character” (spaces, tabs, and line breaks)
   *        # Between zero and unlimited times, as many times as possible, giving back as needed (greedy)
\[       # Match the character “[” literally
\        # Match the character “ ” literally
\]       # Match the character “]” literally
[^\*]    # Match any character that is NOT a * character
   +?       # Between one and unlimited times, as few times as possible, expanding as needed (lazy)
[.]      # Match the character “.”
com      # Match the characters “com” literally
[.]      # Match the character “.”
au       # Match the characters “au” literally
$        # Assert position at the end of a line (at the end of the string or before a line break character)
