"And cant they just get shareholder approval to raise more if necessary? I dont think they would face much resistance."

Under listing rule 7.1, every listed entity has the ability to issue 15% of
its issued capital without security holder approval in a 12 month period.
Only eligible entities that have obtained security holder approval by
special resolution at an AGM have the ability to issue an additional 10%
of issued capital in a 12 month period under listing rule 7.1A.
