The Australian Securities and Investments Commission (ASIC) is the Commonwealth's corporate regulator. Every Pty Ltd company must lodge: an application for registration on incorporation, an annual review (a A$310 review fee plus confirmation that company details are accurate), and within 28 days of the event a notice of any change to directors, registered address, share capital, or shareholders (Form 484).
Missed filings attract escalating penalties (A$87 for late lodgement plus monthly increments) and persistent non-compliance can lead to deregistration. Most Australian startups outsource ASIC compliance to their accountant or use Cake Equity, Splash Equity, or similar cap-table tools that auto-prepare Form 484 lodgements after each round.
