Underwriting Agreements in Australia: 2026 Guide to Capital Raising

Thinking about raising capital or investing in an Australian offering? Understanding underwriting agreements is key—stay informed and make your next move with confidence.

When an Australian company decides to raise capital—whether through an IPO or a secondary offering—one document sits at the heart of the process: the underwriting agreement.
